Frequently asked questions
--------------------------
Q: How much data can Flot cope with?
A: Flot will happily draw everything you send to it so the answer
depends on the browser. The excanvas emulation used for IE (built with
VML) makes IE by far the slowest browser so be sure to test with that
if IE users are in your target group.
1000 points is not a problem, but as soon as you start having more
points than the pixel width, you should probably start thinking about
downsampling/aggregation as this is near the resolution limit of the
chart anyway. If you downsample server-side, you also save bandwidth.
Q: Flot isn't working when I'm using JSON data as source!
A: Actually, Flot loves JSON data, you just got the format wrong.
Double check that you're not inputting strings instead of numbers,
like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and
the error might not show up immediately because Javascript can do some
conversion automatically.
Q: Can I export the graph?
A: This is a limitation of the canvas technology. There's a hook in
the canvas object for getting an image out, but you won't get the tick
labels. And it's not likely to be supported by IE. At this point, your
best bet is probably taking a screenshot, e.g. with PrtScn.
Q: The bars are all tiny in time mode?
A: It's not really possible to determine the bar width automatically.
So you have to set the width with the barWidth option which is NOT in
pixels, but in the units of the x axis (or the y axis for horizontal
bars). For time mode that's milliseconds so the default value of 1
makes the bars 1 millisecond wide.
Q: Can I use Flot with libraries like Mootools or Prototype?
A: Yes, Flot supports it out of the box and it's easy! Just use jQuery
instead of $, e.g. call jQuery.plot instead of $.plot and use
jQuery(something) instead of $(something). As a convenience, you can
put in a DOM element for the graph placeholder where the examples and
the API documentation are using jQuery objects.
Depending on how you include jQuery, you may have to add one line of
code to prevent jQuery from overwriting functions from the other
libraries, see the documentation in jQuery ("Using jQuery with other
libraries") for details.
Q: Flot doesn't work with [insert name of Javascript UI framework]!
A: The only non-standard thing used by Flot is the canvas tag;
otherwise it is simply a series of absolute positioned divs within the
placeholder tag you put in. If this is not working, it's probably
because the framework you're using is doing something weird with the
DOM, or you're using it the wrong way.
A common problem is that there's display:none on a container until the
user does something. Many tab widgets work this way, and there's
nothing wrong with it - you just can't call Flot inside a display:none
container as explained in the README so you need to hold off the Flot
call until the container is actually displayed (or use
visibility:hidden instead of display:none or move the container
off-screen).
If you find there's a specific thing we can do to Flot to help, feel
free to submit a bug report. Otherwise, you're welcome to ask for help
on the forum/mailing list, but please don't submit a bug report to
Flot.

Flot x.x
--------
API changes:
Multiple axes support. Code using dual axes should be changed from
using x2axis/y2axis in the options to using an array (although
backwards-compatibility hooks are in place). For instance,
{
xaxis: { ... }, x2axis: { ... },
yaxis: { ... }, y2axis: { ... }
}
becomes
{
xaxes: [ { ... }, { ... } ],
yaxes: [ { ... }, { ... } ]
}
Note that if you're just using one axis, continue to use the
xaxis/yaxis directly (it now sets the default settings for the
arrays). Plugins touching the axes must be ported to take the extra
axes into account, a couple of helper functions have been added for
that purpose, check the source.
"tickColor" on the grid options is now deprecated in favour of a
corresponding option on the axes, so { grid: { tickColor: "#000" }}
becomes { xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} },
but if you just configure a base color Flot will now autogenerate a
tick color by adding transparency. Backwards-compatibility hooks are
in place.
Changes:
- Support for specifying a bottom for each point for line charts when
filling them, this means that an arbitrary bottom can be used
instead of just the x axis (based on patches patiently provided by
Roman V. Prikhodchenko).
- New fillbetween plugin that can compute a bottom for a series from
another series, useful for filling areas between lines (see new
example percentiles.html for a use case).
- More predictable handling of gaps for the stacking plugin, now all
undefined ranges are skipped.
- Stacking plugin can stack horizontal bar charts.
- Navigate plugin now redraws the plot while panning instead of only
after the fact (can be disabled by setting the pan.frameRate option
to null), raised by lastthemy (issue 235).
- Date formatter now accepts %0m and %0d to get a zero-padded month or
day (issue raised by Maximillian Dornseif).
- Revamped internals to support an unlimited number of axes, not just
dual (sponsored by Flight Data Services,
www.flightdataservices.com).
- New setting on axes, "tickLength", to control the size of ticks or
turn them off without turning off the labels.
- Axis labels are now put in container divs with classes, for instance
labels in the x axes can be reached via ".xAxis .tickLabel".
- Support for setting the color of an axis (sponsored by Flight Data
Services, www.flightdataservices.com).
- Tick color is now auto-generated as the base color with some
transparency (unless you override it).
- Support for aligning ticks in the axes with "alignTicksWithAxis" to
ensure that they appear next to each other rather than in between,
at the expense of possibly awkward tick steps (sponsored by Flight
Data Services, www.flightdataservices.com).
- Support for customizing the point type through a callback when
plotting points and new symbol plugin with some predefined point
types (sponsored by Utility Data Corporation).
- New hooks: drawSeries
Bug fixes:
- Fixed problem with findNearbyItem and bars on top of each other
(reported by ragingchikn, issue 242).
- Fixed problem with ticks and the border (based on patch from
ultimatehustler69, issue 236).
- Fixed problem with plugins adding options to the series objects.
- Fixed a problem introduced in 0.6 with specifying a gradient with {
brightness: x, opacity: y }.
- Don't use $.browser.msie, check for getContext on the created canvas
element instead and try to use excanvas if it's not found.
- highlight(s, index) was looking up the point in the original s.data
instead of in the computed datapoints array, which breaks with
plugins that modify the datapoints (such as the stacking plugin).
Issue 316 reported by curlypaul924.
- More robust handling of axis from data passed in from getData()
(problem reported by Morgan).
- Fixed problem with turning off bar outline (issue 253, fix by Jordi
Castells).
- Check the selection passed into setSelection in the selection
plugin, to guard against errors when synchronizing plots (fix by Lau
Bech Lauritzen).
- Fix bug in crosshair code with mouseout resetting the crosshair even
if it is locked (fix by Lau Bech Lauritzen).
- Fix bug with points plotting using line width from lines rather than
points.
Flot 0.6
--------
API changes:
1. Selection support has been moved to a plugin. Thus if you're
passing selection: { mode: something }, you MUST include the file
jquery.flot.selection.js after jquery.flot.js. This reduces the size
of base Flot and makes it easier to customize the selection as well as
improving code clarity. The change is based on a patch from andershol.
2. In the global options specified in the $.plot command,
"lines", "points", "bars" and "shadowSize" have been moved to a
sub-object called "series", i.e.
$.plot(placeholder, data, { lines: { show: true }})
should be changed to
$.plot(placeholder, data, { series: { lines: { show: true }}})
All future series-specific options will go into this sub-object to
simplify plugin writing. Backward-compatibility code is in place, so
old code should not break.
3. "plothover" no longer provides the original data point, but instead
a normalized one, since there may be no corresponding original point.
4. Due to a bug in previous versions of jQuery, you now need at least
jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some
improvements in event handling speed.
Changes:
- Added support for disabling interactivity for specific data series
(request from Ronald Schouten and Steve Upton).
- Flot now calls $() on the placeholder and optional legend container
passed in so you can specify DOM elements or CSS expressions to make
it easier to use Flot with libraries like Prototype or Mootools or
through raw JSON from Ajax responses.
- A new "plotselecting" event is now emitted while the user is making
a selection.
- The "plothover" event is now emitted immediately instead of at most
10 times per second, you'll have to put in a setTimeout yourself if
you're doing something really expensive on this event.
- The built-in date formatter can now be accessed as
$.plot.formatDate(...) (suggestion by Matt Manela) and even
replaced.
- Added "borderColor" option to the grid (patch from Amaury Chamayou
and patch from Mike R. Williamson).
- Added support for gradient backgrounds for the grid, take a look at
the "setting options" example (based on patch from Amaury Chamayou,
issue 90).
- Gradient bars (suggestion by stefpet).
- Added a "plotunselected" event which is triggered when the selection
is removed, see "selection" example (suggestion by Meda Ugo);
- The option legend.margin can now specify horizontal and vertical
margins independently (suggestion by someone who's annoyed).
- Data passed into Flot is now copied to a new canonical format to
enable further processing before it hits the drawing routines. As a
side-effect, this should make Flot more robust in the face of bad
data (and fixes issue 112).
- Step-wise charting: line charts have a new option "steps" that when
set to true connects the points with horizontal/vertical steps
instead of diagonal lines.
- The legend labelFormatter now passes the series in addition to just
the label (suggestion by Vincent Lemeltier).
- Horizontal bars (based on patch by Jason LeBrun).
- Support for partial bars by specifying a third coordinate, i.e. they
don't have to start from the axis. This can be used to make stacked
bars.
- New option to disable the (grid.show).
- Added pointOffset method for converting a point in data space to an
offset within the placeholder.
- Plugin system: register an init method in the $.flot.plugins array
to get started, see PLUGINS.txt for details on how to write plugins
(it's easy). There are also some extra methods to enable access to
internal state.
- Hooks: you can register functions that are called while Flot is
crunching the data and doing the plot. This can be used to modify
Flot without changing the source, useful for writing plugins. Some
hooks are defined, more are likely to come.
- Threshold plugin: you can set a threshold and a color, and the data
points below that threshold will then get the color. Useful for
marking data below 0, for instance.
- Stack plugin: you can specify a stack key for each series to have
them summed. This is useful for drawing additive/cumulative graphs
with bars and (currently unfilled) lines.
- Crosshairs plugin: trace the mouse position on the axes, enable with
crosshair: { mode: "x"} (see the new tracking example for a use).
- Image plugin: plot prerendered images.
- Navigation plugin for panning and zooming a plot.
- More configurable grid.
- Axis transformation support, useful for non-linear plots, e.g. log
axes and compressed time axes (like omitting weekends).
- Support for twelve-hour date formatting (patch by Forrest Aldridge).
- The color parsing code in Flot has been cleaned up and split out so
it's now available as a separate jQuery plugin. It's included inline
in the Flot source to make dependency managing easier. This also
makes it really easy to use the color helpers in Flot plugins.
Bug fixes:
- Fixed two corner-case bugs when drawing filled curves (report and
analysis by Joshua Varner).
- Fix auto-adjustment code when setting min to 0 for an axis where the
dataset is completely flat on that axis (report by chovy).
- Fixed a bug with passing in data from getData to setData when the
secondary axes are used (issue 65, reported by nperelman).
- Fixed so that it is possible to turn lines off when no other chart
type is shown (based on problem reported by Glenn Vanderburg), and
fixed so that setting lineWidth to 0 also hides the shadow (based on
problem reported by Sergio Nunes).
- Updated mousemove position expression to the latest from jQuery (bug
reported by meyuchas).
- Use CSS borders instead of background in legend (fix printing issue 25
and 45).
- Explicitly convert axis min/max to numbers.
- Fixed a bug with drawing marking lines with different colors
(reported by Khurram).
- Fixed a bug with returning y2 values in the selection event (fix
by exists, issue 75).
- Only set position relative on placeholder if it hasn't already a
position different from static (reported by kyberneticist, issue 95).
- Don't round markings to prevent sub-pixel problems (reported by Dan
Lipsitt).
- Make the grid border act similarly to a regular CSS border, i.e.
prevent it from overlapping the plot itself. This also fixes a
problem with anti-aliasing when the width is 1 pixel (reported by
Anthony Ettinger).
- Imported version 3 of excanvas and fixed two issues with the newer
version. Hopefully, this will make Flot work with IE8 (nudge by
Fabien Menager, further analysis by Booink, issue 133).
- Changed the shadow code for lines to hopefully look a bit better
with vertical lines.
- Round tick positions to avoid possible problems with fractions
(suggestion by Fred, issue 130).
- Made the heuristic for determining how many ticks to aim for a bit
smarter.
- Fix for uneven axis margins (report and patch by Paul Kienzle) and
snapping to ticks (concurrent report and patch by lifthrasiir).
- Fixed bug with slicing in findNearbyItems (patch by zollman).
- Make heuristic for x axis label widths more dynamic (patch by
rickinhethuis).
- Make sure points on top take precedence when finding nearby points
when hovering (reported by didroe, issue 224).
Flot 0.5
--------
Backwards API change summary: Timestamps are now in UTC. Also
"selected" event -> becomes "plotselected" with new data, the
parameters for setSelection are now different (but backwards
compatibility hooks are in place), coloredAreas becomes markings with
a new interface (but backwards compatibility hooks are in place).
Interactivity: added a new "plothover" event and this and the
"plotclick" event now returns the closest data item (based on patch by
/david, patch by Mark Byers for bar support). See the revamped
"interacting with the data" example for some hints on what you can do.
Highlighting: you can now highlight points and datapoints are
autohighlighted when you hover over them (if hovering is turned on).
Support for dual axis has been added (based on patch by someone who's
annoyed and /david). For each data series you can specify which axes
it belongs to, and there are two more axes, x2axis and y2axis, to
customize. This affects the "selected" event which has been renamed to
"plotselected" and spews out { xaxis: { from: -10, to: 20 } ... },
setSelection in which the parameters are on a new form (backwards
compatible hooks are in place so old code shouldn't break) and
markings (formerly coloredAreas).
Timestamps in time mode are now displayed according to
UTC instead of the time zone of the visitor. This affects the way the
timestamps should be input; you'll probably have to offset the
timestamps according to your local time zone. It also affects any
custom date handling code (which basically now should use the
equivalent UTC date mehods, e.g. .setUTCMonth() instead of
.setMonth().
Added support for specifying the size of tick labels (axis.labelWidth,
axis.labelHeight). Useful for specifying a max label size to keep
multiple plots aligned.
Markings, previously coloredAreas, are now specified as ranges on the
axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings
you can now draw horizontal/vertical lines by setting from and to to
the same coordinate (idea from line support patch by by Ryan Funduk).
The "fill" option can now be a number that specifies the opacity of
the fill.
You can now specify a coordinate as null (like [2, null]) and Flot
will take the other coordinate into account when scaling the axes
(based on patch by joebno).
New option for bars "align". Set it to "center" to center the bars on
the value they represent.
setSelection now takes a second parameter which you can use to prevent
the method from firing the "plotselected" handler.
Using the "container" option in legend now overwrites the container
element instead of just appending to it (fixes infinite legend bug,
reported by several people, fix by Brad Dewey).
Fixed a bug in calculating spacing around the plot (reported by
timothytoe). Fixed a bug in finding max values for all-negative data
sets. Prevent the possibility of eternal looping in tick calculations.
Fixed a bug when borderWidth is set to 0 (reported by
Rob/sanchothefat). Fixed a bug with drawing bars extending below 0
(reported by James Hewitt, patch by Ryan Funduk). Fixed a
bug with line widths of bars (reported by MikeM). Fixed a bug with
'nw' and 'sw' legend positions. Improved the handling of axis
auto-scaling with bars. Fixed a bug with multi-line x-axis tick
labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
Flot 0.4
--------
API changes: deprecated axis.noTicks in favor of just specifying the
number as axis.ticks. So "xaxis: { noTicks: 10 }" becomes
"xaxis: { ticks: 10 }"
Time series support. Specify axis.mode: "time", put in Javascript
timestamps as data, and Flot will automatically spit out sensible
ticks. Take a look at the two new examples. The format can be
customized with axis.timeformat and axis.monthNames, or if that fails
with axis.tickFormatter.
Support for colored background areas via grid.coloredAreas. Specify an
array of { x1, y1, x2, y2 } objects or a function that returns these
given { xmin, xmax, ymin, ymax }.
More members on the plot object (report by Chris Davies and others).
"getData" for inspecting the assigned settings on data series (e.g.
color) and "setData", "setupGrid" and "draw" for updating the contents
without a total replot.
The default number of ticks to aim for is now dependent on the size of
the plot in pixels. Support for customizing tick interval sizes
directly with axis.minTickSize and axis.tickSize.
Cleaned up the automatic axis scaling algorithm and fixed how it
interacts with ticks. Also fixed a couple of tick-related corner case
bugs (one reported by mainstreetmark, another reported by timothytoe).
The option axis.tickFormatter now takes a function with two
parameters, the second parameter is an optional object with
information about the axis. It has min, max, tickDecimals, tickSize.
Added support for segmented lines (based on patch from Michael
MacDonald) and for ignoring null and bad values (suggestion from Nick
Konidaris and joshwaihi).
Added support for changing the border width (joebno and safoo).
Label colors can be changed via CSS by selecting the tickLabel class.
Fixed a bug in handling single-item bar series (reported by Emil
Filipov). Fixed erratic behaviour when interacting with the plot
with IE 7 (reported by Lau Bech Lauritzen). Prevent IE/Safari text
selection when selecting stuff on the canvas.
Flot 0.3
--------
This is mostly a quick-fix release because jquery.js wasn't included
in the previous zip/tarball.
Support clicking on the plot. Turn it on with grid: { clickable: true },
then you get a "plotclick" event on the graph placeholder with the
position in units of the plot.
Fixed a bug in dealing with data where min = max, thanks to Michael
Messinides.
Include jquery.js in the zip/tarball.
Flot 0.2
--------
Added support for putting a background behind the default legend. The
default is the partly transparent background color. Added
backgroundColor and backgroundOpacity to the legend options to control
this.
The ticks options can now be a callback function that takes one
parameter, an object with the attributes min and max. The function
should return a ticks array.
Added labelFormatter option in legend, useful for turning the legend
labels into links.
Fixed a couple of bugs.
The API should now be fully documented.
Patch from Guy Fraser to make parts of the code smaller.
API changes: Moved labelMargin option to grid from x/yaxis.
Flot 0.1
--------
First public release.

Writing plugins
---------------
To make a new plugin, create an init function and a set of options (if
needed), stuff it into an object and put it in the $.plot.plugins
array. For example:
function myCoolPluginInit(plot) { plot.coolstring = "Hello!" };
var myCoolOptions = { coolstuff: { show: true } }
$.plot.plugins.push({ init: myCoolPluginInit, options: myCoolOptions });
// now when $.plot is called, the returned object will have the
// attribute "coolstring"
Now, given that the plugin might run in many different places, it's
a good idea to avoid leaking names. We can avoid this by wrapping the
above lines in an anonymous function which we call immediately, like
this: (function () { inner code ... })(). To make it even more robust
in case $ is not bound to jQuery but some other Javascript library, we
can write it as
(function ($) {
// plugin definition
// ...
})(jQuery);
Here is a simple debug plugin which alerts each of the series in the
plot. It has a single option that control whether it is enabled and
how much info to output:
(function ($) {
function init(plot) {
var debugLevel = 1;
function checkDebugEnabled(plot, options) {
if (options.debug) {
debugLevel = options.debug;
plot.hooks.processDatapoints.push(alertSeries);
}
}
function alertSeries(plot, series, datapoints) {
var msg = "series " + series.label;
if (debugLevel > 1)
msg += " with " + series.data.length + " points";
alert(msg);
}
plot.hooks.processOptions.push(checkDebugEnabled);
}
var options = { debug: 0 };
$.plot.plugins.push({
init: init,
options: options,
name: "simpledebug",
version: "0.1"
});
})(jQuery);
We also define "name" and "version". It's not used by Flot, but might
be helpful for other plugins in resolving dependencies.
Put the above in a file named "jquery.flot.debug.js", include it in an
HTML page and then it can be used with:
$.plot($("#placeholder"), [...], { debug: 2 });
This simple plugin illustrates a couple of points:
- It uses the anonymous function trick to avoid name pollution.
- It can be enabled/disabled through an option.
- Variables in the init function can be used to store plot-specific
state between the hooks.
Options guidelines
==================
Plugins should always support appropriate options to enable/disable
them because the plugin user may have several plots on the same page
where only one should use the plugin.
If the plugin needs series-specific options, you can put them in
"series" in the options object, e.g.
var options = {
series: {
downsample: {
algorithm: null,
maxpoints: 1000
}
}
}
Then they will be copied by Flot into each series, providing the
defaults in case the plugin user doesn't specify any. Again, in most
cases it's probably a good idea if the plugin is turned off rather
than on per default, just like most of the powerful features in Flot.
Think hard and long about naming the options. These names are going to
be public API, and code is going to depend on them if the plugin is
successful.

About
-----
Flot is a Javascript plotting library for jQuery. Read more at the
website:
http://code.google.com/p/flot/
Take a look at the examples linked from above, they should give a good
impression of what Flot can do and the source code of the examples is
probably the fastest way to learn how to use Flot.
Installation
------------
Just include the Javascript file after you've included jQuery.
Note that you need to get a version of Excanvas (e.g. the one bundled
with Flot) which is canvas emulation on Internet Explorer. You can
include the excanvas script like this:
<!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.pack.js"></script><![endif]-->
If it's not working on your development IE 6.0, check that it has
support for VML which excanvas is relying on. It appears that some
stripped down versions used for test environments on virtual machines
lack the VML support.
Also note that you need at least jQuery 1.2.6 (but at least jQuery
1.3.2 is recommended for interactive charts because of performance
improvements in event handling).
Basic usage
-----------
Create a placeholder div to put the graph in:
<div id="placeholder"></div>
You need to set the width and height of this div, otherwise the plot
library doesn't know how to scale the graph. You can do it inline like
this:
<div id="placeholder" style="width:600px;height:300px"></div>
You can also do it with an external stylesheet. Make sure that the
placeholder isn't within something with a display:none CSS property -
in that case, Flot has trouble measuring label dimensions which
results in garbled looks and might have trouble measuring the
placeholder dimensions which is fatal (it'll throw an exception).
Then when the div is ready in the DOM, which is usually on document
ready, run the plot function:
$.plot($("#placeholder"), data, options);
Here, data is an array of data series and options is an object with
settings if you want to customize the plot. Take a look at the
examples for some ideas of what to put in or look at the reference
in the file "API.txt". Here's a quick example that'll draw a line from
(0, 0) to (1, 1):
$.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } });
The plot function immediately draws the chart and then returns a plot
object with a couple of methods.
What's with the name?
---------------------
First: it's pronounced with a short o, like "plot". Not like "flawed".
So "Flot" rhymes with "plot".
And if you look up "flot" in a Danish-to-English dictionary, some up
the words that come up are "good-looking", "attractive", "stylish",
"smart", "impressive", "extravagant". One of the main goals with Flot
is pretty looks.

/*
Flot plugin for showing crosshairs, thin lines, when the mouse hovers
over the plot.
crosshair: {
mode: null or "x" or "y" or "xy"
color: color
lineWidth: number
}
Set the mode to one of "x", "y" or "xy". The "x" mode enables a
vertical crosshair that lets you trace the values on the x axis, "y"
enables a horizontal crosshair and "xy" enables them both. "color" is
the color of the crosshair (default is "rgba(170, 0, 0, 0.80)"),
"lineWidth" is the width of the drawn lines (default is 1).
The plugin also adds four public methods:
- setCrosshair(pos)
Set the position of the crosshair. Note that this is cleared if
the user moves the mouse. "pos" is in coordinates of the plot and
should be on the form { x: xpos, y: ypos } (you can use x2/x3/...
if you're using multiple axes), which is coincidentally the same
format as what you get from a "plothover" event. If "pos" is null,
the crosshair is cleared.
- clearCrosshair()
Clear the crosshair.
- lockCrosshair(pos)
Cause the crosshair to lock to the current location, no longer
updating if the user moves the mouse. Optionally supply a position
(passed on to setCrosshair()) to move it to.
Example usage:
var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } };
$("#graph").bind("plothover", function (evt, position, item) {
if (item) {
// Lock the crosshair to the data point being hovered
myFlot.lockCrosshair({ x: item.datapoint[0], y: item.datapoint[1] });
}
else {
// Return normal crosshair operation
myFlot.unlockCrosshair();
}
});
- unlockCrosshair()
Free the crosshair to move again after locking it.

/*
Flot plugin for computing bottoms for filled line and bar charts.
The case: you've got two series that you want to fill the area
between. In Flot terms, you need to use one as the fill bottom of the
other. You can specify the bottom of each data point as the third
coordinate manually, or you can use this plugin to compute it for you.
In order to name the other series, you need to give it an id, like this
var dataset = [
{ data: [ ... ], id: "foo" } , // use default bottom
{ data: [ ... ], fillBetween: "foo" }, // use first dataset as bottom
];
$.plot($("#placeholder"), dataset, { line: { show: true, fill: true }});
As a convenience, if the id given is a number that doesn't appear as
an id in the series, it is interpreted as the index in the array
instead (so fillBetween: 0 can also mean the first series).
Internally, the plugin modifies the datapoints in each series. For
line series, extra data points might be inserted through
interpolation. Note that at points where the bottom line is not
defined (due to a null point or start/end of line), the current line
will show a gap too. The algorithm comes from the jquery.flot.stack.js

/*
Flot plugin for plotting images, e.g. useful for putting ticks on a
prerendered complex visualization.
The data syntax is [[image, x1, y1, x2, y2], ...] where (x1, y1) and
(x2, y2) are where you intend the two opposite corners of the image to
end up in the plot. Image must be a fully loaded Javascript image (you
can make one with new Image()). If the image is not complete, it's
skipped when plotting.
There are two helpers included for retrieving images. The easiest work
the way that you put in URLs instead of images in the data (like
["myimage.png", 0, 0, 10, 10]), then call $.plot.image.loadData(data,
options, callback) where data and options are the same as you pass in
to $.plot. This loads the images, replaces the URLs in the data with
the corresponding images and calls "callback" when all images are
loaded (or failed loading). In the callback, you can then call $.plot
with the data set. See the included example.
A more low-level helper, $.plot.image.load(urls, callback) is also
included. Given a list of URLs, it calls callback with an object
mapping from URL to Image object when all images are loaded or have
failed loading.
Options for the plugin are
series: {
images: {
show: boolean
anchor: "corner" or "center"
alpha: [0,1]
}
}
which can be specified for a specific series
$.plot($("#placeholder"), [{ data: [ ... ], images: { ... } ])
Note that because the data format is different from usual data points,
you can't use images with anything else in a specific data series.
Setting "anchor" to "center" causes the pixels in the image to be
anchored at the corner pixel centers inside of at the pixel corners,
effectively letting half a pixel stick out to each side in the plot.
A possible future direction could be support for tiling for large
images (like Google Maps).

/*
Flot plugin for adding panning and zooming capabilities to a plot.
The default behaviour is double click and scrollwheel up/down to zoom
in, drag to pan. The plugin defines plot.zoom({ center }),
plot.zoomOut() and plot.pan(offset) so you easily can add custom
controls. It also fires a "plotpan" and "plotzoom" event when
something happens, useful for synchronizing plots.
Options:
zoom: {
interactive: false
trigger: "dblclick" // or "click" for single click
amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out)
}
pan: {
interactive: false
frameRate: 20
}
xaxis, yaxis, x2axis, y2axis: {
zoomRange: null // or [number, number] (min range, max range)
panRange: null // or [number, number] (min, max)
}
"interactive" enables the built-in drag/click behaviour. If you enable
interactive for pan, then you'll have a basic plot that supports
moving around; the same for zoom.
"amount" specifies the default amount to zoom in (so 1.5 = 150%)
relative to the current viewport.
"frameRate" specifies the maximum number of times per second the plot
will update itself while the user is panning around on it (set to null
to disable intermediate pans, the plot will then not update until the
mouse button is released).
"zoomRange" is the interval in which zooming can happen, e.g. with
zoomRange: [1, 100] the zoom will never scale the axis so that the
difference between min and max is smaller than 1 or larger than 100.
You can set either end to null to ignore, e.g. [1, null].
"panRange" confines the panning to stay within a range, e.g. with
panRange: [-10, 20] panning stops at -10 in one end and at 20 in the
other. Either can be null, e.g. [-10, null].
Example API usage:
plot = $.plot(...);
// zoom default amount in on the pixel (10, 20)
plot.zoom({ center: { left: 10, top: 20 } });
// zoom out again
plot.zoomOut({ center: { left: 10, top: 20 } });
// zoom 200% in on the pixel (10, 20)
plot.zoom({ amount: 2, center: { left: 10, top: 20 } });
// pan 100 pixels to the left and 20 down
plot.pan({ left: -100, top: 20 })
Here, "center" specifies where the center of the zooming should
happen. Note that this is defined in pixel space, not the space of the
data points (you can use the p2c helpers on the axes in Flot to help
you convert between these).
"amount" is the amount to zoom the viewport relative to the current
range, so 1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is
70% (zoom out). You can set the default in the options.

/*
Flot plugin for rendering pie charts. The plugin assumes the data is
coming is as a single data value for each series, and each of those
values is a positive value or zero (negative numbers don't make
any sense and will cause strange effects). The data values do
NOT need to be passed in as percentage values because it
internally calculates the total and percentages.
* Created by Brian Medendorp, June 2009
* Updated November 2009 with contributions from: btburnett3, Anthony Aragues and Xavi Ivars
* Changes:
2009-10-22: lineJoin set to round
2009-10-23: IE full circle fix, donut
2009-11-11: Added basic hover from btburnett3 - does not work in IE, and center is off in Chrome and Opera
2009-11-17: Added IE hover capability submitted by Anthony Aragues
2009-11-18: Added bug fix submitted by Xavi Ivars (issues with arrays when other JS libraries are included as well)
Available options are:
series: {
pie: {
show: true/false
radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
offset: {
top: integer value to move the pie up or down
left: integer value to move the pie left or right, or 'auto'
},
stroke: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
width: integer pixel width of the stroke
},
label: {
show: true/false, or 'auto'
formatter: a user-defined function that modifies the text/style of the label text
radius: 0-1 for percentage of fullsize, or a specified pixel length
background: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
opacity: 0-1
},
threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
},
combine: {
threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
label: any text value of what the combined slice should be labeled
}
highlight: {
opacity: 0-1
}
}
}
More detail and specific examples can be found in the included HTML file.

/*
Flot plugin for selecting regions.
The plugin defines the following options:
selection: {
mode: null or "x" or "y" or "xy",
color: color
}
Selection support is enabled by setting the mode to one of "x", "y" or
"xy". In "x" mode, the user will only be able to specify the x range,
similarly for "y" mode. For "xy", the selection becomes a rectangle
where both ranges can be specified. "color" is color of the selection.
When selection support is enabled, a "plotselected" event will be
emitted on the DOM element you passed into the plot function. The
event handler gets a parameter with the ranges selected on the axes,
like this:
placeholder.bind("plotselected", function(event, ranges) {
alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to)
// similar for yaxis - with multiple axes, the extra ones are in
// x2axis, x3axis, ...
});
The "plotselected" event is only fired when the user has finished
making the selection. A "plotselecting" event is fired during the
process with the same parameters as the "plotselected" event, in case
you want to know what's happening while it's happening,
A "plotunselected" event with no arguments is emitted when the user
clicks the mouse to remove the selection.
The plugin allso adds the following methods to the plot object:
- setSelection(ranges, preventEvent)
Set the selection rectangle. The passed in ranges is on the same
form as returned in the "plotselected" event. If the selection mode
is "x", you should put in either an xaxis range, if the mode is "y"
you need to put in an yaxis range and both xaxis and yaxis if the
selection mode is "xy", like this:
setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } });
setSelection will trigger the "plotselected" event when called. If
you don't want that to happen, e.g. if you're inside a
"plotselected" handler, pass true as the second parameter. If you
are using multiple axes, you can specify the ranges on any of those,
e.g. as x2axis/x3axis/... instead of xaxis, the plugin picks the
first one it sees.
- clearSelection(preventEvent)
Clear the selection rectangle. Pass in true to avoid getting a
"plotunselected" event.
- getSelection()
Returns the current selection in the same format as the
"plotselected" event. If there's currently no selection, the
function returns null.

/*
Flot plugin for stacking data sets, i.e. putting them on top of each
other, for accumulative graphs.
The plugin assumes the data is sorted on x (or y if stacking
horizontally). For line charts, it is assumed that if a line has an
undefined gap (from a null point), then the line above it should have
the same gap - insert zeros instead of "null" if you want another
behaviour. This also holds for the start and end of the chart. Note
that stacking a mix of positive and negative values in most instances
doesn't make sense (so it looks weird).
Two or more series are stacked when their "stack" attribute is set to
the same key (which can be any number or string or just "true"). To
specify the default stack, you can set
series: {
stack: null or true or key (number/string)
}
or specify it for a specific series
$.plot($("#placeholder"), [{ data: [ ... ], stack: true }])
The stacking order is determined by the order of the data series in
the array (later series end up on top of the previous).
Internally, the plugin modifies the datapoints in each series, adding
an offset to the y value. For line series, extra data points are
inserted through interpolation. If there's a second y value, it's also
adjusted (e.g for bar charts or filled areas).

Frequently asked questions
--------------------------
Q: How much data can Flot cope with?
A: Flot will happily draw everything you send to it so the answer
depends on the browser. The excanvas emulation used for IE (built with
VML) makes IE by far the slowest browser so be sure to test with that
if IE users are in your target group.
1000 points is not a problem, but as soon as you start having more
points than the pixel width, you should probably start thinking about
downsampling/aggregation as this is near the resolution limit of the
chart anyway. If you downsample server-side, you also save bandwidth.
Q: Flot isn't working when I'm using JSON data as source!
A: Actually, Flot loves JSON data, you just got the format wrong.
Double check that you're not inputting strings instead of numbers,
like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and
the error might not show up immediately because Javascript can do some
conversion automatically.
Q: Can I export the graph?
A: This is a limitation of the canvas technology. There's a hook in
the canvas object for getting an image out, but you won't get the tick
labels. And it's not likely to be supported by IE. At this point, your
best bet is probably taking a screenshot, e.g. with PrtScn.
Q: The bars are all tiny in time mode?
A: It's not really possible to determine the bar width automatically.
So you have to set the width with the barWidth option which is NOT in
pixels, but in the units of the x axis (or the y axis for horizontal
bars). For time mode that's milliseconds so the default value of 1
makes the bars 1 millisecond wide.
Q: Can I use Flot with libraries like Mootools or Prototype?
A: Yes, Flot supports it out of the box and it's easy! Just use jQuery
instead of $, e.g. call jQuery.plot instead of $.plot and use
jQuery(something) instead of $(something). As a convenience, you can
put in a DOM element for the graph placeholder where the examples and
the API documentation are using jQuery objects.
Depending on how you include jQuery, you may have to add one line of
code to prevent jQuery from overwriting functions from the other
libraries, see the documentation in jQuery ("Using jQuery with other
libraries") for details.
Q: Flot doesn't work with [insert name of Javascript UI framework]!
A: The only non-standard thing used by Flot is the canvas tag;
otherwise it is simply a series of absolute positioned divs within the
placeholder tag you put in. If this is not working, it's probably
because the framework you're using is doing something weird with the
DOM, or you're using it the wrong way.
A common problem is that there's display:none on a container until the
user does something. Many tab widgets work this way, and there's
nothing wrong with it - you just can't call Flot inside a display:none
container as explained in the README so you need to hold off the Flot
call until the container is actually displayed (or use
visibility:hidden instead of display:none or move the container
off-screen).
If you find there's a specific thing we can do to Flot to help, feel
free to submit a bug report. Otherwise, you're welcome to ask for help
on the forum/mailing list, but please don't submit a bug report to
Flot.

Flot x.x
--------
API changes:
Multiple axes support. Code using dual axes should be changed from
using x2axis/y2axis in the options to using an array (although
backwards-compatibility hooks are in place). For instance,
{
xaxis: { ... }, x2axis: { ... },
yaxis: { ... }, y2axis: { ... }
}
becomes
{
xaxes: [ { ... }, { ... } ],
yaxes: [ { ... }, { ... } ]
}
Note that if you're just using one axis, continue to use the
xaxis/yaxis directly (it now sets the default settings for the
arrays). Plugins touching the axes must be ported to take the extra
axes into account, a couple of helper functions have been added for
that purpose, check the source.
"tickColor" on the grid options is now deprecated in favour of a
corresponding option on the axes, so { grid: { tickColor: "#000" }}
becomes { xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} },
but if you just configure a base color Flot will now autogenerate a
tick color by adding transparency. Backwards-compatibility hooks are
in place.
Changes:
- Support for specifying a bottom for each point for line charts when
filling them, this means that an arbitrary bottom can be used
instead of just the x axis (based on patches patiently provided by
Roman V. Prikhodchenko).
- New fillbetween plugin that can compute a bottom for a series from
another series, useful for filling areas between lines (see new
example percentiles.html for a use case).
- More predictable handling of gaps for the stacking plugin, now all
undefined ranges are skipped.
- Stacking plugin can stack horizontal bar charts.
- Navigate plugin now redraws the plot while panning instead of only
after the fact (can be disabled by setting the pan.frameRate option
to null), raised by lastthemy (issue 235).
- Date formatter now accepts %0m and %0d to get a zero-padded month or
day (issue raised by Maximillian Dornseif).
- Revamped internals to support an unlimited number of axes, not just
dual (sponsored by Flight Data Services,
www.flightdataservices.com).
- New setting on axes, "tickLength", to control the size of ticks or
turn them off without turning off the labels.
- Axis labels are now put in container divs with classes, for instance
labels in the x axes can be reached via ".xAxis .tickLabel".
- Support for setting the color of an axis (sponsored by Flight Data
Services, www.flightdataservices.com).
- Tick color is now auto-generated as the base color with some
transparency (unless you override it).
- Support for aligning ticks in the axes with "alignTicksWithAxis" to
ensure that they appear next to each other rather than in between,
at the expense of possibly awkward tick steps (sponsored by Flight
Data Services, www.flightdataservices.com).
- Support for customizing the point type through a callback when
plotting points and new symbol plugin with some predefined point
types (sponsored by Utility Data Corporation).
- New hooks: drawSeries
Bug fixes:
- Fixed problem with findNearbyItem and bars on top of each other
(reported by ragingchikn, issue 242).
- Fixed problem with ticks and the border (based on patch from
ultimatehustler69, issue 236).
- Fixed problem with plugins adding options to the series objects.
- Fixed a problem introduced in 0.6 with specifying a gradient with {
brightness: x, opacity: y }.
- Don't use $.browser.msie, check for getContext on the created canvas
element instead and try to use excanvas if it's not found.
- highlight(s, index) was looking up the point in the original s.data
instead of in the computed datapoints array, which breaks with
plugins that modify the datapoints (such as the stacking plugin).
Issue 316 reported by curlypaul924.
- More robust handling of axis from data passed in from getData()
(problem reported by Morgan).
- Fixed problem with turning off bar outline (issue 253, fix by Jordi
Castells).
- Check the selection passed into setSelection in the selection
plugin, to guard against errors when synchronizing plots (fix by Lau
Bech Lauritzen).
- Fix bug in crosshair code with mouseout resetting the crosshair even
if it is locked (fix by Lau Bech Lauritzen).
- Fix bug with points plotting using line width from lines rather than
points.
Flot 0.6
--------
API changes:
1. Selection support has been moved to a plugin. Thus if you're
passing selection: { mode: something }, you MUST include the file
jquery.flot.selection.js after jquery.flot.js. This reduces the size
of base Flot and makes it easier to customize the selection as well as
improving code clarity. The change is based on a patch from andershol.
2. In the global options specified in the $.plot command,
"lines", "points", "bars" and "shadowSize" have been moved to a
sub-object called "series", i.e.
$.plot(placeholder, data, { lines: { show: true }})
should be changed to
$.plot(placeholder, data, { series: { lines: { show: true }}})
All future series-specific options will go into this sub-object to
simplify plugin writing. Backward-compatibility code is in place, so
old code should not break.
3. "plothover" no longer provides the original data point, but instead
a normalized one, since there may be no corresponding original point.
4. Due to a bug in previous versions of jQuery, you now need at least
jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some
improvements in event handling speed.
Changes:
- Added support for disabling interactivity for specific data series
(request from Ronald Schouten and Steve Upton).
- Flot now calls $() on the placeholder and optional legend container
passed in so you can specify DOM elements or CSS expressions to make
it easier to use Flot with libraries like Prototype or Mootools or
through raw JSON from Ajax responses.
- A new "plotselecting" event is now emitted while the user is making
a selection.
- The "plothover" event is now emitted immediately instead of at most
10 times per second, you'll have to put in a setTimeout yourself if
you're doing something really expensive on this event.
- The built-in date formatter can now be accessed as
$.plot.formatDate(...) (suggestion by Matt Manela) and even
replaced.
- Added "borderColor" option to the grid (patch from Amaury Chamayou
and patch from Mike R. Williamson).
- Added support for gradient backgrounds for the grid, take a look at
the "setting options" example (based on patch from Amaury Chamayou,
issue 90).
- Gradient bars (suggestion by stefpet).
- Added a "plotunselected" event which is triggered when the selection
is removed, see "selection" example (suggestion by Meda Ugo);
- The option legend.margin can now specify horizontal and vertical
margins independently (suggestion by someone who's annoyed).
- Data passed into Flot is now copied to a new canonical format to
enable further processing before it hits the drawing routines. As a
side-effect, this should make Flot more robust in the face of bad
data (and fixes issue 112).
- Step-wise charting: line charts have a new option "steps" that when
set to true connects the points with horizontal/vertical steps
instead of diagonal lines.
- The legend labelFormatter now passes the series in addition to just
the label (suggestion by Vincent Lemeltier).
- Horizontal bars (based on patch by Jason LeBrun).
- Support for partial bars by specifying a third coordinate, i.e. they
don't have to start from the axis. This can be used to make stacked
bars.
- New option to disable the (grid.show).
- Added pointOffset method for converting a point in data space to an
offset within the placeholder.
- Plugin system: register an init method in the $.flot.plugins array
to get started, see PLUGINS.txt for details on how to write plugins
(it's easy). There are also some extra methods to enable access to
internal state.
- Hooks: you can register functions that are called while Flot is
crunching the data and doing the plot. This can be used to modify
Flot without changing the source, useful for writing plugins. Some
hooks are defined, more are likely to come.
- Threshold plugin: you can set a threshold and a color, and the data
points below that threshold will then get the color. Useful for
marking data below 0, for instance.
- Stack plugin: you can specify a stack key for each series to have
them summed. This is useful for drawing additive/cumulative graphs
with bars and (currently unfilled) lines.
- Crosshairs plugin: trace the mouse position on the axes, enable with
crosshair: { mode: "x"} (see the new tracking example for a use).
- Image plugin: plot prerendered images.
- Navigation plugin for panning and zooming a plot.
- More configurable grid.
- Axis transformation support, useful for non-linear plots, e.g. log
axes and compressed time axes (like omitting weekends).
- Support for twelve-hour date formatting (patch by Forrest Aldridge).
- The color parsing code in Flot has been cleaned up and split out so
it's now available as a separate jQuery plugin. It's included inline
in the Flot source to make dependency managing easier. This also
makes it really easy to use the color helpers in Flot plugins.
Bug fixes:
- Fixed two corner-case bugs when drawing filled curves (report and
analysis by Joshua Varner).
- Fix auto-adjustment code when setting min to 0 for an axis where the
dataset is completely flat on that axis (report by chovy).
- Fixed a bug with passing in data from getData to setData when the
secondary axes are used (issue 65, reported by nperelman).
- Fixed so that it is possible to turn lines off when no other chart
type is shown (based on problem reported by Glenn Vanderburg), and
fixed so that setting lineWidth to 0 also hides the shadow (based on
problem reported by Sergio Nunes).
- Updated mousemove position expression to the latest from jQuery (bug
reported by meyuchas).
- Use CSS borders instead of background in legend (fix printing issue 25
and 45).
- Explicitly convert axis min/max to numbers.
- Fixed a bug with drawing marking lines with different colors
(reported by Khurram).
- Fixed a bug with returning y2 values in the selection event (fix
by exists, issue 75).
- Only set position relative on placeholder if it hasn't already a
position different from static (reported by kyberneticist, issue 95).
- Don't round markings to prevent sub-pixel problems (reported by Dan
Lipsitt).
- Make the grid border act similarly to a regular CSS border, i.e.
prevent it from overlapping the plot itself. This also fixes a
problem with anti-aliasing when the width is 1 pixel (reported by
Anthony Ettinger).
- Imported version 3 of excanvas and fixed two issues with the newer
version. Hopefully, this will make Flot work with IE8 (nudge by
Fabien Menager, further analysis by Booink, issue 133).
- Changed the shadow code for lines to hopefully look a bit better
with vertical lines.
- Round tick positions to avoid possible problems with fractions
(suggestion by Fred, issue 130).
- Made the heuristic for determining how many ticks to aim for a bit
smarter.
- Fix for uneven axis margins (report and patch by Paul Kienzle) and
snapping to ticks (concurrent report and patch by lifthrasiir).
- Fixed bug with slicing in findNearbyItems (patch by zollman).
- Make heuristic for x axis label widths more dynamic (patch by
rickinhethuis).
- Make sure points on top take precedence when finding nearby points
when hovering (reported by didroe, issue 224).
Flot 0.5
--------
Backwards API change summary: Timestamps are now in UTC. Also
"selected" event -> becomes "plotselected" with new data, the
parameters for setSelection are now different (but backwards
compatibility hooks are in place), coloredAreas becomes markings with
a new interface (but backwards compatibility hooks are in place).
Interactivity: added a new "plothover" event and this and the
"plotclick" event now returns the closest data item (based on patch by
/david, patch by Mark Byers for bar support). See the revamped
"interacting with the data" example for some hints on what you can do.
Highlighting: you can now highlight points and datapoints are
autohighlighted when you hover over them (if hovering is turned on).
Support for dual axis has been added (based on patch by someone who's
annoyed and /david). For each data series you can specify which axes
it belongs to, and there are two more axes, x2axis and y2axis, to
customize. This affects the "selected" event which has been renamed to
"plotselected" and spews out { xaxis: { from: -10, to: 20 } ... },
setSelection in which the parameters are on a new form (backwards
compatible hooks are in place so old code shouldn't break) and
markings (formerly coloredAreas).
Timestamps in time mode are now displayed according to
UTC instead of the time zone of the visitor. This affects the way the
timestamps should be input; you'll probably have to offset the
timestamps according to your local time zone. It also affects any
custom date handling code (which basically now should use the
equivalent UTC date mehods, e.g. .setUTCMonth() instead of
.setMonth().
Added support for specifying the size of tick labels (axis.labelWidth,
axis.labelHeight). Useful for specifying a max label size to keep
multiple plots aligned.
Markings, previously coloredAreas, are now specified as ranges on the
axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings
you can now draw horizontal/vertical lines by setting from and to to
the same coordinate (idea from line support patch by by Ryan Funduk).
The "fill" option can now be a number that specifies the opacity of
the fill.
You can now specify a coordinate as null (like [2, null]) and Flot
will take the other coordinate into account when scaling the axes
(based on patch by joebno).
New option for bars "align". Set it to "center" to center the bars on
the value they represent.
setSelection now takes a second parameter which you can use to prevent
the method from firing the "plotselected" handler.
Using the "container" option in legend now overwrites the container
element instead of just appending to it (fixes infinite legend bug,
reported by several people, fix by Brad Dewey).
Fixed a bug in calculating spacing around the plot (reported by
timothytoe). Fixed a bug in finding max values for all-negative data
sets. Prevent the possibility of eternal looping in tick calculations.
Fixed a bug when borderWidth is set to 0 (reported by
Rob/sanchothefat). Fixed a bug with drawing bars extending below 0
(reported by James Hewitt, patch by Ryan Funduk). Fixed a
bug with line widths of bars (reported by MikeM). Fixed a bug with
'nw' and 'sw' legend positions. Improved the handling of axis
auto-scaling with bars. Fixed a bug with multi-line x-axis tick
labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
Flot 0.4
--------
API changes: deprecated axis.noTicks in favor of just specifying the
number as axis.ticks. So "xaxis: { noTicks: 10 }" becomes
"xaxis: { ticks: 10 }"
Time series support. Specify axis.mode: "time", put in Javascript
timestamps as data, and Flot will automatically spit out sensible
ticks. Take a look at the two new examples. The format can be
customized with axis.timeformat and axis.monthNames, or if that fails
with axis.tickFormatter.
Support for colored background areas via grid.coloredAreas. Specify an
array of { x1, y1, x2, y2 } objects or a function that returns these
given { xmin, xmax, ymin, ymax }.
More members on the plot object (report by Chris Davies and others).
"getData" for inspecting the assigned settings on data series (e.g.
color) and "setData", "setupGrid" and "draw" for updating the contents
without a total replot.
The default number of ticks to aim for is now dependent on the size of
the plot in pixels. Support for customizing tick interval sizes
directly with axis.minTickSize and axis.tickSize.
Cleaned up the automatic axis scaling algorithm and fixed how it
interacts with ticks. Also fixed a couple of tick-related corner case
bugs (one reported by mainstreetmark, another reported by timothytoe).
The option axis.tickFormatter now takes a function with two
parameters, the second parameter is an optional object with
information about the axis. It has min, max, tickDecimals, tickSize.
Added support for segmented lines (based on patch from Michael
MacDonald) and for ignoring null and bad values (suggestion from Nick
Konidaris and joshwaihi).
Added support for changing the border width (joebno and safoo).
Label colors can be changed via CSS by selecting the tickLabel class.
Fixed a bug in handling single-item bar series (reported by Emil
Filipov). Fixed erratic behaviour when interacting with the plot
with IE 7 (reported by Lau Bech Lauritzen). Prevent IE/Safari text
selection when selecting stuff on the canvas.
Flot 0.3
--------
This is mostly a quick-fix release because jquery.js wasn't included
in the previous zip/tarball.
Support clicking on the plot. Turn it on with grid: { clickable: true },
then you get a "plotclick" event on the graph placeholder with the
position in units of the plot.
Fixed a bug in dealing with data where min = max, thanks to Michael
Messinides.
Include jquery.js in the zip/tarball.
Flot 0.2
--------
Added support for putting a background behind the default legend. The
default is the partly transparent background color. Added
backgroundColor and backgroundOpacity to the legend options to control
this.
The ticks options can now be a callback function that takes one
parameter, an object with the attributes min and max. The function
should return a ticks array.
Added labelFormatter option in legend, useful for turning the legend
labels into links.
Fixed a couple of bugs.
The API should now be fully documented.
Patch from Guy Fraser to make parts of the code smaller.
API changes: Moved labelMargin option to grid from x/yaxis.
Flot 0.1
--------
First public release.

Writing plugins
---------------
To make a new plugin, create an init function and a set of options (if
needed), stuff it into an object and put it in the $.plot.plugins
array. For example:
function myCoolPluginInit(plot) { plot.coolstring = "Hello!" };
var myCoolOptions = { coolstuff: { show: true } }
$.plot.plugins.push({ init: myCoolPluginInit, options: myCoolOptions });
// now when $.plot is called, the returned object will have the
// attribute "coolstring"
Now, given that the plugin might run in many different places, it's
a good idea to avoid leaking names. We can avoid this by wrapping the
above lines in an anonymous function which we call immediately, like
this: (function () { inner code ... })(). To make it even more robust
in case $ is not bound to jQuery but some other Javascript library, we
can write it as
(function ($) {
// plugin definition
// ...
})(jQuery);
Here is a simple debug plugin which alerts each of the series in the
plot. It has a single option that control whether it is enabled and
how much info to output:
(function ($) {
function init(plot) {
var debugLevel = 1;
function checkDebugEnabled(plot, options) {
if (options.debug) {
debugLevel = options.debug;
plot.hooks.processDatapoints.push(alertSeries);
}
}
function alertSeries(plot, series, datapoints) {
var msg = "series " + series.label;
if (debugLevel > 1)
msg += " with " + series.data.length + " points";
alert(msg);
}
plot.hooks.processOptions.push(checkDebugEnabled);
}
var options = { debug: 0 };
$.plot.plugins.push({
init: init,
options: options,
name: "simpledebug",
version: "0.1"
});
})(jQuery);
We also define "name" and "version". It's not used by Flot, but might
be helpful for other plugins in resolving dependencies.
Put the above in a file named "jquery.flot.debug.js", include it in an
HTML page and then it can be used with:
$.plot($("#placeholder"), [...], { debug: 2 });
This simple plugin illustrates a couple of points:
- It uses the anonymous function trick to avoid name pollution.
- It can be enabled/disabled through an option.
- Variables in the init function can be used to store plot-specific
state between the hooks.
Options guidelines
==================
Plugins should always support appropriate options to enable/disable
them because the plugin user may have several plots on the same page
where only one should use the plugin.
If the plugin needs series-specific options, you can put them in
"series" in the options object, e.g.
var options = {
series: {
downsample: {
algorithm: null,
maxpoints: 1000
}
}
}
Then they will be copied by Flot into each series, providing the
defaults in case the plugin user doesn't specify any. Again, in most
cases it's probably a good idea if the plugin is turned off rather
than on per default, just like most of the powerful features in Flot.
Think hard and long about naming the options. These names are going to
be public API, and code is going to depend on them if the plugin is
successful.

About
-----
Flot is a Javascript plotting library for jQuery. Read more at the
website:
http://code.google.com/p/flot/
Take a look at the examples linked from above, they should give a good
impression of what Flot can do and the source code of the examples is
probably the fastest way to learn how to use Flot.
Installation
------------
Just include the Javascript file after you've included jQuery.
Note that you need to get a version of Excanvas (e.g. the one bundled
with Flot) which is canvas emulation on Internet Explorer. You can
include the excanvas script like this:
<!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.pack.js"></script><![endif]-->
If it's not working on your development IE 6.0, check that it has
support for VML which excanvas is relying on. It appears that some
stripped down versions used for test environments on virtual machines
lack the VML support.
Also note that you need at least jQuery 1.2.6 (but at least jQuery
1.3.2 is recommended for interactive charts because of performance
improvements in event handling).
Basic usage
-----------
Create a placeholder div to put the graph in:
<div id="placeholder"></div>
You need to set the width and height of this div, otherwise the plot
library doesn't know how to scale the graph. You can do it inline like
this:
<div id="placeholder" style="width:600px;height:300px"></div>
You can also do it with an external stylesheet. Make sure that the
placeholder isn't within something with a display:none CSS property -
in that case, Flot has trouble measuring label dimensions which
results in garbled looks and might have trouble measuring the
placeholder dimensions which is fatal (it'll throw an exception).
Then when the div is ready in the DOM, which is usually on document
ready, run the plot function:
$.plot($("#placeholder"), data, options);
Here, data is an array of data series and options is an object with
settings if you want to customize the plot. Take a look at the
examples for some ideas of what to put in or look at the reference
in the file "API.txt". Here's a quick example that'll draw a line from
(0, 0) to (1, 1):
$.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } });
The plot function immediately draws the chart and then returns a plot
object with a couple of methods.
What's with the name?
---------------------
First: it's pronounced with a short o, like "plot". Not like "flawed".
So "Flot" rhymes with "plot".
And if you look up "flot" in a Danish-to-English dictionary, some up
the words that come up are "good-looking", "attractive", "stylish",
"smart", "impressive", "extravagant". One of the main goals with Flot
is pretty looks.

<p>The data is fetched over HTTP, in this case directly from text
files. Usually the URL would point to some web server handler
(e.g. a PHP page or Java/.NET/Python/Ruby on Rails handler) that
extracts it from a database and serializes it to JSON.</p>

<p>With the image plugin, you can plot images. This is for example
useful for getting ticks on complex prerendered visualizations.
Instead of inputting data points, you put in the images and where
their two opposite corners are supposed to be in plot space.</p>
<p>Images represent a little further complication because you need
to make sure they are loaded before you can use them (Flot skips
incomplete images). The plugin comes with a couple of helpers
for doing that.</p>

<p>With the navigate plugin it is easy to add panning and zooming.
Drag to pan, double click to zoom (or use the mouse scrollwheel).</p>
<p>The plugin fires events (useful for synchronizing several
plots) and adds a couple of public methods so you can easily build
a little user interface around it, like the little buttons at the
top right in the plot.</p>

age in years (source: <a href="http://www.cdc.gov/nchs/data/nhsr/nhsr010.pdf">CDC</a>).
The 15%-85%, 25%-75% and 50% percentiles are indicated.</p>
<p>For each point of a filled curve, you can specify an arbitrary
bottom. As this example illustrates, this can be useful for
plotting percentiles. If you have the data sets available without
appropriate fill bottoms, you can use the fillbetween plugin to
compute the data point bottoms automatically.</p>

<h2>Pie Options</h2>
<ul class="options">
<li style="border-bottom: 1px dotted #ccc;"><b>option:</b> <i>default value</i> - Description of option</li>
<li><b>show:</b> <i>false</i> - Enable the plugin and draw as a pie.</li>
<li><b>radius:</b> <i>'auto'</i> - Sets the radius of the pie. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length. If set to 'auto', it will be set to 1 if the legend is enabled and 3/4 if not.</li>
<li><b>innerRadius:</b> <i>0</i> - Sets the radius of the donut hole. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the radius, otherwise it will use the value as a direct pixel length.</li>
<li><b>startAngle:</b> <i>3/2</i> - Factor of PI used for the starting angle (in radians) It can range between 0 and 2 (where 0 and 2 have the same result).</li>
<li><b>tilt:</b> <i>1</i> - Percentage of tilt ranging from 0 and 1, where 1 has no change (fully vertical) and 0 is completely flat (fully horizontal -- in which case nothing actually gets drawn).</li>
<li><b>offset:</b> <ul>
<li><b>top:</b> <i>0</i> - Pixel distance to move the pie up and down (relative to the center).</li>
<li><b>left:</b> <i>'auto'</i> - Pixel distance to move the pie left and right (relative to the center).</li>
</ul>
<li><b>stroke:</b> <ul>
<li><b>color:</b> <i>'#FFF'</i> - Color of the border of each slice. Hexadecimal color definitions are prefered (other formats may or may not work).</li>
<li><b>width:</b> <i>1</i> - Pixel width of the border of each slice.</li>
</ul>
<li><b>label:</b> <ul>
<li><b>show:</b> <i>'auto'</i> - Enable/Disable the labels. This can be set to true, false, or 'auto'. When set to 'auto', it will be set to false if the legend is enabled and true if not.</li>
<li><b>radius:</b> <i>1</i> - Sets the radius at which to place the labels. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length.</li>
<li><b>threshold:</b> <i>0</i> - Hides the labels of any pie slice that is smaller than the specified percentage (ranging from 0 to 1) i.e. a value of '0.03' will hide all slices 3% or less of the total.</li>
<li><b>formatter:</b> <i>[function]</i> - This function specifies how the positioned labels should be formatted, and is applied after the legend's labelFormatter function. The labels can also still be styled using the class "pieLabel" (i.e. ".pieLabel" or "#graph1 .pieLabel").</li>
<li><b>radius:</b> <i>1</i> - Sets the radius at which to place the labels. If value is between 0 and 1 (inclusive) then it will use that as a percentage of the available space (size of the container), otherwise it will use the value as a direct pixel length.</li>

<li><b>threshold:</b> <i>0</i> - Combines all slices that are smaller than the specified percentage (ranging from 0 to 1) i.e. a value of '0.03' will combine all slices 3% or less into one slice).</li>
<li><b>color:</b> <i>null</i> - Backgound color of the positioned labels. If null, the plugin will automatically use the color of the first slice to be combined.</li>
<li><b>label:</b> <i>'Other'</i> - Label text for the combined slice.</li>
</ul>
<li><b>highlight:</b> <ul>
<li><b>opacity:</b> <i>0.5</i> - Opacity of the highlight overlay on top of the current pie slice. Currently this just uses a white overlay, but support for changing the color of the overlay will also be added at a later date.

<h2>Changes/Features</h2>
<ul>
<li style="list-style: none;"><i>v1.0 - November 20th, 2009 - Brian Medendorp</i></li>
<li>The pie plug-in is now part of the Flot repository! This should make it a lot easier to deal with.</li>
<li>Added a new option (innerRadius) to add a "donut hole" to the center of the pie, based on comtributions from Anthony Aragues. I was a little reluctant to add this feature because it doesn't work very well with the shadow created for the tilted pie, but figured it was worthwhile for non-tilted pies. Also, excanvas apparently doesn't support compositing, so it will fall back to using the stroke color to fill in the center (but I recommend setting the stroke color to the background color anyway).</li>
<li>Changed the lineJoin for the border of the pie slices to use the 'round' option. This should make the center of the pie look better, particularly when there are numerous thin slices.</li>
<li>Included a bug fix submitted by btburnett3 to display a slightly smaller slice in the event that the slice is 100% and being rendered with Internet Explorer. I haven't experienced this bug myself, but it doesn't seem to hurt anything so I've included it.</li>
<li>The tilt value is now used when calculating the maximum radius of the pie in relation to the height of the container. This should prevent the pie from being smaller than it needed to in some cases, as well as reducing the amount of extra white space generated above and below the pie.</li>
<li><b>Hover and Click functionality are now availabe!</b><ul>
<li>Thanks to btburnett3 for the original hover functionality and Anthony Aragues for the modification that makes it compatable with excanvas, this was a huge help!</li>
<li>Added a new option (highlight opacity) to modify the highlight created when mousing over a slice. Currently this just uses a white overlay, but an option to change the hightlight color will be added when the appropriate functionality becomes available.
<li>I had a major setback that required me to practically rebuild the hover/click events from scratch one piece at a time (I discovered that it only worked with a single pie on a page at a time), but the end result ended up being virtually identical to the original, so I'm not quite sure what exactly made it work.</li>
<li><span style="color: red;">Warning:</span> There are some minor issues with using this functionality in conjuction with some of the other more advanced features (tilt and donut). When using a donut hole, the inner portion still triggers the events even though that portion of the pie is no longer visible. When tilted, the interactive portions still use the original, untilted version of the pie when determining mouse position (this is because the isPointInPath function apparently doesn't work with transformations), however hover and click both work this way, so the appropriate slice is still highlighted when clicking, and it isn't as noticable of a problem.</li>
</ul></li>
<li>Included a bug fix submitted by Xavi Ivars to fix array issues when other javascript libraries are included in addition to jQuery</li>
<br/>
<li style="list-style: none;"><i>v0.4 - July 1st, 2009 - Brian Medendorp</i></li>
<li>Each series will now be shown in the legend, even if it's value is zero. The series will not get a positioned label because it will overlap with the other labels present and often makes them unreadable.</li>
<li>Data can now be passed in using the standard Flot method using an array of datapoints, the pie plugin will simply use the first y-value that it finds for each series in this case. The plugin uses this datastructure internally, but you can still use the old method of passing in a single numerical value for each series (the plugin will convert it as necessary). This should make it easier to transition from other types of graphs (such as a stacked bar graph) to a pie.</li>
<li>The pie can now be tilted at an angle with a new "tilt" option. Acceptable values range from 0-1, where 1 has no change (fully vertical) and 0 is completely flat (fully horizontal -- in which case nothing actually gets drawn). If the plugin determines that it will fit within the canvas, a drop shadow will be drawn under the tilted pie (this also requires a tilt value of 0.8 or less).</li>
<br/>
<li style="list-style: none;"><i>v0.3.2 - June 25th, 2009 - Brian Medendorp</i></li>
<li>Fixed a bug that was causing the pie to be shifted too far left or right when the legend is showing in some cases.</li>
<br/>
<li style="list-style: none;"><i>v0.3.1 - June 24th, 2009 - Brian Medendorp</i></li>
<li>Fixed a bug that was causing nothing to be drawn and generating a javascript error if any of the data values were set to zero.</li>
<br/>
<li style="list-style: none;"><i>v0.3 - June 23rd, 2009 - Brian Medendorp</i></li>
<li>The legend now works without any modifications! Because of changes made to flot and the plugin system (thanks Ole Laursen!) I was able to simplify a number of things and am now able to use the legend without the direct access hack that was required in the previous version.</li>
<br/>
<li style="list-style: none;"><i>v0.2 - June 22nd, 2009 - Brian Medendorp</i></li>
<li>The legend now works but only if you make the necessary changes to jquery.flot.js. Because of this, I changed the default values for pie.radius and pie.label.show to new 'auto' settings that change the default behavior of the size and labels depending on whether the legend functionality is available or not.</li>
<br/>
<li style="list-style: none;"><i>v0.1 - June 18th, 2009 - Brian Medendorp</i></li>
<li>Rewrote the entire pie code into a flot plugin (since that is now an option), so it should be much easier to use and the code is cleaned up a bit. However, the (standard flot) legend is no longer available because the only way to prevent the grid lines from being displayed also prevents the legend from being displayed. Hopefully this can be fixed at a later date.</li>
<li>Restructured and combined some of the options. It should be much easier to deal with now.</li>
<li>Added the ability to change the starting point of the pie (still defaults to the top).</li>
<li>Modified the default options to show the labels to compensate for the lack of a legend.</li>
<li>Modified this page to use a random dataset. <span style="color: red">Note: you may need to refresh the page to see the effects of some of the examples.</span></li>
<br/>
<li style="list-style: none;"><i>May 21st, 2009 - Brian Medendorp</i></li>
<li>Merged original pie modifications by Sergey Nosenko into the latest SVN version <i>(as of May 15th, 2009)</i> so that it will work with ie8.</li>
<li>Pie graph will now be centered in the canvas unless moved because of the legend or manually via the options. Additionally it prevents the pie from being moved beyond the edge of the canvas.</li>
<li>Modified the code related to the labelFormatter option to apply flot's legend labelFormatter first. This is so that the labels will be consistent, but still provide extra formatting for the positioned labels (such as adding the percentage value).</li>
<li>Positioned labels now have their backgrounds applied as a seperate element (much like the legend background) so that the opacity value can be set independently from the label itself (foreground). Additionally, the background color defaults to that of the matching slice.</li>
<li>As long as the labelOffset and radiusLimit are not set to hard values, the pie will be shrunk if the labels will extend outside the edge of the canvas</li>
<li>Added new options "radiusLimitFactor" and "radiusLimit" which limits how large the (visual) radius of the pie is in relation to the full radius (as calculated from the canvas dimensions) or a hard-pixel value (respectively). This allows for pushing the labels "outside" the pie.</li>
<li>Added a new option "labelHidePercent" that does not show the positioned labels of slices smaller than the specified percentage. This is to help prevent a bunch of overlapping labels from small slices.</li>
<li>Added a new option "sliceCombinePercent" that combines all slices smaller than the specified percentage into one larger slice. This is to help make the pie more attractive when there are a number of tiny slices. The options "sliceCombineColor" and "sliceCombineLabel" have also been added to change the color and name of the new slice if desired.</li>
<li>Tested in Firefox (3.0.10, 3.5b4), Internet Explorer (6.0.2900, 7.0.5730, 8.0.6001), Chrome (1.0.154), Opera (9.64), and Safari (3.1.1, 4 beta 5528.16).

select on one axis. Try left-click and drag on the plot above
where selection on the x axis is enabled.</p>
<p>You selected: <span id="selection"></span></p>

<h1>Flot Examples</h1>
<div id="placeholder" style="width:600px;height:300px;"></div>
<p>Example of loading data dynamically with AJAX. Percentage change in GDP (source: <a href="http://epp.eurostat.ec.europa.eu/tgm/table.do?tab=table&init=1&plugin=1&language=en&pcode=tsieb020">Eurostat</a>). Click the buttons below.</p>
<p>The data is fetched over HTTP, in this case directly from text
files. Usually the URL would point to some web server handler
(e.g. a PHP page or Java/.NET/Python/Ruby on Rails handler) that
extracts it from a database and serializes it to JSON.</p>
<p>
<input class="fetchSeries" type="button" value="First dataset"> -
<a href="data-eu-gdp-growth.json">data</a> -
<span></span>
</p>
<p>
<input class="fetchSeries" type="button" value="Second dataset"> -
<a href="data-japan-gdp-growth.json">data</a> -
<span></span>
</p>
<p>
<input class="fetchSeries" type="button" value="Third dataset"> -
<a href="data-usa-gdp-growth.json">data</a> -
<span></span>
</p>
<p>If you combine AJAX with setTimeout, you can poll the server
for new data.</p>

<p>Flot has support for simple background decorations such as
lines and rectangles. They can be useful for marking up certain
areas. You can easily add any HTML you need with standard DOM
manipulation, e.g. for labels. For drawing custom shapes there is
also direct access to the canvas.</p>
<script id="source" language="javascript" type="text/javascript">
$(function () {
// generate a dataset
var d1 = [];
