Flot is a Javascript plotting library for jQuery. Read more at the website: <http://www.flotcharts.org/>
npm install flot-latesthtml
`
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.
You can also try using [Flashcanvas][flashcanvas], which uses Flash to
do the emulation. Although Flash can be a bit slower to load than VML,
if you've got a lot of points, the Flash version can be much faster
overall. Flot contains some wrapper code for activating Excanvas which
Flashcanvas is compatible with.
You need at least jQuery 1.2.6, but try at least 1.3.2 for interactive
charts because of performance improvements in event handling.
Basic usage ##
Create a placeholder div to put the graph in:
`html
`
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:
`html
`
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:
`js
$.plot($("#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
API reference. Here's a quick example that'll draw a line
from (0, 0) to (1, 1):
`js
$.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } });
