How to make flot responsive?

Question

In the following fiddle:

http://jsfiddle.net/jamitzky/9x7aJ/

How can I make the graph's width change if the window width changes?

code:

$(function () {
var d1 = [];
for (var i = 0; i < 14; i += 0.5)
    d1.push([i, Math.sin(i)]);

var d2 = [[0, 3], [4, 8], [8, 5], [9, 13]];

// a null signifies separate line segments
var d3 = [[0, 12], [7, 12], null, [7, 2.5], [12, 2.5]];

$.plot($("#placeholder"), [ d1, d2, d3 ]);
});

Do you need Flot to be responsive to the window size when opened or to resize with the window? – Bedroll

Answer 1

Try something like this:

Flot will auto draw to the container it's in. So if your div is responsive Flot will be responsive.

then all you have to do is redraw the flot if your window resizes:

You can watch to see if the window resizes with:

    window.onresize = function(event) {
    ...
}

(see: JavaScript window resize event)

This works great but in my case you also need to clean the chart everytime. Example code window.onresize = function(event) { plot2.destroy(); //and then plot2 = $.jqplot........} – Immaterial

Also there's a official flot resize plugin

This seems like the much simpler, native solution. I tried to do it manually, similar to the accepted answer, but I had issues presumably because my flot chart was in an angular directive. Using the resize plugin fixed all my issues instantly. – Gamelan

would definitely also recommend upgrading to the latest flot (0.8.3 as of writing), it has some excellent IE8 error fixes, which i had to previously monkey patch the official flot with try-catching – Lapel

Answer 3

Just include jquery.flot.resize.min.js script from https://github.com/flot/flot in your page. It will become responsive.

I had the same problem and the solution was:

<script language="javascript" type="text/javascript" src="http://people.iola.dk/olau/flot/jquery.js"></script>

<script src="./jquery.flot.axislabels.js"></script>

Answer 5

Just use some css. Any modern browser can use (inline, stylesheet):

<div id="chart" style="width: 100%!important"></div>
