An example of a Line chart with an interactive key

The interactive key has been re-implemented as of June 2013 and added to more chart types.

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.key.js"></script>
<script src="RGraph.line.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="600" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var line = new RGraph.Line({
            id: 'cvs',
            data: [
                [4,8,5,5,6,3,5],
                [1,5,2,3,4,5,5],
                [4,8,9,6,9,8,7]
            ],
            options: {
                key: ['Jim','Jack','Joseph'],
                keyInteractive: true,
                linewidth: 3,
                shadow: true,
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                textAccessible: true
            }
        }).draw();
    };
</script>
