An example of a Line chart with an interactive key

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

[No canvas support]

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>
    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,
            keyPosition: 'margin',
            linewidth: 3,
            shadow: true,
            xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
        }
    }).draw();
</script>
