An example of a Vertical Progress bar 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.drawing.rect.js"></script>
<script src="RGraph.vprogress.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="250" height="500">
    [No canvas support]
This is the code that generates the chart:
    new RGraph.VProgress({
        id: 'cvs',
        min: 0,
        max: 100,
        value: [10,12,13,16,18],
        options: {
            textSize: 12,
            key: ['Jim','Jack','Joseph','Jane', 'Jimmy'],
            keyInteractive: true,
            keyPositionX: 140,
            keyPositionY: 20,
            marginRight: 150
