A basic VProgress chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.vprogress.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="100" height="400">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.VProgress({
        id: 'cvs',
        min: 0,
        max: 100,
        value: [10,10,10,10],
        options: {
            textAccessible: true,
            margin: 7,
            bevel: true,
            tooltips: ['An example tooltip!','Foo','bar'],
            colors: ['red','yellow','pink','white']
        }
    }).exec(function (obj)
    {
        var background = RGraph.linearGradient(
            obj,
            25,0,obj.canvas.width - 25,0,
            '#ccc','white', 'white', 'white'
        );
        
        obj.set({
            backgroundColor: background
        });
    }).grow();
</script>
