A basic Waterfall chart

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.waterfall.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>
    new RGraph.Waterfall({
        id: 'cvs',
        data: [10,10,5,-2,-5,6,-5],
        options: {
            labels: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday', 'Total'],
            textAccessible: true
        }
    }).draw();
</script>
