A basic SVG Waterfall chart

A demo of a simple waterfall chart. This Waterfall chart shows declining data and has a total column half way through the data too. It also has a key so you can label the differences between up and down columns. There's also a total column at the end which is optional (but is the default).

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.waterfall.js"></script>
Put this where you want the chart to show up:
<div style="width: 900px; height: 300px" id="chart-container"></div>
This is the code that generates the chart:
<script>
    new RGraph.SVG.Waterfall({
        id: 'chart-container',
        data: [100,-5,-9,-8,null,-4,-26,-27],
        options: {
            xaxisLabels: ['Start', 'Monday','Tuesday','Wednesday','Midweek','Thursday','Friday','Saturday','Result'],
            tooltips: ['Start', 'Monday','Tuesday','Wednesday','Midweek','Thursday','Friday','Saturday','Result: 79 sold, 21 remaining'],
            backgroundGridDashed: true
        }
    }).draw();
</script>
