A stacked SVG Bipolar chart

A pretty standard stacked Bipolar chart. It has a title, subtitle but no labels are defined.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.bipolar.js"></script>
Put this where you want the chart to show up:
<div style="padding: 15px">
    <div style="width: 600px; height: 500px" id="chart-container"></div>
</div>
This is the code that generates the chart:
<script>
    new RGraph.SVG.Bipolar({
        id: 'cc',
        left: [[4,3,5],[8,6,5],[4,8,8],[4,4,4],[6,5,8]],
        right: [[9,15,8],[4,3,8],[26,5,15],[3,16,24],[12,16,18]],
        options: {
            grouping: 'stacked',
            vmargin: 25,
            title: 'A stacked Bipolar example chart',
            titleSubtitle: 'A subtitle to go along with the title',
            marginTop: 50
        }
    }).draw();
</script>
