A basic stacked SVG Horizontal Bar chart

Here we have an example of a basic Stacked Horizontal Bar chart. There's nothing special about this chart and the background grid horizontal lines have been disabled.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.hbar.js"></script>
Put this where you want the chart to show up:
<div style="padding: 15px">
    <div style="width: 350px; height: 500px" id="chart-container"></div>
</div>
This is the code that generates the chart:
<script>
    new RGraph.SVG.HBar({
        id: 'chart-container',
        data: [[5,4,8],[8,4,6],[6,2,9],[8,8,9],[4,6,3],[8,4,1],[6,5,6]],
        options: {
            grouping: 'stacked',
            yaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            xaxis: false,
            backgroundGridHlines: false,
            backgroundGridBorder: false,
            title: 'A stacked HBar chart',
            vmargin: 10
        }
    }).draw();
</script>
