An offset X axis Line chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.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.Line({
        id: 'cvs',
        data: [19,13,5,-4,-6,-1,3],
        options: {
            hmargin: 10,
            marginBottom: 125,
            linewidth: 2,
            backgroundGridHlinesCount: 6,
            yaxisLabelsCount: 3,
            colors: ['gray'],
            yaxisScaleMax: 20,
            yaxisScaleMin: -10,
            yaxisTickmarksCount: 3,
            yaxisScaleUnitsPost: '% ',
            marginLeft: 50,
            xaxisLabels: ['Carl','Vera','Hoolio','Indigo','Pete','Louise','Jim']
        }
    }).draw();
</script>
