An inverted 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="650" height="400">[No canvas support]</canvas>
This is the code that generates the chart:
    new RGraph.Line({
        id: 'cvs',
        data: [-10,-24,51,65,68,99],
        options: {
            marginLeft: 85,
            marginTop: 45,
            outofbounds: true,
            linewidth: 3,
            colors: ['red'],
            yaxisScaleMax: 150,
            yaxisScaleInvert: true,
            tickmarksStyle: null,
            yaxisScaleMin: -50,
            backgroundGridHlinesCount: 4,
            yaxisLabelsCount: 4,
            yaxisTickmarksCount: 4,
            yaxisScaleUnitsPost: 'k  ',
            hmargin: 15,
            spline: true
