An inverted offset X axis Line chart

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:

<script>
    new RGraph.Line({
        id: 'cvs',
        data: [-10,-24,51,65,68,99],
        options: {
            hmargin: 0,
            gutterLeft: 85,
            gutterTop: 45,
            outofbounds: true,
            linewidth: 3,
            colors: ['red'],
            ymax: 150,
            scaleInvert: true,
            tickmarks: null,
            ymin: -50,
            backgroundGridAutofitNumhlines: 4,
            ylabelsCount: 4,
            numyticks: 4,
            unitsPost: 'k  ',
            hmargin: 15,
            spline: true,
            textAccessible: true
        }
    }).draw();
</script>
