Another Scatter chart with an offset X axis

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.scatter.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="200">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Scatter({
        id: 'cvs',
        data: [
            [412,-150], [155,-261], [351,41], [455,-291], [121,-55], [89,-111],
            [400,-66], [358,45], [500,-288], [321,-168], [111,45], [436,88]
        ],
        options: {
            xaxisScaleMax: 500,
            labels: ['0-100','101-200','201-300','301-400','401-500'],
            yaxisScaleMin: -300,
            yaxisScaleMax: 100,
            yaxisTickmarksCount: 4,
            yaxisLabelsCount: 4,
            marginLeft: 50,
            backgroundGridVlines: false,
            backgroundGridHlinesCount: 4,
            backgroundGridColor: '#eee',
            backgroundGridBorder: false,
            yaxisScaleUnitsPost: ' %',
            textColor: '#888',
            axesColor: '#999',
            tickmarksStyle: 'circle'
        }
    }).draw();
</script>
