A Scatter chart which shows financial information

This Scatter chart shows sample financial data. It looks like it does because there are many datapoints.

[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]
This is the code that generates the chart:
    <// Generate the financial data
    value = 5;
    data  = [];

    for (var i=0; i<365; i+=1) {
        value += RGraph.random(-1, 1);
        value = Math.max(0, value)
        value = Math.min(10, value)

    new RGraph.Scatter({
        id: 'cvs',
        data: data,
        options: {
            yaxisScaleMax: 10,
            xaxisScaleMin: 0,
            xaxisScaleMax: data.length,
            xaxisLabels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
            tickmarksStyle: null,
            line: true,
            lineColors: ['red'],
            yaxisScaleUnitsPre: '$',
            marginTop: 40,
            marginLeft: 40,
            title: 'Sample financial data',
            backgroundGridColor: '#eee',
            backgroundGridVlinesCount: 64,
            backgroundGridHlinesCount: 20,
