Line chart with null values

[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: [1059990.29, 90000.97,508116.23, 54790.12, null,null,null],
        options: {
            gutterLeft: 75,
            backgroundGridAutofitNumvlines: 6,
            tickmarks: 'filledcircle',
            ticksize: 5,
            numxticks: 6,
            labels: ['John','Fred','Lucy','John','Luis','Pete','Kevin'],
            colors: ['#c00', 'pink'],
            linewidth: 2,
            shadow: false,
            scaleZerostart: true
        }
    }).draw();
</script>
