A basic line chart

A simple black and white Line chart with Trace2- defaults have been changed though so there is some configuration required.

[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: [4,5,5,6,6,7,4,5,6,8,8,9,15,16,24,25, null, null],
        options: {
            numxticks: 0,
            numyticks: 0,
            backgroundGrid: false,
            colors: ['black'],
            linewidth: 5,
            hmargin: 5,
            ylabels: false,
            shadow: false,
            tickmarks: null
        }
    }).trace2();
</script>
