A Line chart showing students who left and rejoined the school

[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:
    new RGraph.Line({
        data: [
        options: {
            colors: ['red', 'blue'],
            tickmarksStyle: ['filledsquare', 'filledcircle'],
            tickmarksSize: 7,
            linewidth: 5,
            shadow: false,
            backgroundGridHlinesCount: 6,
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            hmargin: 30,
            xaxisLabels: ['1996','1997','1998','1999','2000','2001'],
            yaxisScaleMax: 600,
            yaxisLabelsCount: 6,
            yaxisTickmarksCount: 6,
            marginLeft: 50,
