A spline Line chart with multiple lines

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.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: [ [4,5,1,6,3,5,2], [7,7,8,6,2,1,1] ],
        options: {
            spline: true,
            linewidth: 3,
            hmargin: 5,
            xaxisLabels: ['Mon','Tue','Wed','Thu','Fri','Sat','Sun'],
            tooltips: [
                'Mon','Tue','Wed','Thu','Fri','Sat','Sun',
                'Mon','Tue','Wed','Thu','Fri','Sat','Sun'
            ],
            highlightStyle: 'halo',
            tickmarksStyle: 'circle'
        }
    }).trace2();
</script>
