A Bar chart combined with a Line chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.effects.js"></script>
<script src="RGraph.line.js"></script>
<script src="RGraph.bar.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>
    window.onload = function ()
    {
        var bar = new RGraph.Bar({
            id: 'cvs',
            data: [-2.25,-1.8,0.1,1.95,2.2,2.8,4.3,5.7,6,4.3,5.5,6.5,6.45,5.5,5.4],

                ],
                ymax: 8,
                textAccessible: true
            }
        })



        //var line = new RGraph.Line({

        //    ymax: 8,
        //    linewidth: 4,
        //    tickmarks: null
        //})


        var line = new RGraph.Line({
            id: 'cvs',
            data: [-2,-1,0.5,2.2,2.8,3.2,4.7,5.7,5.9,4.5,6.5,7.5,6.8,5.8,5.8],

            }
        })


        var combo = new RGraph.CombinedChart(bar, line)
            .draw();
    };
