A Bar chart combined with a Line chart
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>
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, 5.4],
options: {
marginBottom: 40,
xaxisPosition: 'center',
backgroundGridVlinesCount: 0,
backgroundGridHlinesCount: 8,
yaxisLabelsCount: 8,
yaxisTickmarksCount: 8,
colorsStroke: 'rgba(0,0,0,0)',
xaxisLabels: [
'Q1\r\n2009','Q2\r\n2009','Q3\r\n2009','Q4\r\n2009',
'Q1\r\n2010','Q2\r\n2010','Q3\r\n2010','Q4\r\n2010',
'Q1\r\n2011','Q2\r\n2011','Q3\r\n2011','Q4\r\n2011',
'Q1\r\n2012','Q2\r\n2012','Q3\r\n2012','Q4\r\n2012'
],
yaxisScaleMax: 8
}
});
//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],
// colors: ['#000'],
// xaxisPosition: 'center',
// yaxisScaleMax: 8,
// linewidth: 4,
// tickmarksStyle: null
//});
line = new RGraph.Line({
id: 'cvs',
data: [-2,-1,0.5,2.2,2.8,3.2,4.7,5.7,5.9,4.5,6.5,7.5,6.8,5.8,5.8,6.0],
options: {
colors: ['#000'],
xaxisPosition: 'center',
yaxisScaleMax: 8,
linewidth: 4,
tickmarksStyle: null
}
});
combo = new RGraph.CombinedChart(bar, line)
.draw();
