A Rose chart using the CSV reader
This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.csv.js"></script>
<script src="RGraph.rose.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="350">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
new RGraph.CSV('/sample.csv', function (csv)
{
// Just fetch the first row of the CSV file, starting at the second column
row1 = csv.getRow(0, 1);
row2 = csv.getRow(1, 1);
data = [];
for (var i=0; i<row1.length; i+=1) {
data[i] = [row1[i], row2[i]];
}
new RGraph.Rose({
id: 'cvs',
data: data,
options: {
labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
labelsAxes: 'n',
margin: 3
}
}).draw();
});
</script>
