A Radial Scatter 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.rscatter.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="500" height="450">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
new RGraph.CSV('/sample.csv', function (csv)
{
// Fetch the two rows of data from the CSV file, starting at the
// second column
var row1 = csv.getRow(0, 1); // First row
var row2 = csv.getRow(1, 1); // Second row
var data = [];
// Now make up some sample points using the data
for (var i=0; i<row1.length; i+=1) {
data.push( [(row1[i] / 10) * 360, row2[i]]);
}
new RGraph.RScatter({
id: 'cvs',
data: data,
options: {
labelsAxes: 'n'
}
}).draw()
});
</script>
