A Radial Scatter chart importing CSV data

View the bare-bones version of this demo with any interactive features or animations enabled

Here's a Radial Scatter chart - a circular Scatter chart. It's a variation on the regular Scatter chart that might suit your data better than the traditional style of Scatter. Radial Scatter charts are only available on canvas - not SVG.

Each point has two values - the angle of the point in degrees and the absolute magnitude. If your values for the angle are initially in a relative format then you would need to convert them first. You could do that with the following example code:

arr = [[10,10],[5,10]];
max = 10;
for (var i=0; i<arr.length; i++) {
    arr[i][0] = arr[i][0] / max * 360;

All this snippet does is convert the data to proportional values based on the maximum value in the array - so you would get an array of [360, 180] So one point would be placed on the north axis and the other point would be placed on the south axis.

The only other configuration is the labels being changed from being on all four axes to just the 'north' axis.

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:
<div style="float: right">
    <canvas id="cvs" width="500" height="450">[No canvas support]</canvas>
This is the code that generates the chart - it should be placed AFTER the canvas tag(s):
