Individually setting colors for each Radar Chart category label

Normally, there's no option on Radar Chart to color each of the axis labels individually.

The solution comes from applying fill attribute to each label by a few lines of JavaScript code.

We use rendered and resized events to execute the custom code, which gets all category axis labels within the chart using JavaScript function getElementsByClassName() then looks for a color attribute in data to apply it to.

Please note that addClassNames must be enabled in chart config for this to work. Here's more information about applying class names to chart elements.
