I am trying to make the chart attached, and there are two main problems.
1. Is it possible to position the labels? The defaults have them overlapping (this is also clear on the demo chart at http://demos.telerik.com/jsp-ui/radar-charts/index)
2. Is it possible to add background colours per the attached? These are basically for grouping. I tried adding another series, but as a radarArea it doesn't apply the colours except to the tooltips (and overlaps the blue area of the first series), and as a radarColumn chart is conceals everything else (even if that is the first series).
Can you help me?
Note: I have no idea why the percentages are backwards in the screenshot - please disregard that.
