Another issue I just ran into: Scaling
There should be another column in the radar chart data set for a max spoke value i.e. each spoke should have it’s own max value
I had a bunch of information I wanted to put on a radar chart and 4 out of 5 pieces of information were 25.0 or below and the fifth was normally around 1,000. The radar chart just looked like a spike on one side. You could not tell what the other values were doing at all. If there was individual scaling for each value that would take care of this issue.
