In my radarplot I calculate the mean of certain values which I show on each one of the axes. I would now like to add an errorbar.
My issue is that I cannot rotate the errorbar in the same way the 'normal' points are rotated (using pol2cart). You can see that result in the picture kiviat1.
My idea to work around this was to just add every errorbar as their own plot. You can see that result in kiviat2. As you can see, the errorbar is rotated, but I cannot find a way to have a nice marker that will actually make it look like a regular standard deviation.
I would be glad to get some new solution ideas. I have also attached an example testscript and the radar plot function (lines 227 and following are the ones where the points are plotted).
