I have created a radar chart with three axes, and I would like to make all the lines in the graph curved instead of straight. I havent found a satisfying way to bend all the paths (i.e. the edges of the triangles) in a way that looks homogenous. I can of course use the reshape tool, but then the degree to which each line is curved looks just random. The Envelope distort tool looks promising, but it changes the position of the corners(the anchors) of my graph as well, which is obviously not acceptable. Is there any way to achieve this in an easy and reproducible way? (I need to create several graphs which should be comparable).
note that I am not (necessarily) trying to create perfect circles as shwon on the image below. The goal is rather to go from straight lines to (slightly) curved ones.
