If so... I suppose if you were really determined you could do this in DPlot, with each radial grid line being a separate curve on a normal XY plot. But to do this you'd basically be using DPlot as a paint program, not a graph program, and there must almost certainly be a better way to do this in another program. Excel does radar plots, though I've never had a need for one personally and can't vouch for how well that works.
