I have been using paraview to view wave fronts generated by an Elmerfem Helmholtz solver. I really need a polar plot that shows intensity (sound pressure etc.) vs angle. This is a common plot used in both acoustics and electromagnetic radiation patterns. Is there a way to do this with paraview.

The input file is a .vtu file generated by Elmerfem. I would attach a copy if I could figure out how.
