Hello, I am interested in making plots similar to those attached (I have my own date :P). Any recommendations on what software to use? I suppose there are two things I would like it to do (although either one alone would be nice): 1. Create nice radial/polar diagrams with the angles and distances marked nicely. 2. Create a smooth (colored?) density profile, extrapolating from a relatively small finite sample. I frequently use gnuplot, but I cannot find any way of doing anything like this. Also I tried using matplotlib (python stuff) but, similarly, there is no easy/apparent way of doing it :( Thanks!
