Angus: I'm curious about how you came to this conclusion. It seems like this should be trivial in Basemap, in fact it's exactly what I designed it for. If you send me a sample of your data, I can give you a simple script to plot it with Basemap. -Jeff > I'm also > vaguely aware of some transformation capabilities (that are relatively > new?) in mpl itself, but I'm not sure whether they're useful to me for > polar co-ordinate systems and plot contents, rather than plot > decorations.
