Hi, I am slowly making move to mac, but I still have some worries. As I am preparing to migrate my main work computer (physics research) I am trying to identify replacement software for my graphing needs. I need to be able to produce 2d and 3d, publication-quality plots for posters and paper publications (something similar to Origin). Since I am using Linux over past couple of years I got more-less used to gnuplot which works well, but it's not too user friendly (no GUI). I would prefer open-source, gpl-licence, cross-platform software if at all possible (for easy sharing with colleagues who mostly use Wins). I'd like to hear your experience with various pieces of software as well as transition from Win/Linux to OSX. Thanks, Radek ----- edit ----- I'd prefer to avoid Fink since it needs massive XCode installed and I plan to run it on MBA. Is there a way to install gnuplot only?
