@Tyberius I wonder why "How to plot a Gaussian cube file with python/matplotlib" is so hard to get answered? It's a brand new user so I was hoping their question would get answered quite immediately (leaving them with a very positive impression of the site). Isn't Gaussian used by quite a large number of people, and python/matplotlib used even more? Unfortunately I don't have much experience with Gaussian (I used MOLPRO and CFOUR much more) or Python (I used MATLAB much more).
