It “infects” the global namespace with all matplotlib and numpy functions. It breaks two entries in the famous “Zen of Python”: Explicit is better than implicit.

I am also a huge fan of Python, so I thought to myself: can I combine these things? Well until now I didnt think you could. Matplotlibs contour plots require evenly spaced x and y points with z points to match. This is until I found a way
