Attached and also pasted below is an example which creates a 3d figure using polar coordinates rather than the x and y. The solution was created by Armin Moser when I posted a question to the users list. There are currently no examples of polar coordinates in 3D available.
Any objections to adding this to mpl_examples/mplot3d?
