[Matplotlib-users] Script two planes

It's been a long time since I had to do surface fitting to data (let alone
display of such), so I did a quick search and found an answer for you that
not only finds best-fit plane, but also displays the input points with a
wireframe to represent the plane, and all of that in a rotating 3D display.
The solution uses matplotlib.pytplot.plot_wireframe() and Axes3D (it
imports it, but I don't see it get used).
Here's the answer, from stackexchange, of course:
