Right now it is automatically forced to reside in the X-Y plane, but I want it to reside in the X-Z plane. Here is an excerpt from my code:

What version of mpl are you using?  I don't think those kwargs were added until the upcoming release, v1.1.0.  Does the graph look right if you do just contour?

Plus, from the top of my head, I don't think extend3d works for contourf (but I could be wrong).
