Incorrect Plot with matplotlib.axes3d :: Scatter3D

Hi,

I was able to make Scatter3D erroneously shift its plot down by 0.2. I
have no idea why this happened but I can reproduce it.

Basically I have data ranging from 0.0 to -1.0 over an x,y grid but
Scatter3D displays the data shifted down by 0.2!!!

I have included some screen shots of this problem, a python program
which creates it, and the data that I used.

Any help that could be given would be much appreciated.
