Hello,
I basically have a Chi-Squared distribution that is dependent on 3
variables.
eg. X2(x, y, z)
What I would like to do is be able to plot the chi-squared + 1 surface in
3-dimensions.
eg. I would like to have the three axes as x, y and z. and then have a
surface (its going to look like a closed blob effectively) that maps the
chi-squared plus one surface.
I have no idea how to do this though. Is it possible? any ideas?

I think matplotlib is relatively limited in its 3D capabilities. I would suggest trying Mayavi2 with a contour3d[1] or a volume[2,3]. Look here[4] for many examples.
