matplotlib does not make plotting 3-D scalar data (like histograms) easy -- in fact, I don’t think it is possible (it can do surface plots, but only of functions of 2 variables; it cannot do surface contours of 3-dimensional functions). numpy can certainly do the histogramming, but the OP is already doing that with cpptraj.
I stumbled upon the Mayavi2 project which looks like it can do this, though.

I’ve never tried it myself, but they have both a GUI interface as well as a Python-scriptable API so you can use it like matplotlib. In any case it appears to be an open source alternative to the functionality in Mathematica and Matlab I described earlier.
Of course, you can always follow Dan’s advice and see if VMD can do the trick (although I don’t know if you can plot volumetric data without first loading a “molecule”, in which case that approach may be challenging).
Good luck,
Jason
