For such things, I like R (from http://www.r-project.org), for which 
also exist a few Python interfaces (I use http://rpy.sourceforge.net).  
For communication between Python and R, Python Numeric facilities are 
usable, yet not required.  Moreover, with 3D-accelerated cards or 
simulations thereof, OpenGL tools (see http://rgl.neoscientists.org) 
allow you to interactively wander into your plot, somehow.

The combination is worth.  What may appear as a drawback is the need to 
become acquainted with R, the system and the language.  But if you 
happen to do scientific works, this really is a worth investment.
