TBH I was being lazy and waiting for more information on what specifically 
it could be used for before giving an opinion... the names at least 
suggest they are primarily for numerical calculations etc. and not drawing 
graphics? I wonder do the parts of Pyplot you want to use even use anything
in NumPy? Obviously numerical calculations and that kind of stuff is 
best done in C in the GRASS libraries and modules to make it available 
also for command-line and scripting use. I think that's the main issue 
here, that having NumPy available doesn't result in the GUI having lots of
computational functionality that isn't available in the core of GRASS.

but just my opinion
