I like to avoid fink unless I absolutely have to use it -- it ends up 
installing a whole bunch of packages that I already have elsewhere on 
my machine, thereby creating the need to maintain multiple 
installations of the same package.

... I'm not sure why I'd want to use gtk instead of wx anyhow, given 
the choice.

I'm trying to keep my plotting in a separate module from everything 
else, so that I don't have to make changes all over the place when I 
change my plotting code. For example, plot_histogram() can be  called 
from any other module without knowing how the plot is implemented. If I 
have to call show() from each module that uses the plotting module, it 
will start to get messy. Outside of the Plot module, the rest of my 
code shouldn't have to know anything about matplotlib. So, I'd like to 
be able to gererate and save a plot, then move on to the next piece of 
code. I'm trying to use your package in place of scipy, which is what I 
have been using to generate plots up until now; hopefully I can make it 
work.
