matplotlib-users Mailing List for matplotlib

I am seeing some strange behavior during IPython and vanilla Python 
interactive sessions. My .matplotlibrc is not being respected. I have tried 
making changes to the copy in my home diretory and the one 
in /usr/share/matplotlib. If I run the commands below or do an 
execfile('/home/darren/test.py') from an interactive session, .matplotlibrc 
is not read. If I run the script from the console, .matplotlibrc is read.

I'm on gentoo with either 0.63.0 or the current cvs, python 2.3.3. Has 
anyboody else seen this? 


from matplotlib.matlab import *
a=[1,10,100,1000,10000]
figure(1)
loglog(a,a)
figure(2)
plot(a,a)
show()

Certainly, my example was giving the expected result (i.e. with spacing) in
older versions of matplotlib. If the argument of \rm{} were to be interpreted
as math mode, it would appear as an equation where the variables v, e, r, s, u,
s, s, o, m and e are multiplied together. It doesn't.

Hello!

Just to let you know: Since I am not the only one having trouble with 
mathplotlib and pygtk 2.3.97, I send the message below to the pygtk 
mailing list.

Niklas.
