hello, I'm tinkering with my matplotlibrc file and the changes are not taking effect. specifically I'm changing the hspace and wspace between subplots... although none other options seem to take effect either. I put the matplotlibrc file in my working directory with my script. I also tried making changes to the matplotlirc file in the installation directory, this didn't work either. should pylab be looking in the working directory for matplotlibrc? If so, what might be a reason changes aren't taking effect?
