matplotlib in python

[gpwood]

Recently I have started using matplotlib for plotting figures in python through some inline functions. If you want to save the figures without viewing them through an X11 session you would usually set an option in a .matplotlibrc file or use the directive matplotlib.use('Agg') at the start of the code. However, I'm finding that when used inline this is ignored and the code tries to display the image. This is a problem when computing on a server which is headless as the code falls over complaining with TclError: couldn't connect to display. Does anyone know how to force the inline code to be headless?
