Hi, I'd very much vote for such a feature, too. It's absolutely not foolproof currently the way it is :(
What I find weird, too, is that while everthing fits on the canvas for PDF output, the left side is cropped for PNG.
Best regards,

I don't mean to bother people with this question again, but has anyone implemented this auto-adjust feature that John was talking about? It would be nice not having to adjust matplotlib.rcParams['figure.subplot.left'] (and friends) in every plot script, or alternatively, through a clever hierarchy of matplotlibrc files.

By the way: kudos to matplotlib in every other respect!
