Re: [Matplotlib-users] faq: reducing figure.figsize cuts off labels and tick marks

[Daniel M. <dan...@go...>]

I have slightly modified the example from
http://matplotlib.sourceforge.net/faq/howto_faq.html#automatically-make-room-for-tick-labels
in order to demonstrate what I mean.

It works with the manual string tick labels but not with regular
auto-generated numerical ones.

Maybe someone knows how to fix this? And I *really* think this should
work automatically. As a compromise, maybe an rcParam would help in
order to keep the current dumb behavior...

Thanks in advance,
Daniel
