Hi all,
I am trying to automatically adjust margins with the SVG backend.
The FAQ example :
http://matplotlib.sourceforge.net/doc/html/faq/howto_faq.html#how-do-i-automatically-make-room-for-my-tick-labels
only works with GUI backends.
May it come from get_window_extent() call ?
How could I modify this snipplet so that it works with SVG (or PDF) backends ?
Thank you for your support.
While I don't know much about how callbacks work in matplotlib,
looking at the source code of figure.draw() method, it seems that
call_back functions connected with the "draw_event" are called after a
figure is drawn. Therefore, you need a second draw. My guess is that
this second draw is somehow automagically done in gui backends.
So, a quick and easy solution would be to save the same figure twice.
First one will have a figure before the adjustment, but the second one
will have a figure after the adjustment.
Or, you may create a custom figure class which overrides the draw()
method to adjust the margins before you draw the actual figure.
Attached is an example of such custom figure class. I slightly
modified the original example.

This works as you expected

The solution is nice, I'll go for this one !
I don't feel confident enough yet to look inside the library's code, I
definitely should !
Thank you very much Jae-Joon !
