Re: [Matplotlib-users] Embedding an MPL Canvas/Figure in a PyGTK Container

Thanks for your reply Mike. Looks like fig.add_axes(..) works the best for me for now. If my situation gets worse I will try and look into calls that allocate window area for the figure/canvas in a container. Thanks again! On Mon, Apr 19, 2010 at 6:03 AM, Michael Droettboom wrote: > The probl

The puzzling thing is this: u'C:\\WINDOWS\\Fonts\\HTOWERTI.TTF' It's using a custom font in mathtext. Are you setting the rcParams mathtext.fontset or mathtext.default? That may the culprit, and if not, it's a bug that it's trying to use that font. Mike william ratcliff wrote: > On the plus

There seems no obvious way to change the padding. You may use *set_rgrids* method which takes rpad parameter but you need to specify the tick locations also. Here is a simple function taken from set_rgrids method, that only change the padding. def update_rpads(ax, rpad): angle = ax._r_label1_
