You may need to be more precise in describing what you want to do; it is 
far from clear to me from your subject line.

I am not sure precisely what difficulty you are having, but if you are
trying to change the font family for *subsequent* figures after the
user has made their font choice in the dialog, then the rc setting
will work fine.  If you are trying to change an existing figure, then
rc will not help, but findobj will.  findobj recursive searches a
figure for all the objects in contains, and you can filter for object
type.  So you could do something like

import matplotlib.text as text

for t in fig.findobj(text.Text):
    t.set_family(somefamily)

or t.set_fontproperty(someprop), etc...

If you want to keep the font property (size, weight) as is and only
change the file name, the following may work for some cases

  prop = t.get_font_properties()
  prop.set_file(fname)

but this is fairly dangerous (because you could be mixing a monoface
style with a non monospace font family for example) so it is not
recommended.

Thanks for your help.

I have been getting on OK with manual adjustment.

I thought I would point out a similar problem though which I suspect
is the same thing.

If I am using latex tick labels for a bar graph, the tick labels with
superscripts have a lower baseline than tick labels without
superscripts which again looks a little funny.

Cheers

Thanks for your help, it works, but it is very difficult because I want to
show a FontDialog contains all fonts in system to user and change the plot
text (Legend, Label and ex.) font to that.
How may I accomplish that? Is there any way?
