Correction: running it from the command line generates the same problem 
as is seen in the doc build and described above.

JJ,

Thanks for your fast fix of the last problem I reported.

Now that the doc build is trying to run scripts with the __main__ 
conditional, one of the examples it is tripping over is 
make_room_for_ylabel_using_axesgrid.py.

When I try to run it on the command line or in ipython, it displays 
nothing at all.  I suspect that is related to the failure in the doc 
build, but I haven't looked into it at all.  (In the doc build it 
generates a huge traceback ending in
RuntimeError: maximum recursion depth exceeded in __instancecheck__
).

Hi Stan,
this size problem sounds somewhat familiar to me. I had a serious
headache to get the interaction of wx.ScrolledWindow, wx.BoxSizer and
matplotlib.backends.backend_wxagg.FigureCanvasWxAgg right when zooming a
canvas in and out and resizing the window.

I am not sure if it will help you, but I've attached how exactly I set
up the three elements to behave as I wish. Unrelated code is stripped
from the example.

Hope that helps!

Dieter

Now that I'm pre-building all my enlarged interpolated images to scroll
through,  I'm having trouble forcing the figure/FigureCanvas to be the size I
want.

I'm trying: 
fig.set_size_inches(768 / 72.0, 768 / 72.0),  but it ends up the same size as
the default plot.

If the issue is that the GUI window is not changing size, try adding
"forward=True" to the set_size_inches call. 

Developers:

As I was checking this with v. 1.0.1, I noticed that the Qt4Agg and TkAgg
backends are inconsistent in how they set the size of a figure. Here is the
Qt4Agg behavior:

>>> fig = plt.figure(figsize=[6, 4])
>>> print fig.get_size_inches()
[ 6.          3.97916667]
>>> fig.set_size_inches([6, 4], forward=True)
>>> print fig.get_size_inches()
[ 6.      3.4375]

The initial figure size isn't quite right, and the size after set_size_inches
is worse. (Is the resize ignoring the toolbar height?) Here is the TkAgg
behavior:

>>> fig = plt.figure(figsize=[6, 4])
>>> print fig.get_size_inches()
[ 6.125  4.125]
>>> fig.set_size_inches([6, 4], forward=True)
>>> print fig.get_size_inches()
[ 6.          3.64583333]

Again, the initial size is off (due to the window border?), and the resized
size is incorrect (toolbar again?).

The WXAgg backend correctly sets the figure canvas to the desired size:

>>> fig = plt.figure(figsize=[6, 4])
>>> print fig.get_size_inches()
[ 6.  4.]
>>> fig.set_size_inches([6, 4], forward=True)
>>> print fig.get_size_inches()
[ 6.  4.]

I didn't check any other backends.

I didn't see any indication in the master branch that this behavior has
changed since 1.0.1. I didn't find a report for this issue on the tracker;
shall I create one?
