Dear ALL,
Just a simple (?) question on Matplotlib GUI backends toolbars. The
Matplotlib examples include a nice sample of programmatically adding a
button to a backend toolbar, but I could not find out how to *remove*
one or more of the buttons from the default toolbar. Has it be
sub-classed? BTW
I just saw a similar error when trying to plot some text; in my case,
basemap wasn't involved.
The full error dump:

Dear ALL,
Enclosed is an sample application I put together (partially using
wxGlade) that is a first attempt at providing a working example of a
GUI frontend with wxPython and Matplotlib/Basemap.
The application consists of two panels, separated by a splitter. The
left panel has a notebook with t

Hi,
I have noticed a memory leak when using pylab.pcolor. Here is the code,
fa() and fb() do the same thing. The difference is the size of the array
which is passed to pcolor. With a large array pcolor leaks but not with a
small one.
Cheers,
Ben

But given the vagueness of what I asked, you're right, os.makedirs was
a good suggestion too. Thanks. I think I need to sit down and spend
some quality time with the os module over Thanksgiving holiday...

Dear Robin,
I do agree (although the Python gurus here highly recommend Qt
instead). wxPython is well documented and has *plenty* of exemples
(much of them truly useful).
I have been working hard to developing a scientific desktop
application which uses wxPython for its GUI frontend and
Matplotli
cbook.mkdirs includes a few if-then calls that only make the directory
if it doesn't already exist (in fact it actually calls os.makedirs in
the function), whereas os.makedirs raises an OSError if the folder I
specified already exists. For my purposes, the cbook implementation is
more convenient.

Ah, silly me. I forgot to notice I was using a path variable in the
string I was giving to mlab.save. Part A works just fine when I
account for that. Now that just leaves creating the directory. I like

Hi,
I have a canvas with two subplot.. I want to be able to hide on of the
subplots by pushing a button and letting the remaining subplot fill the
entire canvas.
If I use the set_visible(True) parameter I correctly remove one of the
subplots.. but the remaining subplot does not fill the canvas..
Dear ALL,
In due time, I intend to compile as many suggestions and tips as
possible to eventually create a "How-To" list for the superb Basemap
module, like the very useful one which is on the Matplotlib home page.

Dear Eric,
Thanks for your reply. This is surely not good news -- maybe an
automatic shrinking mechanism could be added in a future version of
Matplotlib (this would be useful not only with maps, but with other
plots as well)?

Hi,
I think matplotlib is a terrific tool, and it is a major component of
the open source toolset that has allowed me to stop using Matlab.
But, whenever it comes to producing publication plots, there are a few
things I always find challenging - and I'm wondering if I'm doing
things wrong.
First
Hello,
It seems to me there is a bug in matplotlib 0.98.3 (or at least a
change from previous version).
>>> matplotlib.cbook.is_scalar('foo')
False
I would expect this to be True (otherwise,
matplotlib.cbook.flatten(['foo']) enters an infinite recursive loop).
It used to be (0.98.0):
