Hi Steve,
Not that I know of :-) I think you'll be fine using 65535 in both
cases. I suggest you go ahead and check it in.

When would some of the handles be None? That looks like a bug to
me...

Subject: Marching Squares Algorithm
Dear Mr. Horton:
I am investigating options for creating 2D contour plots for the freely
distributable Matplotlib package (http://matplotlib.sourceforge.net/).
The Matplotlib license requires all the software to be free for
noncommercial and commercial distribution.
I had the idea to try to implement marching squares for this package. =
We
know the marching cubes algorithm is patented, but what about the 2D
marching squares? Can my implementation be used in this freely
distributed package without obtaining a license grant?
Thanks,
Curtis

Hi there,
in the attachment, find a patch for the legend to behave correctly when some 
of the handles are set to None. (In which case the corresponding space is 
just left empty.)
Without this patch, everything is first set up correctly, but then the 
_update_positions routine shifts the items in the legend box around 
incorrectly.
Ciao,
Norbert

I just installed matplotlib-0.63.4 on Mac OSX 10.3, with some 
difficulties i detail (and answer) below.
Using Fink (0.7.1), freetype2 (2.1.3-21), Tk and GTK.
python setup.py install fails because of wrong paths to find freetype2 
ft2build.h. Darwin include paths (in setupext.py) are '/usr/local', 
'/usr', 'sw'. freetype2 include paths are :
 > locate ft2build.h
 > /sw/lib/freetype2/include/ft2build.h
 > /usr/X11R6/include/freetype2/ft2build.h
Once '/usr/X11R6' or '/sw/lib/freetype2' to setupext.py paths for 
Darwin, build process works fine. Agg, GTKAgg, and TkAgg backends are 
available as described in your documentation.
I use matplotlib with ipython (python2.3.3, IPython0.6.3), and GTKAgg 
backend crashes if pygtk (2.0.0 here) is not build with threading. I 
used
 > python setup.py build --enable-threading
Thanks for this great matplotlib product.

Hi there,
another tiny patch: adding **kwargs to the errorbar function and passing them 
through to the internal plot function. This allows arguments like "color" 
used on errorbar.
Ciao,
Nobbi
