Thought you might want to know that matplotlib now supports the 
sans-serif glyphs in the STIX fonts.  Just set the rcParam 
"mathtext.fontset" to "stixsans".  The results are pretty nice.

Cheers,

I am having a similar problem.  However I can't seem to get matplotlib
to compile at all.  It fails when it can't find png.h.
At the beginning, it says it can find freetype and libpng, but can't
find the appropriate header files.  I have found them here:

/Developer/SDKs/MacOSX10.5.sdk/usr/X11/include

So the question is, how can I/we get matplotlib to use the included
versions of freetype and libpng instead of downloading and compiling
other versions?

Thanks,
Jeremy

I'm attempting to install matplotlib under version 10.5 ("Leopard") of  
the Macintosh operating system.

I had an old installation, via Fink, which broke when I (foolishly)  
upgraded from version 10.4 to version 10.5.

In principle, installing matplotlib under 10.5 should be simple,  
because Leopard already includes all of matplotlib's dependencies:
	Python 2.4 (and 2.5)
	numpy
	libpng
	zlib
	freetype
	
In practice, I seem to be running into trouble with freetype.

I built matplotlib version 0.90.1 from source, and installed it in / 
Library/Python/2.5/site-packages

When I run python2.5 and import pylab, the import looks for freetext. 
6.dylib in /sw/lib/freetype219/lib/libfreetype.6.dylib (i.e. the  
broken Fink installation, incompatable with Leopard) which results in  
a bus error. (My reasons for this assertion are given below.)  There's  
a (presumably Leopard-compatable) version of libfreetype.6.dylib in / 
usr/X11/lib/libfreetype.6.dylib

...so, my problem seems to be, how do I get matplotlib to look for  
libfreetype.6.dylib in the right place?

I have tried changing setup.py Specifically, I've replaced
	'darwin' : ['/sw/lib/freetype2', '/sw/lib/freetype219', '/usr/local',  
'/usr', '/sw'],
with
	'darwin' : ['/usr/X11', '/usr/X11/lib', '/usr/X11/include', '/usr/X11/ 
include/freetype2', '/usr/local','/usr'],
Which does not solve the problem (does not change anything at all, as  
far as I can tell).

I've not been able to locate an explicit reference to the /sw  
directory anywhere else in setupext.py, or in setup.py

APPENDIX:  why am I convinced that pylab is looking for freetype. 
6.dylib in /sw/lib/freetype219/lib/  ?

First, when I get the bus error, a window pops up saying that Python's  
"unexpected quit" (=crash) may be due to "freetype.6.dylib"

Second, when I click the "report" button in this window, I see many  
pages of debugging info which I don't know how to interpret, but which  
includes this line:
	0x1226000 -  0x1279ff3 +libfreetype.6.dylib ??? (???) /sw/lib/ 
freetype219/lib/libfreetype.6.dylib
	
Third, when I temporarily remove the entire /sw/lib/freetype219  
directory from /sw/lib then run python2.5 and import pylab, I no  
longer get a bus error, but I *do* now get *this* error:
	ImportError: dlopen(/Library/Python/2.5/site-packages/matplotlib/ 
ft2font.so, 2): Library not loaded: /sw/lib/freetype219/lib/ 
libfreetype.6.dylib
   Referenced from: /Library/Python/2.5/site-packages/matplotlib/ 
ft2font.so
   Reason: image not found

I am going to try some monkey business along the lines of
	ln /usr/X11/lib/libfreetype.6.dylib /sw/lib/freetype219/lib/ 
libfreetype.6.dylib
and will let you know the results.  However, even if that works, it's  
a heinous kluge, and probably fragile, too.
