matplotlib-users Mailing List for matplotlib

Hi guys.
I'm just a newbie at matplotlib. I couldn't find the answer on my 
quistion in project's docs.
I've wrote the following code:
from pylab import *
semilogy([1, 5, 2, 3, 1, 6], basey=2)
show()
It works OK but I'd like to see usual decimal numbers instead of 2^0, 
2^1, 2^2 ... on y axis.
How can I do that?
Thnx.

Unfortunately, I can't reproduce this on my machine even with the latest 
stable version of freetype-2.5.3 (which is the same version in Ubuntu 
Gutsy). The Ubuntu/Debian package of freetype has a lot of patches 
applied, and I don't know if they are causing this (but from the looks 
of them, I doubt it).
Can you set debug.verbose to "annoying" and send me the output of your 
matplotlib run? I want to rule out any font-loading problems.
Cheers,
Mike

I can't reproduce this bug on my own machine with SVN head. I suspect 
this is freetype2 related -- that's the library that actually performs 
the rendering of the characters for the Agg backend. The fact the 
humufr saw this after upgrading to Gutsy suggests there might have been 
 change to freetype that is now revealing possibly an incorrect usage 
in matplotlib. Can you please send the version of freetype you are 
using? (pkg-config --modversion freetype2)
My machine has the (fairly old) 2.1.9.
I'm going to try installing the latest freetype and see if I can 
reproduce this bug.
[I believe this is an instance of the same bug that Darren sent me 
off-list.]
Cheers,
Mike
