Hmm, I find your post a little confusing.  You mention that you notice
0.90 is out and yet you test on 0.87.7.... This bug was fixed in the
0.90 release.  Do you not have access to 0.90 for some reason, ie you
need a binary that hasn't been built?

Hi

Saving a semilogy plot using the odf backend the exponents come out 
wrong. As can be seen in the attached png file pdf-backend.png the 
exponents are printed as a subscript and also with the lowest value at 
the top of the axis, 10e-3 is at the top and 10e3 is at the bottom. See 
t-pngbackend.png for the behaviour I get with a png backend.

Looking at the source for the pdf-backend I also saw that it contains a 
mix of space and tabs for indentation.

Keep up the good work, I'm looking forward to using 0.9 when the win32 
binary is out.

hi

the recent announcment of matplotlib 0.9 made me look through my notes 
on bugs I've found. With 0.87.7 pylab.axis does not support setting of 
axislimits, I have attached a crash report. I think the problem is a 
change in the handling of kwargs in set_*lim in axes.py.
