Re: [Matplotlib-users] BUG: Log axes are upside down with PDF output...

2008-03-21 Thread Michael Droettboom 
I vaguely recall a bug whereby mathtext on PDF was upside down (because 
the direction of the y-axis was not being inverted)... but I can't find 
the bug report.

It does seem to work in 0.90.1 and 0.91.2 (on Linux at least).  Are you 
able to upgrade?

Cheers,
Mike

 Hi. I'm making scientific graphs again, so i just got back on this 
 mailing list after a two year hiatus.

 I am using:
 matplotlib-0.90.0-py2.5-macosx-10.4-fat.egg

 Here is a simple program:

 #!/usr/bin/python
 #
 # Do our plots with matplotlib

 import matplotlib
 matplotlib.use('Agg')
 from pylab import *

 fig = figure(num=1,figsize=(6.5,4))
 ax = fig.add_axes([.15,.3,.8,.65])
 ax.set_title(Why is the Y axes upside down?)
 ax.set_yscale('log')
 ax.set_ylabel('Queries per second')

 ax.bar(1,1000,.5,color='r')
 ax.bar(2,5000,.5,color='b')
 ax.bar(3,55000,.5,color='g')

 fig.savefig(broken_log_demo.png)

 Here is the plot with a PNG:



 




 Well, that looks good.

 But here is the plot when I change the type to PDF:




 Notice the the axes are reversed.

Hm.

On my Linux box, Well, easy_install should upgrade me to 91.2, but  
won't build because ft2build.h is missing...?  Apparently that's part  
of freetype v2, which I have installed...

On my Mac, easy_install says that matplotlib 0.87.7 is the active  
version and the best version.

I guess I can't easy install...
