Hi all,
anytime when requesting semilogy() on bar or hist chart, following error
occurs:
File "/usr/lib/python2.5/site-packages/matplotlib-
0.90.0-py2.5-linux-i686.egg/matplotlib/backends/backend_qtagg.py", line 161,

tverts = self.get_transform().seq_xy_tups(verts)
ValueError: Cannot take log of nonpositive value
I am sure that there is no negative value (just some zeros - this could be
the problem)
Anybody have an idea how to solve it?
