[Matplotlib-users] 'plot' broken on latest svn
Hello,
I've just updated to the latest svn (5063) and now I cannot create a
simple plot. If I just try (in ipython -pylab):
plot(rand(10))
I get:
type 'exceptions.AttributeError': 'module' object has no attribute
'masked_invalid'
The complete traceback is pasted below.
(My numpy version is 1.0.4, which indeed has no 'numpy.ma.masked_invalid'.)
Regards,
Antonio

[Matplotlib-users] failed to save in 'eps' format when I use latex environment
I'm using matplotlib 0.9.12 from ubuntu hardy 8.04.
To take advantage of the LaTeX handling capability in matplotlib,
I've added next two lines in /etc/matplotlib

Then, I tried next test code.
from pylab import *
x = []; y = []

text(0.5, 0.5, r'\begin{align*}x=\alpha\\y=\beta\end{align*}')

Re: [Matplotlib-users] 'plot' broken on latest svn
Antonio,
Thanks for the report. It should be fixed now. Numpy svn has
masked_invalid, so my earlier change worked for me, and I forgot that
ma.masked_invalid is a new addition (and a nice one).

Re: [Matplotlib-users] legend is not properly drawn when a plot is saved in 'pdf' format
This bug seems to be Cairo-backend specific. The Python PDF backend
seems to work fine. Most likely a problem in the Cairo backend and not
Cairo itself, but I haven't dug any further.

[Matplotlib-users] problem with dynamic subplots and wx
Hello, I just upgraded a number of things on my Mac OS X (Tiger) machine, including to the latest version of wx and matplotlib. I found that there is a bug in the display of dynamic plots with subplots. If I change the subplot line in the examples/dynamic_demo_wx.py to: a = self.fig.add_subplot(221) instead of a = self.fig.add_subplot(111) the plot never shows. It works for 111, and for 121, but not 221. Not sure why! It works in interactive mode, in ipython, but not in dynamic plot. Any ideas? thanks, Brian Blais -- Brian Blais [EMAIL PROTECTED] http://web.bryant.edu/~bblais - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

matplotlib. On the other hand, if you can figure out how to make it work in
latex, and can prove that it is a limitation in matplotlib, please let me
know so we can fix it.
