Hi all,
sorry for the quick cross-post, but I know that many mpl users rely on
the ipython -pylab support for interactive work.
This is a call for testing from current SVN of anyone who uses ipython
with the GUI thread support, whether via -pylab or directly via one of
the -Xthread options.

I have never seen any software which dealt with non uniform DPI
settings, although that is always a possibility. And all the displays I
have ever worked on/with have been the same for both H and V. ( I am a

Hi Rich,
bit confused what your asking.
are you looking for the pylab API savefig
http://matplotlib.sourceforge.net/matplotlib.pyplot.html#-savefig
or you asking how to convert your variable+.png into a filename?
is your variable a number?, string?
for count in range(3):
count = count +1

Use string concatenation:
curVar+'.png'
http://docs.python.org/tut/node5.html#SECTION005120
I want to save plots programmatically, using a variable + .png as the
filename. I don't see an example of the proper syntax, and my
trial-and-error approach hasn't yielded a solution, either.
If I want to write
pylab.save(curVar.png)

Dear all,
I have the following data:
X = [0.0, 1.0, 3.0, 6.0, 10.0, 15.0]
Y = [0.0, 1.0, 2.0, 3.0, 4.0, 5.0]
I can plot the X-Y curve without problem.
But is there a way for me to make the xticks spaced
evenly? That is, the distance between 0.0 and 1.0, 1.0

Mike,
In response to your questions, yes, I meant to say MPL version 0.91.2.
I believe the objects were lists and dictionaries, and they appeared to be
related to plotting parameters, such as those found in rcParams.

Also, if you're adventurous, try installing valgrind and running:
valgrind --tool=massif python slicer.py
valgrind --tool=memcheck --leak-check=yes --log-file=slicer_leak python
slicer.py
and send me the output -- (probably off list because they will be large
files).
Cheers,

Use numbers:

Set the dash sequence, sequence of dashes with on off ink in

I'll also give a "blanket" answer to these sorts of gremlins:
Remove the "build" directory in the source tree
Remove site-packages/matplotlib (usually in

Hi,
I'd like to have figure with 3 (or 4) plots having different scales
but sharing the same x-axis.
Basically I want an extension of the twinx command (see, e.g,

however, when saving the fig as an eps file my postscript processor
(ghostscript) can't read the font information included in the eps file
(ps.fonttype 42 in config file).
