matplotlib-users Mailing List for matplotlib (Page 13)

I'm trying to get a script to work in batch mode to produce a large number of
plots.  I've got the following sequence of imports in a matplotlib Python
script:

import matplotlib, os, sys
...
if file_ext == 'png' :
    sys.stderr.write('Using PNG output format\n')
    matplotlib.use('agg')
elif file_ext == 'pdf' :
    sys.stderr.write('Using PDF output format\n')
    matplotlib.use('PDF')

from pylab import *

... remainder of plotting code ...

At first this appeared to work without any problems.  I could kick off a job
in background, log off the machine and return later when all the graphs had
been produced.

Now I get this RuntimeError exception.  Is there anything else I need to do
to convince matplotlib that it doesn't need my local display?

thanks!

Hi:

I am having problems with the \dagger LaTex symbol. The following code

import matplotlib.pyplot as plt

plt.plot([1,2,3])
plt.title(r'$ \dagger $')
plt.show()

produce a long Traceback that ends in

File "/usr/lib/pymodules/python2.6/matplotlib/mathtext.py", line 1997,
in raise_error
    raise ParseFatalException(msg + "\n" + s)
ParseFatalException: Expected end of math '$'
$ \dagger $ (at char 0), (line:1, col:1)

Other LaTex symbols works OK. For instance, if I use plt.title(r'$
\diamond $') instead, it works. I checked in mathtext.py, and \dagger
is in the list of symbols.

I am running Matplotlib '0.99.1.1'.

Any idea about this problem?

Alejandro.

Apologies -- I should have read the subject line!  :)

Hello Robert,

Thank you for your kind response, but I'm looking into py2app, for Mac OSX,
and it is a bit different than py2exe. I do have a py2exe script working
(lots of examples around), but I'm still a bit lost on the Mac-related
stuff.

cheers

Carlos

Hi Carlos,

It's a bit tricky giving you a complete example as the specifics will vary
considerably depending on which versions of python, matplotlib & wx you're
using:

I'd point you toward the wxPyWiki page at:
http://wiki.wxpython.org/py2exe-python26  which gives a pretty sound example
based on an output produced by GUI2Exe (written by Andrea Gavana)

As for matplotlib specifically, see:
http://www.py2exe.org/index.cgi/MatPlotLib (again depending very much on the
versions you're using), I've found that the first example given works
perfectly.

Hope that helps!

Hello all.

I've been looking for a good example of setup.py to build a bundle app with
wxpython+matplotlib.
Can someone share or point me in a direction?

thanks

Aha!  So that's where .config came from, also.  IPython is using it; I 
suppose we should, too.

This is coming from CXX.

I am not going to be able to figure out what the problem is, but those 
who are (the C++ wizards) will probably want to see the full stack 
trace, as well as the matplotlib version and the compilation parameters: 
platform, compiler, python version, etc. The first part of the output 
from setup.py build has all that.

It is a standard directory in linux now.  Started by the freedesktop.org, I
think.  Personally, I prefer it over having ~/lib, ~/bin and such cluttering
my home directory.
