OK, I think we are ready to roll. Charlie, you can tag the release
and get to work on the binaries and release when you have time. I'll
be in sporadic email contact until Monday, so why don't you do the
announce (feel free to just past in the updates in the CHANGELOG). I
haven't been testing 0.91.x like I have 0.98.x so let's just release
the 0.98.3 point release at this time. I don't think there are any
mission critical bugs in 91.x that require a release right now.

Sandro, if you want to test the final/final, it is at
http://matplotlib.sourceforge.net/tmp/matplotlib-0.98.3.tar.gz (svn
r5941)

So should I be including the built docs in the release now? I have a few warnings that make it through to the pages. I am building them on Ubuntu.

Scratch that. It looks pretty good with the latest svn. Now the question as to where to put the built docs? "doc/build/html" seems a bit hidden. Has this been discussed yet?

more demos of mpl with wxPython


For those who may be interested: 
I plan to use mpl for some serious plotting in my programs featuring
wxPython GUIs. To get started, I've written a couple of non-trivial demos
with mpl and wxPython and posted them online (code and all). 
http://eli.thegreenplace.net/2008/08/01/matplotlib-with-wxpython-guis/

It is my hope that others will find this code useful. And if you have any
corrections, insights or general comments, please let me know.

Eli

Re: Thin wedges missing from pie graph

Hmmm...  The puzzling thing is that 0.91.2 works for me with the example 
you provided.  Can you try clearing out the installation directory 
(usually /usr/lib/python2.5/site-packages/matplotlib/) and trying again?

Cheers,
Mike

Moving legend with mouse?

I'm using matplotlib 0.98 together with wxpython 2.8.8.0. It would be nice to be able to click on the legend and move it with the mouse. Is that possible? Is there a simple way to do this? Has anyone tried this or can someone point in the direction?

Thanks,
Soren

Re: Thin wedges missing from pie graph

I deleted the matplotlib directory (there was one at the path you provided) and reinstalled 0.91.2; the behavior was identical.

The 0.98.3 release will be out very soon -- just keep your eyes out

Crash on import with CGI wrapped by PHP--unhappy with .matplotlib directory?

I have a PHP script which authenticates a user and I am trying to get the PHP script to wrap a Python script using matplotlib.

As it is, the script mostly works when invoked from the command line or as its own CGI script. When I call it from a PHP script, it doesn't produce output, and testing found that when I call a Python script from a PHP script, output works before but not after "import matplotlib": if the PHP script calls a script of:

#!/usr/bin/python
print "Before import matplotlib."
import matplotlib;
print "After import matplotlib."

the first print statement succeeds but the second one fails; the server log shows a crash of:

Before import matplotlib.Traceback (most recent call last):
File "/home/jhayward/bintmp/test.py", line 5, in <module>
    import matplotlib;
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line 639, in <module>
    rcParams = rc_params()
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line 562, in rc_params
    fname = matplotlib_fname()
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line 513, in matplotlib_fname
    fname = os.path.join(get_configdir(), 'matplotlibrc')
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line 207, in wrapper
    ret = func(*args, **kwargs)
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line 403, in _get_configdir
    raise RuntimeError("Failed to create %s/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data"%h)
RuntimeError: Failed to create /root/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data

I think this error is somewhat misleading; it persisted after I ran a "chmod -R 1777 /root/.matplotlib".

What is the proper way to adjust things so matplotlib will be happy with its .matplotlib directory?

Re: Crash on import with CGI wrapped by PHP--unhappy with .matplotlib directory?

Just throwing out a suggestion here: You could try putting a 
matplotlibrc file in the same directory as your Python script -- it will 
use that instead of the one in ~/.matplotlib.

Cheers,
Mike

PS Even though these are just short demos,

On my website it says that all code is LGPL, unless stated otherwise. But
you're probably right and it makes sense to add a license to each file. So I
added it in the comment at the top.

Interesting. I wouldn't imagine anyone would hesitate borrowing code from a
demo because of a lack of license.
