Re: [matplotlib-devel] example data in example code
So, I just downloaded 0.99 rc1 and wanted to play with axesgrid examples and
got the results you reported below in your example. I am in fact naive, and
its not clear to me how to get around this problem of the demo_image module
not being found. What is the solution?
Thanks,
Josh

Re: [matplotlib-devel] binary installers for python2.6; libpng segfault, MSVCR90.DLL and mingw
I am new to trying to build matplotlib from svn and believe I am up against the issue described in this thread. That is, building matplotlib on Python 2.6.2/Windows, compiling/linking with MinGW seem to go fine but upon trying to from pylab import * I get (lots of traceback that culminates below) C:\Python262\lib\site-packages\matplotlib\image.py in () 19 # For clarity, names from _image are given explicitly in this module: 20 import matplotlib._image as _image ---> 21 import matplotlib._png as _png 22 23 # For user convenience, the names from _image are also imported into ImportError: DLL load failed: The specified procedure could not be found. ) even though matplotlib\_png.pyd exists. I am wondering if there has been any progress on this front? I found http://www.nabble.com/Python-2.6.2-installation--td23996471.html this thread which suggests using Visual Studio 2008 (VS9) instead of MinGW, but that was for 0.98.5.3. I installed VS9 and followed the instructions in that thread but now when I try to import pylab Visual Studio's Just-In-Time Debugger pops up telling me I have an unhandled win32 exception in python.exe Can anyone comment on a verified way of building the latest matplotlib on Windows/Python 2.6.2? I keep going down dead ends and would like to figure out if its me or if I have just been down now-known bad paths.

[matplotlib-devel] Another Gallery example?
I have another Gallery example that I'd like to post if anyone finds it worthy. It is just a polished version of the scatter_hist example at http://matplotlib.sourceforge.net/examples/pylab_examples/scatter_hist.html See the most recent graphic on this thread: http://old.nabble.com/How-to-overlay-an-image-on-a-multi-plot--td28111498.html I have contributed a few gallery examples in the past http://matplotlib.sourceforge.net/examples/api/radar_chart.html http://matplotlib.sourceforge.net/examples/pylab_examples/barchart_demo2.html http://matplotlib.sourceforge.net/examples/pylab_examples/boxplot_demo2.html and I am just trying to (slowly) help with getting publication quality graphics into the gallery, a la R's gallery at http://addictedtor.free.fr/graphiques/thumbs.php (matplotlib looks s much better). By "publication quality" I just mean graphics that have legends, axes labels, specified axes ranges etc, so that in one example people see a lot of the functionality they'll likely use a lot. If anyone is interested, I can take my code and generalize it with fake data and axes labels, add some comments, etc. Cheers, Josh - Josh Hemann Statistical Advisor http://www.vni.com/ Visual Numerics jhemann at vni dizzot com -- View this message in context: http://old.nabble.com/Another-Gallery-example--tp28145163p28145163.html Sent from the matplotlib - devel mailing list archive at Nabble.com. -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

Re: [matplotlib-devel] improved source code for radar chart example in matplotlib docs
Hi Dan, Is http://matplotlib.sourceforge.net/examples/api/radar_chart.html?highlight=radar this the example you are referring to? If so, this is the one I submitted to the gallery a couple of years ago and I would be happy to see the underlying methodology improved.
