Re: [Matplotlib-users] missing lines on graph with upgrade to 0.98.0
It seems like it does not connect the last point to the first point. This
also happens with the matplotlib.patches Polygon.

Is there a way to get the underlying array that the fill function uses to graph a polygon? This is assuming that it uses an array.

Re: [Matplotlib-users] fill function
I just read your question more closely -- that you want to multiply an array by an array that describes the polygon. Do you mean the array of vertices that describe the polygon or something like a 2D rasterization (image) of the polygon? I perhaps wrongfully assumed you just wanted to do hit-testing on a polygon. What I was thinking (and this still may be relevant to your problem) was: from matplotlib.path import Path # Create a unit square path = Path([[0, 0], [1, 0], [1, 1], [0, 1], [0, 0]]) # Test for some points that are inside and outside of the square assert path.contains_point([0.5, 0.5]) assert not path.contains_point([1.5, 0.5]) If you want to get an image of the polygon, it's probably theoretically doable, but won't be straightforward. It will involve working directly with the Agg backend, I think. Let me know your use case is, and we can step through that. Perhaps there's another way to achieve the same end result that won't require as much wrestling. Cheers, Mike Bryan Fodness wrote: Could you help me set this up? I am still fairly new to python.

Re: [Matplotlib-users] missing lines on graph with upgrade to 0.98.0
Bryan,
Thanks for pointing this out. Mike D. has made a change in the svn
trunk to restore the automatic closing of polygons made with the
patches.Polygon constructor, which is used by the fill command.

[Matplotlib-users] Build matplotlib 0.98 on OSX
Is this really the current solution to building matplotlib on OSX, installing a new compiler and hacking the python Makefile? I was able to build matplotlib 0.91.2 just fine on OSX, sometime around March I checked out the truck to fix a bug and discovered I couldn't build the svn version. Matplotlib is the only package with a dependency on gcc 4.2, all the other packages I build, numpy, scipy, ipython, etc... build with gcc 4.0. Why do you have this dependency? Is there an easier solution? I'm reluctant to upgrade to gcc 4.2 and loose the ability to build other packages I need. Chris On Thu, May 29, 2008 at 4:51 AM, Joshua Lippai [EMAIL PROTECTED] wrote: I've consistently been able to build matplotlib on OS X. Just make sure you have all the dependencies installed. Personally, I have lbpng and whatnot installed in /usr/local instead of /usr/X11. I don't know if that'll help. Also, I use the GCC 4.2 that Apple has available for download on developer.apple.com. Then you just change the Makefile in the /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/config/ directory to not use Wno-long-double or no-cpp-precomp. I also took out all the ppc arch flags since it was causing some issues there with my versions of libpng and whatnot technically not being universal binaries. If you don't want to build univeral binary versions of your dependencies or use the ones alread provided in /usr/X11 (which are universal I think), you should make Python only build for your architecture, which is what I did. My only issue with matplotlib thusfar seems to be the inability to do the plot3d examples from the scipy website, but I'm told that stuff is officially unsupported anyway.

Re: [Matplotlib-users] easy_install and eggs
The problem appears to be the -fat at the end of the file name. The filename 'matplotlib-0.98.0-py2.5-macosx-10.3-fat.egg' _works_, but then downloads the tarball and tries to build the source, which _fails_ with gcc 4.0.
