Re: [matplotlib-devel] Bug in Interactive Save with WX Backend
No problem. Many of the developers don't follow the tracker as closely as the mailing list. I'll look at this bug later today. Cheers, Mike Robert Schroll wrote: Dear all, I hope this isn't considered gauche, but: A few weeks ago, I added a bug [1] I had found when saving figures from the toolbar with a WX-based backend. I think it's a simple issue, and I included the simple fix that worked for me. Since then there's been no apparent activity on it. Is there something more I need to do on it? If someone is already taking care of it, I apologize for hassling you. But if the fix is as simple as I think it is, it would be a shame to have it fall through the cracks.

Re: [matplotlib-devel] Incorrect output from demo_text_path.py on mac
On Tue, Nov 3, 2009 at 4:23 AM, tcb thecolourblu...@gmail.com wrote: and if I convert the dvi with dvipng, it all seems in order (demo_text_path_tex.png). I haven't looked closely into how the textpath stuff works, but I thought it would read the dvi as a path, and display that on the screen- if that is correct then I dont know how it ends up displaying a different symbol from what is in the dvi file. Well, dvi files only contains the name of the tex font. What textpath does is to pick up corresponding type I font and convert them to path using the freetype library (as far as I know, this is what dvipng and matplotlib pdf backend does). So, my guess is that, textpath is somehow picking up wrong fonts, or wrong glyphs. The code works fine at least in my mac os X tiger w/ texlive 2008, and in ubuntu with texlive 2007. As I don't have any access to mac os X 10.6, it would be hard to track down what is wrong. Here are a few more test I wish you to run. *) Check if pdf backend produces a correct result. Do not use textpath example, but simply use text command with usetex=True, and see if the pdf output is okay. FWIW, the textpath code is largely borrowed from the pdfbackend. *) Run the attached code, and post the terminal output. The output is basically the name of the tex font and the name of the substituted type1 font, etc. For your reference, here is my output. texname, type1name, enc, char_id cmex10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmex10.pfb None CMEX10-34 cmsy10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmsy10.pfb None CMSY10-49 cmex10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmsy10.pfb None CMEX10-88 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmmi12.pfb None CMMI12-110 cmr17 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMR17-61 cmr17 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMR17-49 cmsy10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMSY10-0 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-101 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-105 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-25 cmr17 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMR17-50 cmmi12 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMMI12-110 cmex10 /usr/local/texlive/2008/texmf-dist/fonts/type1/bluesky/cm/cmr17.pfb None CMEX10-35 pncr8r /usr/local/texlive/2008/texmf-dist/fonts/type1/urw/ncntrsbk/uncr8a.pfb /usr/local/texlive/2008/texmf-dist/fonts/enc/dvips/base/8r.enc Century%20Schoolbook%20L%20Roman-232 Regards, -JJ demo_text_path2.py Description: Binary data -- Come build with us!

Re: [matplotlib-devel] Layout of subplots in output
Hi JJ 2009/11/2 Jae-Joon Lee lee.j.j...@gmail.com: I now think this is not the dpi issue. Can you check the size of your figure in mac os X backend, after the plot is drawn? print f.get_size_inches() 8x6 inch is the default. It says [4, 2.52], so I think you are right! So, my recommendation is to use smaller dpi for screen display (default is something like 80), and increase the dpi when saving the figure (savefig has a dpi parameter). This fixes the problem. Now, why does the MacOSX end do this when none of the others do? Thanks for helping me track this down! Stéfan -- Come build with us!

[matplotlib-devel] curved quiver arrows
How hard would it be to extend the quiver command to support curved arrows? For example, the U and V arrays, instead of giving just the vector, could for each vector give a list of x coordinates and a list of y coordinates for each segment of a vector. Additionally, C could give either a color for the curved vector, or a list of colors for each segment of the vector. Thanks, Jason -- Come build with us!

[matplotlib-devel] [ANN] For SF Bay Area residents: a discussion with Guido at the Berkeley Py4Science seminar
Hi folks, if you reside in the San Francisco Bay Area, you may be interested in a meeting we'll be having tomorrow November 4 (2-4 pm), as part of our regular py4science meeting series. Guido van Rossum, the creator of the Python language, will visit for a session where we will first do a very rapid overview of a number of scientific projects that use Python (in a lightning talk format) and then we will have an open discussion with Guido with hopefully interesting questions going in both directions. The meeting is open to all, bring your questions!
