matplotlib 0.91.3 is released = This is the maintenance bug-fix and feature enhancement release of the 0.91 branch. Because the 0.98 refactoring introduced more code breakage than usual, we decided to branch the 0.91 series for users unable to upgrade right away. We have ported as many bug fixes and features to the maintenance branch as possible, and these are now available for release as 0.91.3. Homepage: http://matplotlib.sf.net Downloads are available at http://sourceforge.net/project/platformdownload.php?group_id=80706 with binary installers for windows and OS X.

[Matplotlib-users] ANN: matplotitb-0.98.0 milestone release
matplotlib 0.98.0 is released = This is a milestone release of matplotlib with a significant internal refactoring to support better transformations, path drawing, and readily extensible coordinate projections and scales. Michael Droettboom of STScI did the lion's share of the work, but a large number of developers have made many significant contributions. This is such a significant improvement of the matplotlib code base that we are jumping from the 0.91 series to the 0.98 series, in anticipation of rapid progress to 1.0. Downloads are available at http://sourceforge.net/project/platformdownload.php?group_id=80706 with binary installers for windows and OS X. Thanks to Charlie Moad for the builds and release. See the migration document at http://matplotlib.sf.net/MIGRATION.txt, the API changes at http://matplotlib.sf.net/API_CHANGES, and the full CHANGELOG at http://matplotlib.sf.net/CHANGELOG . You should manually any old install of site-packages/matplotlib since the new version will not properly install over it. We've also done some work on the look and feel of the web site, with a new logo an a less jarring color scheme, and are in the midst of a fairly significant documentation effort, so if you have any interest in writing documentation or doing website design, join us on the developers list and ash how you can contribute. What's new in matplotlib 0.98 = This is also available on the website at http://matplotlib.sourceforge.net/whats_new.html better transformations -- In what has been described as open-heart surgery on matplotlib, Michael Droettboom, supported by STScI, has rewritten the transformation infrastructure from the ground up, which not only makes the code more intuitive, it supports custom user projections and scales. See http://matplotlib.sf.net/doc/devel/add_new_projection.rst and the http://matplotlib.sf.net/matplotlib.transforms.html module documentation proper paths For the first time, matplotlib supports spine paths across backends, so you can pretty much draw anything.

[Matplotlib-users] Qt4 backend in Matplotlib 0.98
Sorry for repeating myself... but congratulations again for the new Matplotlib release, especially for the Qt4 backend improvements. A few days ago, I was about to suggest some improvements in Qt4 backend, but what you've done is so much better. The Matplotlib toolbar is now a real Qt toolbar, and it changes everything: appareance, integration in a complex GUI. That is a great step ahead for matplotlib widgets in Qt GUIs. Another good reason to choose Qt4 as default backend in Matplotlib. Thanks for your great work. Regards, Pierre Raybaut - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Matplotlib-users] Controlling math mode font weights
First to correct some confusion (and a good candidate to add to the new
docs that everyone is working so hard on...): mathtext and usetex are
completely independent systems, and you can only use either one of the
other. Therefore, if usetex is True, none of the mathtext settings will
have any effect.
Erik Tollerud wrote:
I am having trouble figuring out how to control the weight of labels
and text with the usetex option set to True. I would like to force
all mathmode labels and text to be at least bold. I can imagine doing
this either by substituting a font (i.e. changing the mathtext.fontset
to 'custom' and all of the different matext.?? to some boldface font),
or some the font.weight rc parameter, but neither of these has any
effect - whatever I do, the mathmode and other TeX formatted text
stays the same weight. How can I make it just turn up the weights to
bold without changing anything else?
This is not something that is directly supported. When usetex is True,
all of the rendering happens with (La)TeX, so you're limited by what
(La)TeX can do. You would probably need to find some LaTeX package that
does this, and then \include it in the LaTeX preamble using the
text.latex.preamble setting. My quick Googling didn't reveal anything
that can do that, however.
You can get bold in a math expression by enclosing content in \mathbf{},
but that is by definition upright bold. The reason, I believe, is
that (core) LaTeX simply doesn't include the fonts for Greek characters
and other symbols in bold.
Cheers,
Mike

[Matplotlib-users] add an arrow to a lineEnd
Hello, the original problem that I have is to add an arrow to the end of a plotted line. I tried this from pylab import * x=linspace(0, 1.85, 100) y=sin(x) dx=x[-1] - x[-2] dy=y[-1] - y[-2] plot(x,y,lw=2) arrow(x[-2], y[-2], dx, dy, width=.02, length_includes_head=True, head_length=sqrt(dx**2+dy**2), lw=0, overhang=.1) But this is ugly. And when I zoom in the arrowsize isnt scaled with the linewidth. Any idea instead to switch to the pyx package? By, Friedrich - This SF.net email is sponsored by: Microsoft Defy all challenges.

That is the facecolor of the figure patch, and you can set it like:
fig = figure(facecolor='red', edgecolor='white')
and also when you save you can set it there, since we have different
defaults for display and hardcopy
fig.savfig('myfig', facecolor='white', edgecolor='white')
both of these defaults can be changed in the matplotlib configuration

following settings:
figure.figsize : 8, 6# figure size in inches
figure.dpi : 80 # figure dots per inch
figure.facecolor : 0.75# figure facecolor; 0.75 is scalar gray
figure.edgecolor : white # figure edgecolor
savefig.dpi : 100 # figure dots per inch

This is weird: it is working on my end once I update my backend
setting to TkAgg. After running the 0.98 installer do you have
pylab.py in site-packages? Make sure you remove all matplotlib traces
from site-packages before installing.

[Matplotlib-users] Make tick labels thicker
Hi, First of all, thanks to the developers for such a great Python plotting package. I use matplotlib more and more for my work. There is one thing, which I cannot get to work, namely to change the linewidth of the tick lines. I have tried ticklines = ax.get_xticklines() ticklines.extend(ax.get_yticklines()) for line in ticklines: line.set_linewidth(10) but nothing changes. I can change the color and other properties, but no matter what I set for the linewidth, it does not change. I have also tried to go in and ticklines[0]._linewidth = 10 but again no change. If I do a similar thing for the color ticklines[0]._color = 'b' the color is changed. I use matplotlib 0.91 on a RedHat EL 4 machine. Any ideas on how to solve this would be much appreciated. I have searched the mailing lists and the site, but could not find a solution (apologies if I should have missed it) Best regards, Berit Berit Hinnemann Research Scientist | Characterization Department | Research Development Haldor Topsøe A/S Nymøllevej 55 DK-2800 Kgs.

This is weird: it is working on my end once I update my backend setting to TkAgg. i tried TkAgg as well but still no go. After running the 0.98 installer do you have pylab.py in site-packages? yep, its right there. very weird. does matplotlib fiddle with sys.path or some such? Make sure you remove all matplotlib traces from site-packages before installing. i did that and re-installed, same problem. Les - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Matplotlib-users] easy_install and eggs
If you rename matplotlib-0.98.0-py2.5-macosx-10.3-fat.egg to
matplotlib-0.98.0-py2.5.egg,
easy_install will install it from the disk.
I'm not sure why this happens. I've noticed lots of Mac OS X eggs with
cruft at the end of the
filename, which prevents their installation through easy_install.
Renaming is all it takes
to install them; still, it's annoying.

Re: [Matplotlib-users] Update to Matplotlib and Numpy producing error
Unfortunately, I think someone else was on the maillist with a similar problem, and perhaps our two mails got confused. I have always been using 0.99 as far as I know. It got nuked when I deleted the old matplotlib. I wonder why it couldn't find geos the second time around? Once again, though, I'll let you know how things go. It's a good idea to pull the toolkit out of the matplotlib directory to avoid this very problem. I'll give that a try, by direct copying and changing my code. Probably a lot of example code might need changing as well.
