[Matplotlib-users] legend: axespad, pad, handlelen, labelsep - without effect
Hi,
please open the legend_demo3:
http://matplotlib.sourceforge.net/plot_directive/mpl_examples/pylab_examples/legend_demo3.py
1. add this line:
pylab.rc('legend', axespad=0.0, pad=0.0, handlelen=0.0, labelsep=0.0)
2. add this line:
pylab.rc('legend', axespad=10.0, pad=10.0, handlelen=10.0, labelsep=10.0)
Why all these parameters have no effect?

Re: [Matplotlib-users] mathtext acting weird under macosx backend
Can you please provide a screenshot of what you are seeing? I don't run Mac OS-X myself, so have no experience with the Mac OS-X-specific backend... however, it appears to be drawing regular text with native APIs (ATSUI etc.) and mathtext using matplotlib's freetype backend and blitting an image. If done correctly, there is no reason why one should be significantly lower quality than the other, but it is an obvious source of *difference*, particularly if font size is being handled differently in each case. I would suggest to Michiel de Hoon (author of Mac OS-X backend), to implement a full interface to mathtext for his backend (as PDF does, for instance) and do all glyph rendering with ATSUI, or the opposite -- do all glyph rendering by blitting freetype-rendered glyphs -- but not both. I have some concerns about the use of ATSUI, which, while arguably the better text system, will give different results than the Agg backends and cause cross-platform differences between plots, which is something in general we like to avoid. Cheers, Mike Zane Selvans wrote: First, *thank you* to whoever did the Mac OS X backend. It's much faster and smoother, and seems to behave much more reasonably all around. As in, show() actually does what it says it's supposed to do, and the figures don't have to be re-sized to draw themselves! However, there seems to be some kind of strangeness with using mathtext. When an axis label, tick label, title, or other text has any mathtext embedded within it, the font that the entire text object is rendered in changes, becoming larger, and often fuzzier (in an anti-aliased kind of way). On the plus (though confusing) side, the ticklabels that are being output by the basemap toolkit are now the same size as all my normal ticklabels, even though they appear to contain a mathtext character (the ^\circ for the degrees symbol), whereas previously, all the basemap ticklabels were coming out larger than the rest of my ticklabels, and I didn't seem to be able to alter them in the normal text object manipulation ways. I'm running on: Matplotlib SVN: v6677 Mac OS 10.5.6 macosx backend python 2.5.1 ipython 0.9.1 After I noticed this the first time, I quit out of the interpreter, and deleted the font cache from my .matplotlib directory, restarted, and the problem persisted. Any suggestions? I don't have any of the alternate tex rendering options set in my rcfile, just using plain mathtext. -- Zane Selvans Amateur Earthling z...@ideotrope.org mailto:z...@ideotrope.org 303/815-6866 http://zaneselvans.org PGP Key: 55E0815F -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Re: [Matplotlib-users] legend: axespad, pad, handlelen, labelsep - without effect
The legend class has been reimplemented recently and the name of some
keyword arguments (and their meaning) has been changed. Those
parameters you're using are deprecated ones. It is supposed to show
you some warnings if deprecated parameters are used, so what you see
is a bug. I'll take a look. I also noticed that the documentaion of
the pylab.legend is outdated. Take a look at
http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.legend
These are lists of deprecated parameteres
pad = None, # deprecated; use borderpad
labelsep = None, # deprecated; use labelspacing
handlelen = None, # deprecated; use handlelength
handletextsep = None, # deprecated; use handletextpad
axespad = None, # deprecated; use borderaxespad
So,
pylab.rc('legend', borderaxespad=0.0, borderpad=0.0,
handlelength=0.0, labelspacing=0.0)
should work.
Thanks,
-JJ

[Matplotlib-users] histogram(x, bin): x-axis range should be based on bin.min() and bin.max() when bin is a sequence
Hi, we got this Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=503148 Citing: the following python code creates a histogram with an x-axis range of 0.1 min to 0.3 max (based on the mins and maxes of the x rather than bin). the bins should be used to size the axis since the user specified that he wanted to see those specific bins (even though they are empty). note that the 'range=' option would be a potential solution, but it is ignored when bin is a sequence (presumably because the range would be chosen based on bin's limits, but this isn't so). from pylab import * x = [0.18,0.22,0.19] bin = [0,0.1,0.2,0.3,0.4,0.5] hist(x,bin) show() i believe that the x-axis ranges should instead be based on the mins and maxes of bin when it is a sequence. please forward this report upstream or let me know if you believe that it belongs there. thank you for your consideration I tested that this applies to 0.98.3. Is this a bug? Thanks, Ondrej -- ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

Re: [Matplotlib-users] legend: axespad, pad, handlelen, labelsep - without effect
John, I updated api_chages.rst (but you'd better check my english). I also made a few changes so that a warning is issued when deprecated parameters are used in rc file. I deleted deprecated parameters in lib/matplotlib/rcsetup.py and also from lib/matplotlib/mpl-data/matplotlib.conf.template. I did my own test and it worked well for me, and I hope it does not cause any problem.
