Re: [Matplotlib-users] More funky font baselines
Thanks. I think I have this fixed in SVN again...
Basically what's happening is that Freetype's hinting imposes a vertical
scale on the glyph that wasn't being taken into account.

[Matplotlib-users] Mathtext font size difference
Mike,
Is there supposed to be a difference in the size of text printed with and
without mathtext? Here's a simple script that shows what I'm talking about:
import matplotlib.pyplot as plt
f = plt.figure()
ax1 = f.add_subplot(1,2,1)
ax1.set_title('Hello')
ax2 = f.add_subplot(1,2,2)
ax2.set_title('$Hello$')
plt.show()
And here's my matplotlibrc:
backend : GtkAgg
mathtext.fontset : stixsans
font.size : 10.0
savefig.dpi : 100 # figure dots per inch
mathtext.default : regular
I've attached a copy of what that looks like on my system.
Sorry I keep finding these things. :)

Re: [Matplotlib-users] Mathtext font size difference
They're actually different fonts. The one on the left is Vera Sans, the
one on right is Stix Sans. There is a bug where regular (meaning Vera)
text in math was getting mapping to Stix Sans when mathtext.fontset is
set to stixsans. (This should now be fixed in SVN).
All that said, fixing this bug will mean it's now fairly easy to get
an unintended mix of Vera Sans and Stix Sans in math expressions. For
example, $A \bf{A}$ will draw the first A in Vera and the second in
STIX. There's no easy way around that, since we don't currently support
rich text for non-math fonts. To avoid this mix of fonts within the $
$, you would probably want to set mathtext.default to rm.

Re: [Matplotlib-users] How to turn off all clipping?
Hatch, Sara J wrote: Matplotlib Folks, How do I turn off all clipping when making a plot? It seems like everything has a set_clip_on argument, but I couldn’t figure out how to set all of these to False without explicitly doing so in every plot call. I would assume that there is a way to do this using an rcParam or the matplotlibrc file? No there isn't, and I think this is the first time this question has come up. Usually some clipping is desired. I doubt the need for absolutely no clipping is common enough to justify an rcParam entry. If you think there is a common use case that should be supported, though, please elaborate. Every artist has a set_clip_on() method, so to turn off all clipping you are stuck having to find all the artists and turn off clipping on each individually. Maybe something like this (untested): def noclip(ax): Turn off all clipping in axes ax; call immediately before drawing ax.set_clip_on(False) artists = [] artists.extend(ax.collections) artists.extend(ax.patches) artists.extend(ax.lines) artists.extend(ax.texts) artists.extend(ax.artists) for a in artists: a.set_clip_on(False) I suspect this will not necessarily take care of everything; there may be compound artists that do not define their own set_clip_on method to propagate down to the sub-artists.

Re: [Matplotlib-users] Installing matplotlib for python 2.6 under windows
Aha, I did not have VC++ 2008 EE on my PC, so it actually didn't compile anything. Now that I have it, I get a dependency problem with Freetype2. The build command fails with: c:\python26\matpotlib\src\ft2font.h(13) : fatal error C1083: Cannot open include file: 'ft2build.h': No such file or directory I downloaded the windows binaries of freetype2 in gnuwin32 project, but it doesn't seem to help. Or do I need to download freetype2 source and compile that. If so, maybe there is a detailed (step-by-step) guide installing the dependecies (libpng, zlib, freetype), because they don't seem to have windows installers like numpy has that actually works with matplotlib.

[Matplotlib-users] optimal dpi for imshow
Is there a way to figure out the optimal dpi for imshow when saving as a png
so that all the pixels are visible?
I do something like the following:
import matplotlib.pyplot as plt
plt.clf()
image = np.random.normal(0,1, (1000,1000))
plt.imshow(I, cmap=plt.cm.gray, interpolation='nearest', aspect='equal')
plt.axis('off')
plt.title('title')
plt.savefig('~/tmp/test.png, dpi=600)
If the size of 'image' is too large or dpi is too small, the elements in the
matrix get blended. I would like to set the dpi to the minimal necessary so
that the elements are distinct.
Any tips appreciated.
