matplotlib-users Mailing List for matplotlib (Page 6)

Thanks for the pointer to the new egg installer of Enthought.
Nice app, which I will use.
But this is, IMHO, not what we need to move the python/numpy/scipy/mpl combo
into the more mainstream use.
Many potential users won't know what to do with the long list of packages
that they have never heard of.
I think it would be very useful to have one installer that gets a reasonable
distrubtion installed (like the old Enthought installer).
Isn't something like that in the works for the Mac?
We can even make a python/numpy/scipy/mpl and then a seperate one that also
includes ipython and wxpython, for example.
Or maybe a webpage where you can just select what eggs to install.
Would that be doable?
Anybody else think this is what we need?

Ah..I see what was going on; the numerical ticks are output in LaTeX
math mode (e.g., 123ドル$) and therefore rendered in CM if the specified
fonts do not provide any math fonts. Is there a way to use LaTeX font
packages such as euler, ccfonts, and cmbright?

Apparently the weirdness I observed is a bit more subtle than I
described: changing the font with the usetex setting on does indeed
change the font used for the plot title and axis labels, but not for
the axis ticks. Changing the font with the usetex settings off causes
the selected font family to be used for the axis ticks.

AJ, complete accident to get offlist (apologies!)
I have python located in:
/usr/bin/python
but there is also a python located in
/opt/Plone-2.5.2/Python-2.4.4/bin
To be honest, I have no idea which one Zope/Plone uses... I had
assumed it was the latter, how can I check that?

Not clear, If I:
% python setup.py build
% python setup.py install
It's just going to install in the default /usr/ locations. Are you
saying that I need to run ./python setup.py build / install using the
'python' from the zope instance?

Hello,
I want to use matplotlib with Plone. I have it installed on my
machine, but not for the Plone instance of Python. What are the steps
I need to take to install it so that it is recognized by the Plone
Python instance?
Thanks!

Yes, this is the problem. matplotlib needs straight truetype fonts
(ttf) , not the more sophisticated opentype fonts and font suitcases
that come with macosX.
Most fonts in standard Apple places:
/Users/agn/Library/Fonts/
/Library/Fonts/
/System/Library/Fonts/
are .dfont or .otf etc... these don't work.
Except e.g. sans serif InaiMathi
 fantasy Chalkboard
which are straight .ttf, so do work.
If you have e.g. Gerben Wierda's latex installation gwtex, or probably
also the mactex distribution, this comes wilth various ttf versions of
the system fonts.
E.g I have the old gwtex based on tetex which comes with
gillsans [in light heavy etc..],hoefler ( a very nice serif
font),helveticaneue,lucidagrande,optima,verdana,didot and futura.
In my distribution these fonts are in
/usr/local/teTeX/share/texmf.gwtex/fonts/truetype/gtamacfont
if you want to use fonts like this, you either have to modify the
search path in font_manager.py to include the directories *directly*
containiong the .ttf files, or symlink the .ttf files into the
matplotlib directory holding vera.ttf etc...
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packag=
es/matplotlib/mpl-data/fonts/ttf
I believe you can make your own .ttf files from any standard Mac .otf
or .dfont using Fondu
[ http://fondu.sourceforge.net/] -- again included in Wierda's teX
installations.

There's actually a real MPL bug in there (not just the
NotImplementedError) but I'll report it separately in a minute.

Well, unfortunately it seems that inkscape is crashing python
itself... I made a trivial .eps in mpl with:
In [1]: plot(range(10))
Out[1]: [<matplotlib.lines.Line2D instance at 0x8f45a8c>]
In [2]: title(r'Some \LaTeX $\int_0^\infty f(\gamma) d\gamma = 1$')
Out[2]: <matplotlib.text.Text instance at 0x8f4590c>
In [3]: savefig('foo.eps')
and when I tried to load it into inkscape, I got this very nasty traceback:
*** glibc detected *** /usr/bin/python: free(): invalid pointer: 0x4081e4e0 ***
======= Backtrace: =========
/lib/tls/i686/cmov/libc.so.6[0x400ee7cd]
/lib/tls/i686/cmov/libc.so.6(cfree+0x90)[0x400f1e30]
/usr/lib/skencil/Sketch/../Lib/streamfilter.so[0x404e7ce5]
/usr/lib/skencil/Sketch/../Lib/streamfilter.so[0x404e7cd2]
/usr/bin/python[0x8110e6a]
/usr/bin/python(PyEval_EvalCodeEx+0x313)[0x80c9903]
etc.
At this point, this is really becoming OT for the mpl list, so I'll
stop. But if anyone has the time, it might be worth sending this
example to the inkscape list so they work on it and hopefully fix it.

The dvips route is not so simple. First matplotlib creates the
PostScript file with all text strings replaced by tags, and this is
fed to LaTeX using \includegraphics. The psfrag package replaces the
tags with LaTeX constructs, and then the dvi file is converted using
dvips into the final postscript file. There is no equivalent to psfrag
that works with pdf (at least none that I know of).
Probably you could create a pdf file without any texts and input that
in your LaTeX file, and then -- with sufficient LaTeX-fu -- render the
text strings at the correct positions, and run the LaTeX file through
pdflatex, because pdftex includes a pdf parser so that you can do
\includegraphics{foo.pdf}. So in that sense it may be generalizable,
but it won't be a direct port of the ps backend.

What's the problem of using dvi2pdf, dvipdfm, dvipdfmx, or soemthing =20
like that for PDF?
Looks quite similar to the dvips route for Postscript to me?

FWIW, I have the same problem: eps files produced on OS X are huge,
and somehow broken. My guess is that the fonts that come with OS X
have some advanced features, which should somehow be stripped out when
embedding into an eps file.
Perhaps one way to address the problem would be to use fonttools1 to
read the font file, prune the resulting data structure to include just
the characters needed, and again use fonttools to output the structure
into the eps file.

The usetex feature is implemented for the Agg backend (i.e., png
output) using dvipng, and for the PostScript backend using (I think)
dvips with psfrag, and neither of these is easily generalizable to
work with svg or pdf. However, some time ago I committed the
beginnings of a dvi parser and a little support code in the pdf
backend, enough to get a small demo almost working:
http://article.gmane.org/gmane.comp.python.matplotlib.devel/2687
I have no idea how difficult it would be to get this working in the
svg backend, but in the pdf backend the biggest hurdle is probably in
generalizing the current font support so that the TeX fonts can be
embedded.

I tried to export an .svg from MPL (0.90.0rev3131) with
rcParams['text.usetex']=True and got a NotImplementedError (same for the pdf backend
with usetex, see attached log). I was wondering: Is it (technically) possible to have

Anyway, to work with MPL-images (.ps/.eps) in Inkscape, I installed pstoedit but
loading these files doesn't work (seems not to recognize them as images).
Sorry if I'm driving the Inkscape-stuff a bit OT here, but:
What version of Inkscape & friends are you using? I'm using pstoedit 3.44, Inkscape

Hi,
I have an interesting problem using fonts in matplotlib on OS X 10.4. 
When I use a font other than the Bitstream Vera provided with MPL 
0.90.0, I cannot create readable eps files. More specifically, if I 
use a font from the OS X system choices, MPL happily creates an eps 
file, but it causes errors in preview, imagemagick, and ps2pdf. This 
occurs if I use either the PS or the TkAgg backend to create the eps 
file:
[joishi@ebisu test]$ ps2pdf test.eps
Error: /invalidfont in -dict-
Operand stack:
 Futura-Medium --dict:11/14(L)-- Font Futura-Medium --dict:

Current allocation mode is local
Last OS error: 2
Current file position is 618791
AFPL Ghostscript 8.51: Unrecoverable error, exit code 1
However, if the output is NOT eps, I can create and view pdf, png, 
and TkAgg plots with whatever font I choose. A code sample that 
produces the above error on eps output is below.
I hope someone might be able to shed some light on my problem. I have 
not been able to test the eps file on another platform; the bug may 
well rest on OS X outside of MPL. Unfortunately, I need eps files for 
a journal, and I would like to use a font other than Vera.
thanks,
jeff oishi

Yes, because dvipng - version works fine.

If you're fortunate enough to be using the wx backend, there is a
Copy_to_Clipboard() method which works great: In a wx App, Ctrl-C can
easily be bound to copy the figure to the clipboard, then paste it
into apps such as Word. I tend to find better results from saving a
higher-resolution PNG and inserting that into documents, but this
copy-and-paste works great for quick prints (whereas printing directly
from a wxApp seems to be very fragile and change with every wxPython
release)
I think pylab may not give you access to the Copy_to_Clipboard() method.

changing the font family works for me. Maybe you should try deleting 
your .matplotlib/tex.cache and trying again.

Is dvipng on your path?

Hi all,
I'm running matplotlib on Mac OS X and I've set text.usetex to True in
matplotlibrc, but if I try to run the tex_demo I get the error shown
below. If I'm right it's a problem with dvipng:
dvipng -version

Any idea?

Did you install pstoedit? If you do, you'll see that inkscape will
then be able to load .eps/.ps files in a fully editable format. I've
used it to fix decade-old plots for which the only thing around was
the eps file.

Glad it helped.
Cheers,

Sorry. Just discover that saving the file in emf format under Inkscape and then import into Word works even better. The eps engine in Word is really bad.
Hope that this info is helpful to others who are stuck in an Office world like me.

This is simply too good to be true. I played with manupulating MPL plots using Inkscape and man, somebody ought to include this in the MPL FAQ. I can move everything around by elements, touch-up or remove things I don't want, scale it, rotate it, you name it.
And then I can save the file in .eps and include into Office - and I don't loose any quality.
Perfect!
Here's what I learned:
a) Create the plot under MPL, saving the file in .svg format, and use the figsize argument to figure to create a plot of the proper size
b) Use Inkscape to open the .svg file and manupulate it. Save in .eps format.
c) Import the .eps file into Office.
d) Be happy and become famous and rich. (not)
Thanks again for all of the suggestions and tips.

Actually, Gimp is the problem. It's obvious they don't have a very good rendering engine. The plots looks very good under Inkscape.
