matplotlib-users Mailing List for matplotlib (Page 5)

I'm using SVN matplotlib and wxPython 2.8.7.1, and I'm not running
into the problem. Though I may be interpreting your problem
incorrectly. I've attached a screen capture of the window that opens
up when I run your program.

I've had an ongoing problem building eggs of matplotlib that are statically 
linked to freetype. I thought I had it nailed, but evidently I do not. Here 
is my script:
export CFLAGS="-arch i386 -I/Developer/src/libpng 
-I/Developer/src/freetype/include"
export LDFLAGS="-arch i386 -L/Developer/src/libpng 
-L/Developer/src/freetype"
rm -rf build
python setupegg.py bdist_egg
The build of freetype in /Developer/src/freetype does not even have 
dynamic libs built. The basedir dict in setupext.py contains the following 
entry 
for OSX:
'darwin' : []
However, when the resulting egg is installed by users, they still get the 
following error:
ImportError: dlopen(/Library/Python/2.5/site-packages/matplotlib-
0.98pre-py2.5-macosx-10.5-i386.egg/matplotlib/ft2font.so, 2): 
Library not loaded: /usr/local/lib/libfreetype.6.dylib Referenced from: 
/Library/Python/2.5/site-packages/matplotlib-0.98pre-py2.5-macosx-10.5-
i386.egg/matplotlib/ft2font.so Reason: image not found
I thought I had my bases covered -- if anyone has some insight here, please
let me know. maptlotlib is the only missing piece of the "superpack" of 
modules that I distribute for OSX.

In the quest to discover the problem, I found that the problem exists 
in svn (version .98pre) but not in .91.2. Both with version wx-2.8.7.1.

I am posting here the minimal program that reproduces the problem, 
based on a modified embedded_in_wx.py. The axis shows up, and has 
the right limits, but no plot forms in the axis. Weird!

It looks like the text line is a problem. Latex doesnt like use of align or 
eqnarray environments inside figures. It looks like a latex limitation, not 
matplotlib. On the other hand, if you can figure out how to make it work in 
latex, and can prove that it is a limitation in matplotlib, please let me 
know so we can fix it.

Hello,
I just upgraded a number of things on my Mac OS X (Tiger) machine, 
including to the latest version of wx and matplotlib. I found that 
there is a bug in the display of dynamic plots with subplots. If I 
change the subplot line in the examples/dynamic_demo_wx.py to:
 a = self.fig.add_subplot(221)
instead of
 a = self.fig.add_subplot(111)
the plot never shows. It works for 111, and for 121, but not 221. 
Not sure why! It works in interactive mode, in ipython, but not in 
dynamic plot.
Any ideas?
		thanks,
			Brian Blais

I'm experimenting with installing a full python/numpy/scipy/matplotlib 
etc. suite on a RedHat Enterprise 5 system, and trying to document 
what would be the simplest procedure to accomplish each step.
I managed to install numpy using easy_install, but when I tried to 
install matplotlib using the same tool, I get the following errors:
error: Setup script exited with error: Command "gcc -pthread -fno- 
strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -

Any tips? Do I need to install some sort of back-end infrastructure 
first?
I'll be happy to provide more detailed error messages, or do some 
basic tests.
Thanks,

Hello,
I'm using today's svn source and I'm surprised that the following loop
does not get redrawn 10 times.
 for it in range( 10 ):
 plot( arange( it ) )
 draw()
 raw_input();
That is, within a 'ipython -pylab' session. Is this really a question
for the ipython folks? Or am I missing something here?
Thank you,
Glen Mabey

I put in a temporary workaround, but what we need is a numpy version 
check when mpl is imported. I can put something in based on parsing 
numpy.__version__; is there a better or more standard way to do this?

This bug seems to be Cairo-backend specific. The Python PDF backend 
seems to work fine. Most likely a problem in the Cairo backend and not 
Cairo itself, but I haven't dug any further.
Cheers,

Hey Manuel -- very cool example. I added this example to the svn
trunk (rewritten slightly to conform to recommended import style) as
examples/scatter_piecharts.py
Cool stuff,

I just tested it on OS X using the wxAgg backend, and it appears to be
fine. I've atached the pdf image. What GUI are you having matplotlib

You cannot call "draw_artist" until after the initial draw. So you
will either need to explicitly call fig.canvas.draw() first or put
your draw_artist command in a GUI handler that is not called until
after the initial draw event.

matplotlib svn requires numpy svn. Try upgrading your numpy and I
think this bug will go away.
JDH

My svn build of numpy does have numpy.ma.masked_invalid. Try building
numpy from svn instead of using 1.0.4. It's quite stable and has lots
of new features, plus it even passes all the numpy.tests.

Antonio,
Thanks for the report. It should be fixed now. Numpy svn has 
masked_invalid, so my earlier change worked for me, and I forgot that 
ma.masked_invalid is a new addition (and a nice one).

But all sorts of other issues would arise. The tricky bit to all of this 
is getting/building Universal versions of the various dependencies. I 
still have no idea why Apple doesn't just provide a few more common 
libs, like libpng and libfreetype (which is now included with X11, but 
as I understand it, that's an optional install). Anyway as we don't have 
any control over what Apples does (and even less control over what they 
have already not done!), we need other solutions:
My proposal:
We try to build a consensus among the MacPython community about a 
"standard" way to deal with common dependencies. There is now 
more-or-less a consensus that we should provide binaries for MacPython 
(and now 10.5's Apple python) that are statically linked against 
universal versions of all the dependencies. That works great, but the 
truth is that it's a pain in the $$%#@ to get those dependencies built 
right, so we've substantially raised the barrier for folks to build 
binary packages. Also, it seems a bit silly to separately deal with 
something like libpng for multiple packages. I think I've got at least 
four python extensions with libpng.
For example: Fredrik Lundh recently asked on the PIL list for 
recommendations as to what binaries he should provide for OS-X, and for 
someone to build them (he doesn't have a Mac). I set out to do it for 
him, and am still mired in dependency heck. Note that the key 
dependencies are the same as for Matplotlib (libpng, libfreetype)
My proposal for the "standard" way to provide the libs:
Kyng Chaos (William Kyngesburye)'s Frameworks:
http://www.kyngchaos.com/wiki/software:frameworks
He's got UnixImageIO, which provides libpng and others, and freetype, 
plus a bunch of others. They are all build as proper versioned OS-X 
frameworks, as well as a nice little hack where he puts soft links in to 
create a standard "unixy" hierarchy, so that they can be used by libs 
that don't understand frameworks.
Yes, it's a bit extra to tell folks to first install these two 
frameworks, then whatever the python package lib is, but I think it 
really would make it easier all around, particularly for package 
builders, and making things easier for package builders means that more 
binaries would be built properly, which would make things easier for users.
Note: William's Frameworks are all versioned properly, so there would be 
no harm in installing them multiple times, or having multiple versions 
installed. In fact, I think you could build a *.mpkg that had both your 
python package and the frameworks it needs, so that users would have a 
one download and one click install. It wouldn't hurt to have multiple 
packages with the same Frameworks installed this way.
Thoughts?

I'm using matplotlib 0.9.12 from ubuntu hardy 8.04.
To take advantage of the LaTeX handling capability in matplotlib,
I've added next two lines in /etc/matplotlib
text.usetex : True
text.latex.preamble : \usepackage{amsmath}
Then, I tried next test code.
from pylab import *
x = []; y = []
figure(figsize=(2,2))
plot(x,y,label=r'$\theta=0ドル.0deg'); axis([0,1,0,1]); legend()
text(0.5, 0.5, r'\begin{align*}x&=\alpha\\y&=\beta\end{align*}')
savefig('test.eps')
However, I've got the following error message without a resulting eps file.

I just found a PC with Debian etch and matplotlib 0.90.1 and the following 
error arises for me (no program exit):
 TypeError: Could not convert object to file pointer

I'm not an expert, but the pylab.__doc__ states
 This is a procedural interface to the matplotlib object-oriented
 plotting library.

I don't know. On my debian etch with matplotlib 0.90.0 also an error is 
raised, but different to the one of mpl 0.91.2
(AttributeError: 'NoneType' object has no attribute 'rfind').
Maybe in between there was a time where this problem occured.
Is it possible for you to update to 0.91.2?
regards and good luck!
Matthias

So I have:
In [2]: import matplotlib; print matplotlib.__version__
0.90.1
Why does pylab not have __version__?
So I guess it was fixed between 0.90.1 and 0.91.2
Thanks,
John.

John, thanks for asking, Matthias for answering, this question, which I've 
always been afraid to ask... :)

It doesn't appear to exist in VS2008 -- at least I can't find it in the 
online docs. Maybe someone else can enlighten me.
In the meantime, I just wrote my own round function and switched to use 
that. Please update from SVN and let me know how it goes. And again, 
thank you for your patience.
Cheers,
Mike

Hello,
I've just updated to the latest svn (5063) and now I cannot create a 
simple plot. If I just try (in ipython -pylab):
plot(rand(10))
I get:
<type 'exceptions.AttributeError'>: 'module' object has no attribute 
'masked_invalid'
The complete traceback is pasted below.
(My numpy version is 1.0.4, which indeed has no 'numpy.ma.masked_invalid'.)
Regards,
Antonio

On my Kubuntu 7.10 and WinXP with matplotlib 0.91.2 an error is raised in
