Or did you not know about it? I'd like to get as many packages as possible working with that. (and built and contributed to pythonmac.org) See this post from python-mac list: """ I've spent some time on an 10.3 box and updated the installer as a result of that. The universal python installer should now be complete, except for remaining bugs obviously. I have however not tested it on an Intel box yet. * The installer works on 10.3 and 10.4 * regrtest -uall passes on 10.3/ppc, 10.4/ppc * compiling extensions works on 10.3 * the existing (non-universal) wxPython installer installs fine and results in a working wxPython installation (on PPC only of course) on 10.3, which indicates that existing C++ extensions should work just fine with the universal build * IDLE works, including the local documentation * Profile updater works New from the previous release: * Locally installed documentation can be accessed from IDLE * Minor changes to the profile updater, and it is now also installed in /Application/MacPython 2.4 * Building extensions works on 10.3 * Various minor bugfixes There is one minor issue: the curses module doesn't work on OSX 10.3, the extension is linked to a version of libncurses that isn't available on 10.3. Please test this version and let me know of the results (both negative and positive). Unless major issues turn up we can do a golden release this weekend. That release will NOT have new icons, we can do a new release with updated icons later on.

This might have something to do with the fact that OS-X double buffers it's windows, so you need to force and update event somehow. A call to wx.Window.Refresh() and/or wx.Window.Update() might do it. However, I haven't had any problem with just using a wxClientDC in my apps, but I guess I've always been running an event loop. Maybe OS-X waits for a Idle event to update the screen. What kind of app would you have running without an event loop anyway?

Hi Ken,
Thanks for the tip. It takes very little to get this bug on my system:
>>> import pylab
>>> pylab.plot([1,2])
[<matplotlib.lines.Line2D instance at 0x32b29e0>]
>>> pylab.show()
Traceback (most recent call last):

MemoryError: _wxagg.convert_agg_to_wx_bitmap(): could not create the

The problem is in the _wxagg.so library which was compiled during
install. Looking through the _wxagg.cpp code it looks like
wxPyConstructObject(bitmap, _T("wxBitmap"),1); (line 129)
is returning null. Ken, if you want me to try something let me know
-- my guess is I'm using a different version of either the AGG
library or wx.
As an aside, does the cpp implementation run much faster than the
python implementation?

The > graph window is blank during the animation. My take on this is that wxPython-mac can't repaint the plot window if it's not running its event loop. I have attached an example of animating WXAgg plots by redrawing them from within an idle event callback. If you're building an application that uses matplotlib for visualization, you can redraw the plot from within the running application without any problems (e.g. when new data arrives). You may also want to check out the animation_blit_wx.py example, which works more or less the same way. > I also tried CocoaAgg with similar result except that it also > appears to hang.

I've been looking into this problem today but haven't been able to reproduce it myself. Could you or Onsi please send me a short script that causes the MemoryError, along information about your versions of Python, wxPython, and matplotlib? As an aside, you can disable the accelerator without editing backend_wxagg.py: import matplotlib.backends.backend_wxagg matplotlib.backends.backend_wxagg._use_accelerator(False) Ken
I got matplotlib working on my MacBook. It was surprisingly easy. NumPy installs right away (scipy is a different issue -- between gcc4.0 only and no g77 support yet...) I installed universal binaries of png, freetype, and TeX using the i- Installer. This put things in the right place, and maplotlib found them and liked them. I also installed my own version of python 2.4 -- the one that ships with the Mac has no readline, and I like readline quite a bit.. MPL seemed to install fine with both python versions, though, so that is not a big deal either way. Finally, TkAqua is pre-installed on the MacBooks, and seems to work well with MPL. It is recognized by the presintalled MacPython (2.3), and was also recognized by my own install of python 2.4 (into /usr/ local). -Rob ----- Rob Hetland, Assistant Professor Dept of Oceanography, Texas A&M University p: 979-458-0096, f: 979-845-6331 e: he...@ta..., w: http://pong.tamu.edu

I am unable to install matplot lib on my new laptop. It is an intel based Mac. Stepping throught the install I found that build_py works but build_ext breaks with what looks like a couple of link errors. Any help would be appreciated.

Hi, Alright, that was rude. And for that I appologise. Perhaps I should have counted to 10 before posting. I'm sure lots of hard work went into the port= . However, that was pretty frustrating.

Add the argument colors('b', 'r') when calling pie, i.e.
>>> pie(fracs, colors =3D ('b', 'r'), explode=3Dexplode, labels=3Dlabels,
autopct=3D'%1.1f%%', shadow=3DTrue)
Look at the docstring help(pie) for more info on the key arguments.

The irony is that warning comes in unicode exception handling :-)
Try replacing that block of code with
try:
font = ft2font.FT2Font(str(fpath))
except RuntimeError:
warnings.warn("Could not open font file %s"%fpath)
continue
except UnicodeError:
warnings.warn("Cannot handle unicode filenames")
print >> sys.stderr, 'Bad file is', fpath
continue

Greetings,
Sorry, I am new to matplotlib(0.86.1). I modifed the sample pie chart
below to report disk quota usage. But how do I specify colors? (blue
for free, and red for used)
-----------
from pylab import *
figure(1, figsize=(4,4))
ax = axes([0.1, 0.1,0.8,0.8])
labels = 'Free', 'Used'
fracs = [15,85]
figure(1)
pie(fracs, labels=labels)
figure(2, figsize=(8,8))
explode=(0.05,0)
pie(fracs, explode=explode, labels=labels, autopct='%1.1f%%', shadow=True)
savefig('pie_demo')
show()

So, it looks like what's happening is that Matplotlib is trying to cache your font files, and as it does so, it's encountered a font whose filename has unicode characters in it. This is not a problem in and of itself, and it just tries to warn you; however, the warning module is choking on the warning string that's being passed into it. So, until this gets fixed for real, a quick hack would be to edit your font_manager.py and remove the reference to the file name:
warnings.warn("Cannot handle unicode filenames")
Not as useful an error message as before, but it'll get you up and running. :)

<P>Hi</P>=0D
<P>I am new to python and want to check out matplotlib on Windows=
XP. I followed the recommondation in the installation instruction and inst=
alled the latest version of the Enthought edition of python (enthon-0.9.2).=
Then I installed matplotlib-0.87.1.win32-py2.3. When I try to import pylab=
, I get the error message shown below. I also tried the earlier version of =
matplotlib (matplotlib-0.87.win32-py2.3) with the same result.</P>=0D
<P>I will be very greatful for any hints on how to get matplotlib working o=
n Windows XP. I don't mind redoing the complete installation in another way=
if it solves the problem.</P>=0D

Packaging matplotlib is kind of hard, because there are lots of optional packages, including almost every popular GUI toolkit and TeX. If you are unhappy with the choices your packager has made you should consider compiling from source. It shouldn't be too hard on a BSD system. JDH
