It looks like the problem is that you are missing the -dev packages for 
various libraries. In your output below, wherever you see something 
about a missing header, it means you need to install a corresponding 
-dev package.

Hi,
Hoping someone can help with this... I'm trying to install in a virtual
environment created with "--no-site-packages"
I've followed all instructions re cleaning the existing .matplotlib
cache/directory and deleted .egg files etc
(virtualenv) ... $ easy_install matplotlib -- gives me an error: "command
'gcc' failed with exit status 1"
The existing components (note: all from within the virtualenv):
$ python --version --> 2.6.4
$ python -c 'import numpy; print numpy.__version__' --> 1.4.1
$ gcc --version --> 4.4.1
$ uname -a --> Linux HP-desktop 2.6.31-22-generic-pae #60-Ubuntu SMP
Thu May 27 01:40:15 UTC 2010 i686 GNU/Linux
(I'm running this on Ubuntu Karmic Koala -- please note that installing from
the Synaptic Package Manager gives me a working version which runs correctly
and as expected, using ipython -pylab etc)
This may be a question of downloading a version other than v0.99.3 but in
that case I'd not be sure which one to use(!)
I'd be really grateful for any assistance you can give....
(and finally the output/error from "easy_install matplotlib")

Ben,
The matplotlib on the other working machine is using python 2.6.4. On this machine I am using python 2.6.5.
The default python on both machines in python 2.4 but I set up python 2.6 as an alternate install in /opt/python26.

Dharhas,
Is it possible to find out which version of python was installed for your
other RHEL5 machine? I don't know if that makes a difference or not, but
RHEL5 by default uses Python 2.4.

Maybe a bug that was fixed in mpl, or in a newer version of numpy than 
you are using. Using both mpl and numpy from svn, both scripts work for me.

Hi,
I have Python 2.6 installed on RHEL5 (and Numpy 1.4.1) and am trying to install matplotlib. Installation occurs without any error messages although I do get a bunch of warnings at the end.

When I try using matplotlib I get the following error:

Any help would be appreciated. I've tried several versions of matplotlib. I also was able to get it installed on a different RHEL5 machine a while back and am not sure what is different about this machine.

John,
Thank you very much for a prompt reply.
I am using Ipython with QT4 backend for the examples. I can have animated plot (dragable vertices) for the path_editor.py, but not for the line_editor.py. My python installation is pythonxy on windows 7. Could you please tell me your installation? 
Yes, I do mean the matplotlib.widgets.Cursor, and I have version of 0.99.1. My version does not have the two lines as you mentioned.

Unfortunately, I cannot understand your problem. I have tried running
your attached example and it seems to run fine on my system (I can
drag the vertices and the line drawing is updated). Can you describe
the problem you are seeing? Could this be a version problem -- what
version of mpl are you running?

Do you mean matplotlib.widgets.Cursor? It does use the animated
property -- at least in the svn version. See the line in the __init__
function:
 if useblit:
 lineprops['animated'] = True

What you're doing sounds very similar to a Hinton diagrom (or at least the resulting image looks similar). There's an example of plotting such a diagram in the scipy cookbook: 
http://www.scipy.org/Cookbook/Matplotlib/HintonDiagrams
The implementation is pretty slow because it loops through the data and draws each square one by one. I wrote a faster alternative a while back (see attached). It uses a custom PolyCollection, which uses data units for the areas instead of figure units. Also, I just noticed there's another implementation of Hinton diagrams in the matplotlib examples folder (examples/api/hinton_demo.py). For some reason, this example doesn't appear on the website, otherwise I'd link to it.
I believe the difference between your plot and a hinton diagram is that you have a different metric for calculating the size of the squares.
-Tony

Since this data is essentially a 2 dimensional image, you may want to 
experiment with imshow.

I'm generating a plot of NxN squares, where the size of the square
corresponds to the correlation between the (i,j) point. Every (i,i)
point equals 1.0. I'm using "scatter" to do this, but the sizing
appears to be in "points" from the graphic, rather than "units" of the
two axes. Is there some way to account for this, or is there some
better way to generate this image?
# result = n x n matrix of correlations between points (i,j)
a = arange(n).repeat(n).reshape(n,n)
b = a.transpose()
scatter(a.flatten(), b.flatten(), s=result, marker='s')
You can see an example here, where N=300: (note, this is a 2.5 MB image):

Todd,
I think you are missing a "plt.show()" at the end of your code. matplotlib,
by default on most systems, does not show a plot until you tell it to using
plt.show() command.
See if that works,

I think this is a known bug (unfortunately, the bug fix does not seem
to be reflected in the maintenance version), but without a full
traceback, I'm not 100% sure.
You may use the svn version which have fixed this bug, or you may try
the workaround described in the link below (check the
clabel_monkeypatching.py).

Greetings,
 I just installed Python 2.6 (python.org), Numpy 1.4.1, and Matplotlib
0.99.1.2 all on Mac OS X 10.6 in an attempt to learn about scientific
programming in python. Go easy on me since I am a begginer. The Python and
Numpy seem to be working correctly. I can get matplotlib to make plots but
I can't get it to show images. I tried the stinkbug example in
the Matplotlib users guide documentation with no success. Errors are _NOT_
generated but neither are any results on the screen. The imread command
produces a float32 matrix that contains all 1. values so I tried creating my
own uint8 matrix with a diagnoal line. My code is below. Thanks for any
help you can provide.
# -*- coding: utf-8 -*-
from numpy import *
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
print "Numpy version: " + __version__
a = array([10,20,30,40])
print "result of a"
print a
b = arange(4)
print "result of b"
print b
c = linspace(-pi, pi, 30)
print "result of c"
print c
# this plot code works
print "plot c"
plt.plot(c)
plt.ylabel("-pi to + pi")
plt.xlabel("value of c")
plt.show()
# this image processing code does not work
print "doing image processing stuff"
# img=mpimg.imread("/Users/rovitotv/Desktop/stinkbug.png") # this does not
work
img = zeros((10, 10), dtype=uint8)
for i in range(10):
 img[i,i] = 255;
plt.imshow(img)
print "data type of img:"
print img.dtype
print "size of img:" + str(img.size)
print img

Can't you do ginput(n=1) in a while loop? Ginput needs to end at some 
point, right? Initiating a never ending loop seems like the wrong 
solution for any real-life problem.

Hi Eric,
Thanks for the tip -- I didn't realise that. I had been able to import
tkinter, but perhaps only some parts of tkinter exhibit the problem. I
worked around the issue by installing matplotlib via rpm since it is only a
little behind the curve. It may be that the issue was due to tkagg.so being
the 'last' object searched, but actually the real problem was more likely to
be the lack of some xlib library not being found. In any case, I am happy
enough with where I am now :)
Thanks for your response,
-Tennessee

It looks like your tkinter or Tk is not finding xlib; XCreateIC is an 
xlib routine. There is no direct reference to it in _tkagg.cpp.
What happens if you do
