Great!
0.81 solves the problem I had earlier with the graph plot in PyGTK.
Thanks,

TeX. I've cleaned it up and will commit the changes momentarily
Darren

 All the binaries I provide depend on the system installed python 
(i.e. python2.3.x). These binaries are meant for people who want a 
one click installer for matplotlib in OSX that includes all needed 
dependencies. I would expect more seasoned python users to install 
the packages from pythonmac.org. I will add a note on the site.
 For the record, if anyone wants the Xcode project files for the 
freetype and libpng frameworks I provide, just ask.

Hello John & NG,
 I have just downloaded matplotlib 0.81, and I am having some problems=
with the ToolBar. The "Back" and "Forward" icons in the ToolBar2 are not
shown. The buttons are completely grey and they seem inactive. Is this th=
e
expected behavior? I think it is not. 
However, my configuration is:
- Windows XP
- wxPython 2.6.1.0
- MatPlotLib 0.81
- WXAgg backend
- ToolBar2
Other RC params are defaulted.
I notice this behavior on every demo in the examples.zip folder.
Thanks for every suggestion.
Andrea.

Ouch. Would you try pasting this over line 106 in texmanager.py?
 cleanup = glob.glob(prefix+'.*')

I don't see this problem -- are you using 0.81 or possibly a stale
CVS?
The relevant section of backend_ps is in the print_figure method
which calls
 cleanup = glob.glob(tmpname+'.*')
 for fname in cleanup: os.remove(fname)
You might want to pop in a debug ipython shell and see what tmpname
and cleanup are on your system. Do you see this in
examples/tex_demo.py ?

Hi all,
Small problem. After using pylab to run some code, having enabled the 
beautiful new latex support, when I quit pylab I'm getting a bunch of 
junk files like:

	I am posting a new 0.81 build with basemap-0.5 right now for Panther.
The 0.80 misplaced the datafiles, which explains the .matplotlibrc error
you got, Christian. I will make a Tiger build when I get home to my
laptop tonight. The current tiger build should work fine though, only
the panther one had issues.

 Jeffrey> Thanks to the developers!
The easiest way to fix this is simply change the size of your axes,
eg, 
http://matplotlib.sourceforge.net/faq.html#TEXTOVERLAP
The reason you are having trouble setting the y value of the xlabel is
that it is dynamically repositioned at draw time to make sure it is
not overlapping to tick labels. The Axis.LABELPAD parameter
determines the spacing between ticklabels and the xlabel
 ax.xaxis.LABELPAD = 10 # 5 is default
This should be exposed as an rc param, but is not currently.
JDH

Hello,
When I output my figures to postscript format the xlabel and ylabel are
a bit clipped. I'm trying to tweak the position of the xlabel using:
f=figure(0, figsize=(3,3))
[...]
contour(r, r, x, [0.5, 0.6, 0.7, 0.8, 0.9], colors='k')
xlabel("magnitude", fontsize="10")
ylabel("differential", fontsize="10")
f.get_axes()[0].get_xaxis().get_label().set_position((0.5,5)) # I tried
y's of 0.1 to 5.0
But the xlabel doesn't move one bit. Any suggestions on how I move the
xlable or otherwise fix the clipping?
I just started using matplotlib and I am very impressed. Thanks to the
developers!
best,
Jeff O'Neill

Yes, and there is a windows installer for 2.3 on the mpl website.

TeX support is untested on win32. Do you have tex installed on your
XP box? You will also need dvipng for agg (is there a dvipng port for
win32?). My guess is you will run into some troubles, which can
probably be fixed. If you are only interested in postscript, and have
tex, dvips and ghostscript, there is a fighting chance it will work.

The need to use raw strings is a python requirement and not a
matplotlib requirement
>>> s = 'this is \nu'
>>> print s
this is
u
>>>
backslash has a special meaning to python, and the only way around
this is to either hack your own python shell (eg modify ipython),
quote the slash (eg use \\) or use a raw string. Of course, if your
TeX expression has no special characters (eg no backslashes) then you
will not need the raw string quote.

I'm dumb... I took care of writing r"..." to test maths, but forgot the 
leading 'r' to test the accentuated characters... sorry, everything works 
like a charm !
By the way, when text.usetex is set to True, could one imagine to be able to

Did you remember to quote the string

I don't believe unicode works with usetex at this time -- file a

Darren,
You are correct - the way the Qt window is being draw causes the toolbar to 
overlay the plot so you end up w/ a reduced size plot. The real problem is 
that we used a QtToolbar class to implement the toolbar. The QtToolbar 
supports dragging, collapsing, and unhooking of the toolbar just like MS 
Word and other applications. This makes it very difficult to control where 
the toolbar ends up and control the final sizes of the widgets.
I think the simplest fix is change the toolbar to a collection of buttons 
and explicitly control the layout for them. It shouldn't be very difficult 
but I'm going on vacation tomorrow so we might not get to it until next week.
While we're doing this we'll also move the numeric x,y readout into the 
toolbar (it's currently below the toolbar) to save space and follow the 
pattern used in the Tk and Gtk backends.

Hello, I attached my application. I'm trying to get a plot to show up

Win32 Warning: This is the first release I've done since my windows
 build syste dies and I had to reinstall a bunch of tools and some
 version numbers in my GTK build environment changed (eg my GTK
 setup). Let me know if you encounter any problems. As always, try
 removing site-packages/matplotlib and reinstalling before reporting
 any problems
TeX support : Now you can (optionally) use TeX to handle *all* of the
 text elements in your figure with the rc param text.usetex (*Agg and
 PS only). PS support requires tex, dvips and Ghostscript 8.51
 (older versions do not work properly -- test your version with
 'gs --version'). Agg support requires tex and dvipng. A
 directory ~/.tex.cache is created where support files are cached for
 later reuse. We opted to ues TeX rather than LaTeX because it is
 faster and can do all the things we thought useful for figure text
 snippets. See http://matplotlib.sf.net/screenshots.html#tex_demo
 and http://matplotlib.sf.net/matplotlib.texmanager.html. There are
 several new rc params for configuring tex/latex support
 # use tex/latex for all text handling
 text.usetex : False 
 # tex is faster, but latex is required to use special font
 # packages. See font.latex.package
 text.tex.engine : latex 
 
 # This must be an available LaTeX font package, 
 # like 'times' or 'pslatex' ; only applies if text.usetex 
 # is true
 font.latex.package : type1cm 
 Special thanks to Darren Dale for lots of hair-pulling work
 customizing, enhancing and debugging the ps backend for LaTeX
 support.
Masked arrays: Support for masked arrays in line plots, pcolor and
 contours. There are some problems with filled contours and masked
 arrays. Thanks Eric Firing and Jeffrey Whitaker.
Contour levels arg changes: see http://matplotlib.sf.net/API_CHANGES
 for details
Byte images: Much faster imaeg loading for MxNx4 or MxNx3 UInt8
 images, which bypasses the memory and CPU intensive integer/floating
 point conversions. Nicolas Girard
New image resize options interpolation options. New values for the
 interp kwarg are
 
 'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36',
 'hanning', 'hamming', 'hermite', 'kaiser', 'quadric', 'catrom',
 'gaussian', 'bessel', 'mitchell', 'sinc', 'lanczos', 'blackman'
 See help(imshow) for details, particularly the interpolation,
 filternorm and filterrad kwargs.
Text and dashes - Daishi Harada contributed a patch for connecting
 text to points with lines. See examples/dashpointlabel.py and
 examples/dashtick.py
Fast markers on win32: The marker cache optimization is finally
 available for win32, after an agg bug was found and fixed (thanks
 Maxim!). Line marker plots should be considerably faster now on
 win32.
set deprecated: use setp instead; a simple, mostly braindead,
 conversion script is provided below
Qt in ipython/pylab: You can now use qt in ipython pylab mode. Thanks
 Fernando Perez and the Orsay team!
Agg wrapper proper: Started work on a proper agg wrapper to expose
 more general agg functionality in mpl. See examples/agg_test.py.
 Lots of wrapping remains to be done.
New scalar formatter: Darren Dale did a lot of work to make scalar
 formatting smarter in pathalogical cases. See
 examples/newscalarformatter_demo.py
Small features: linewidth and faceted kwarg to scatter to control
 edgewidth and color, autolegending now inspects line segments in
 addition to vertices, upgraded to agg23, new example showing how to
 use line collections examples/line_collection.py, fixed antialiased
 property setting in agg, added a postscript papersize rc option,
 added an example showing how to embed mpl in a qt app
 examples/embedding_in_qt.py, arrow keys now exposed in mpl's GUI
 neutral event handling, added "among" kwarg to axes picker function
 to limit picks, added autoscale_on property to Axes to control
 whether or not autoscaling is done.
Bug fixes: fixed a contour masked array bug, contour memory leak

Hi all,
I'd like to write a function which, for a given data, plots it in 3 subplots 
the following way:
 +-------+ +-------+ +-------+
 | | | | | |
 | | | | | |
 | | | | | |
 | | | | | |
 | A | | B | | C |
 | | | | | |
 | | | | | |
 | | | | | |
 | | | | | |
 +-------+ +-------+ +-------+
 0 1 0 0.1 0.9 1
where A,B and C should be the same figure ; only the x axis range should 
differ.
As generating A is not straightforward, it would be useful in this case to be 
able to duplicate A as B and A as C, then to change B and C's x axis.
Have you any idea on how to do this ? 
I must confess I'd also find it useful if one could tell me how to change only 
but the x axis range... I know the axis() function but it seems you must 
provide both x & y ranges to this function so that's not what I need ; I also 
tried
 gcf().axes[0].set_xlim((0,0.1))
but whithout success...
Thanks in advance,
cheers,
nicolas
