Yeah -- the hinting doesn't seem work very well with the STIX fonts. I 
may need to expose an option in the font backend to turn hinting off.
Thanks for the report,

Just an idea: Maybe you could also auto cycle between dash types if only 
the colour and not the dash type is specified in a plot command. The 
gnuplot default would be one model, or the predefined patterns in 
CorelDraw or Inkscape etc. Personally I don't see this as a high 
priority though.

I would like to plot two or three graphs as subplots in a figure and
control the axes such that when one graph is zoomed the others are
adjusted too. I was hoping there would be a notification mechanism
which would allow me to catch a rescaling of one subplot and redraw the
others in step. Can anyone suggest a method of doing this?

I *finally* got this to work!!! 
Thanks to Werner's message, I found the culpit: the
matplotlibrc file copied to the dist directory
contains the TkAgg backend. All I had to do is to
change *that* file to say:
backend : WXAgg
Note that it's not the matplotlibrc in the installed
copy - but the one in the resulting dist directory.
In addition, I have to do a:
 set MATPLOTLIBDATA=.\mpl-data
before I start the exe file. I don't know why this is
necessary because the code for _get_data_path appears
to look at that directory by default but if I don't
set this, it can't find the data files.
In any event, it works now - after bumping head for 2
weeks!
Thanks everybody.

I am under the impression that as of mpl 0.9x there is NO specific
version dependency for wxPython. I believe there was some optimization
code which forced a dependency on wxPython 2.6 Unicode for the wxAgg
backend.

I haven't tried it with 0.91.x but with 0.90 I used a matplotlib exe
installer for Windows and I can create a distribution of my application
with py2exe which does NOT contain tkinter.

That dll should no longer be needed by matplotlib. Obviously if you use
a wxPython build you will get the it, i.e. I am on 2.8 so I have a bunch
of "wxmsw26uh???.dll" files in my dist folder.

There was another message from Stef which might be the explanation, the
default matplotlibrc file is defining TKAgg as the default backend, so
change it to the following:
backend : WXAgg
numerix : numpy # numpy, Numeric or numarray

Michael,
I am referring to the fact that there are no Windows
binaries provided for Python 2.3. If I simply copy
the matplotlib directory over to Python23, py2exe will
get confused.
I have no clue how to build it for Python23. I don't
even have any C compiler.

I might be misremembering, but I thought 0.91.2 worked with Python 2.3. 
 I don't use 2.3 every day, however. Can you send the errors that are 
produced when you build or run matplotlib 0.91.2 with Python 2.3? Or 
are you just referring to the fact that there are no Windows binaries 
provided for Python 2.3?

So, do I understand this correctly:
In order to get rid of the Tkinter problem when
building a matplotlib application using py2exe, I need
0.91.2 ver of matplotlib and use the setup.cfg file to
select the backend I want (wxpython in my case). Then
run py2exe to build the ap. Correct?
But then, as I posted earlier, this create a new
problem for me in that py2exe says it can't find
wxmsw26uh_vc.dll - even though the file exists.
What I need is a version of 0.91.2 ver of matplotlib
that works with Python 2.3 to see if that works, or I
guess I would include Tkinter with my exe?
Do I understand all these correctly?

This is a binary distribution, that is one that has already been
compiled on a different machine. This won't have the setup.cfg file,
since it is a file that is used to configure the compilation process
of matplotlib. Also this is why you can only use this distribution
with specific versions of python, wx etc.
If you choose to compile matplotlib yourself, then you have the option
of completely disabling some of the backends, which is done via a
setting in the setup.cfg file.
I am not sure how easy it is to build matplotlib on windows, but on
other platforms it is relatively straightforward.
After obtaining the source distribution, ensure you have the
requirements (including any development files) for the backends you
want. Select the backends to build in setup.cfg and run
python setup.py build
followed by
python setup.py install
Hope this at least clears up the missing setup.cfg issue...

With Stef's help, I was able to get pass the
"Matplotlib datafile not found" problem in using
py2exe and Matplotlib under Python 2.3 - but then ran
into the same Tkinter not loaded problem like he did.
After reading Stef's messages from this list, I
downloaded the latest version of Matplotlib - only to
find that Python 2.3 is no longer supported. So, I
loaded up Python 2.5 and ran the setup script for
Py2exe. Now, py2exe is unable to find
wxmsw26uh_vc.dll - eventhough I have wxPython 2.8
installed. So, I dug up a copy of wxPython 2.6 and
have that installed. The file is now there but py2exe
still can't find it.
This is very fustrating!

You can also cycle through the list matplotlib uses
 import matplotlib.lines as lines
 # filled markers
 fmarkers = lines.Line2D.filled_markers
 # all markers
 markers = lines.Line2D.markers.keys()
but this is not ideal, since lines.Line2D.markers is a dictionary and
the keys will come back un-ordered. Noone has every asked for
auto-marker cycling before, but it might be a good idea and wouldn't
be too hard to add.

Well, pylab does choose: it varies color and not the dash 
pattern in order to have distinct lines.
I think what you are wanting is something like the 
following: have pylab/pyplot cycle automatically through 
a set of preset Line2D property combinations, when an axes
plots multiple lines.
I think the answer is: this is not available in the
form you want. (Indeed, it is hard for me to imagine
agreement on "nice" choices for multiple properties.)
Of course you can do something like this::
 from itertools import cycle
 mystyles = ['r+-', 'b.--', 'go-.'] #etc
 ax1styles = cycle( mystyles )
 for x,y in data:
 ax1.plot(x, y, ax1styles.next())

Dear all,
I ran into a memory problem when trying to draw a few hundred png files 
using one imshow per file. The problem can be boiled down to the 
attached code which eats my memory very quickly until Python bombs out. 
I tried to "del" objects after their use, looked for garbage and read 
the user manual, but no luck. Did I do anything wrong or is this a 
memory leak?

That suggests that the bug is somehow related to GUI code. As John

That seems to suggest that the TkAgg backend (or Tkinter itself) is 
somehow the problem, assuming Gtk doesn't issue the same message (unlikely).
Thanks. Please let us know what other clues you can collect.

I believe John already told you this: do NOT use pylab.

IIUC, in order to have each line with distinct line style, I have to
explicitly set the line style. I want pylab to just choose them, just as
it does for colors.

Hi,
When I try to plot a time series of numpy masked array data containing 2 values and with one of them masked out my machine chokes (memory usage of more than 900 mb for the script below). The culprit seem to be my use of use the matplotlib.dates.HourLocator on the x axis.
Here is a small script illustrating the problem:
---
import numpy as npy
import pylab, matplotlib
data = npy.ma.masked_values([0, 1], 0)
dates = npy.array([731186.91666667, 731187.04166667])
#This does not help either
#dates = npy.ma.array([731186.91666667, 731187.04166667], mask=data.mask)
pylab.plot(dates, data)
majloc = matplotlib.dates.HourLocator(interval=3)

I am writting an application that evaluate curve fit and draw its plot in a
GUI , I want to draw or show the plot on the GUI not on the pop up window,
but I don't want to save the figure in first step , user just enter an order
for the curve fit and see their plots on the main window (GUI) . 
How can I use pylab for this purpose , does it return and QImage object for
exm. ?
