matplotlib-users Mailing List for matplotlib

As I understand it, you are having an issue with the alignment of pixels
and axis tickmarks.
Perhaps the following will help you to set up a workaround (check the
'0.5' values?)
http://sourceforge.net/mailarchive/message.php?msg_id=15509515
Maybe that helps.

I don't understand what you're asking here. Is there some unexpected 
interpolation going on? A small example might be useful to clarify if 
noone else steps forward with an answer.

Hi you all,
I have inserted a matplotlib figure into a gtk.VBox this way:
self.Box = gtk.VBox(False, 0)
self.Figure = Figure(figsize=(8, 4), facecolor=0.92, dpi=10)
self.axis=self.Figure.add_subplot(111)
self.canvas=FigureCanvasGTK(self.figure)
self.Box.pack_start(self.canvas, True, True)
The matoplotlib figure is inserted into the box this way...then i get a 
green "Frame" and a Figure area, both inside the box. However now i want to 
increase the matoplotlib figure area without increasing the box size...
How can i increase the figure area by decreasing the "frame" area?? is this 
possible??
Thanks for your answers in advance
regards
juan

Hi,
 sorry for all the newbie questions. I have looked though the 
documentation
but have not found anything on how to handle the fact that matplotlib 
takes
the array indices as the lower left corner position for the value, 
while an image
has its pixel values at the center of the pixel. Is there anything 
written on how
to handle this?
Cheers
Tommy

Is this the same under python command-line and mod_python? If you are
getting different results, it is most likely because the environment
is different in some way.

hi,
here is the output of repr(matplotlib):

Sounds like it is picking up on a file named matplotlib possibly. Try
adding "print matplotlib.__file__" after the "import matplotlib" line.
 Make sure it is the same when running from the command line and
mod_python.

This should probably be on the matplotlib list, but 0.87.1 was
compiled against numpy 0.9.5. You have to use that version. This
type of problem won't happen as much once numpy hits 1.0. 0.87.2 was
compiled against numpy 0.9.6.

Hi Ryan,
I'm sorry you are having trouble. I'm sick and am unable to help you work 
through this today. You haven't mentioned what mpl version you are using, but 
I would suggest opening an ipython shell and trying to execute the command 
via the subprocess module.

Hi all,
some students in our organisation sent me a problem with matplotlib and 
mod_python, a simple script generates a plot of temp/pressure, all works fine 
if they run it from the command-line, but if they use it from a apache web 
server they receive this :
----------------------------------------------------
Mod_python error: "PythonHandler mod_python.publisher"
Traceback (most recent call last):
 File "/usr/lib/python2.3/site-packages/mod_python/apache.py", line 299, in
HandlerDispatch
 result = object(req)
 File "/usr/lib/python2.3/site-packages/mod_python/publisher.py", line 136, 
in
handler
 result = util.apply_fs_data(object, req.form, req=req)
 File "/usr/lib/python2.3/site-packages/mod_python/util.py", line 361, in
apply_fs_data
 return object(**args)
 File "/var/www/syrso_v2/tests/essai.py", line 11, in index
AttributeError: 'module' object has no attribute 'use'
---------------------------------------------------------
where the line 11 is :
matplotlib.use('Agg')
just after a import matplotlib!
Thanks for any help

I found a thread about a recent fix to texmanager and backend_ps, but
I am still having a problem. It seems like the basic problem is that
os.system('cd c:\\temp') doesn't seem to work on windows:
C:\Documents and Settings>python
Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.1310 32 bit (Intel)] on wi=
n32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.system('cd c:\\temp')
0
>>> os.getcwd()
'C:\\Documents and Settings'
>>>
So, when texmanager tries to execute this command:
(Pdb) command
Out[3]: 'cd c:\\temp; latex -interaction=3Dnonstopmode "92ef4637f8938ad7ee6=
f05b388
9c7251.tex"'
latex can't find the file because the working directory doesn't seem
to actually change.
(This is in texmanager.py around line 200).
