ditto.
I sent an email concerning this earlier, but it hasn't appeared.

Which LaTeX distribution are you using on windows?  TexLive handles
paths much more poorly than MikTeX.

Finally I changed in matplotlib/__init__.py the evaluation of $HOME to a 
path without spaces because all files are transfered to 
$HOME.matplotlib/tex.cache/ instead of $TEMP

I also had to change in texmanager.py some of the "%s" to %s

I think someone with more experience in programming should check the 
path handling on windows (regarding to spaces in the path)

I would also suggest that temporary files go into a path which is based 
on $TMP.

I noticed that I get the error only when I write on a FAT32 partition 
that I use to exchange file with Windows. Writing on my /home ext3 
partition gives no error.
I guess MPL is trying to put some attribute on the saved file that is 
not supported by FAT32.

Down here there's the "xmode verbose" traceback

One colorbar should have blue lines the other one should have black

so I tried both. 'drawedges=True' works and I get black lines.
'drawedges=False' doesn't work for me and I get blue lines.

Yes I know, I thought this would illustrate the behaviour I get a bit
better.

I'm using the GTK backend.
I tried the GTKAgg and WXAgg backends and there it works.

I just checked and another error I get is also related to the GTK
backend. imshow() always has one pixel errors at different edges. But
with GTKAgg it is aliased away.


Best regards,
Nikolai

Hi Darren,

I will try to change my temp path later this day. But I also think, that 
  one problem comes from the fact that I have installed Python not on my 
C: drive.

I'm sorry Wolfgang, but I don't have access to a windows computer at home, and 
my next two weeks at work are literally booked from dawn to dusk. I don't 
know when I'll get a chance to look into this again. Hopefully someone else 
on the list can offer some suggestions.

Hi,

with some manual adjustments in texmanager.py I get the first tex file 
processed to an dvi and both files (tex + dvi) are copied into this folder:
C:\Documents and Settings\s0167070\.matplotlib\tex.cache

but now dvipng refuses to do its job:

     if exit_status: raise RuntimeError('dvipng was not able to \
RuntimeError: dvipng was not able to process the flowing file:
C:\Documents and 
Settings\s0167070\.matplotlib\tex.cache\3bb1bc57100b0c65915bdda3a1f60dae.dvi
Here is the full report generated by dvipng:

Settings\s0167070\.matplotlib\tex.cache\3bb1bc57100b0c65915bdda3a1f60dae.dvi": 
No such file or directory

It seems that the spaces in the temp path produce the error. Is there a 
way to change the temp dir (beneath in system settings of XP)?

Thanks
Wolfgang

and the answer is: legend().draw_frame(0)

problem solved

Hi,

how can I switch off the frame of the legend?

Thanks
Wolfgang

Please try changing line 191 in texmanager.py from this:

command = 'cd %s; latex -interaction=nonstopmode "%s"'\

to this:

command = 'cd "%s"; latex -interaction=nonstopmode "%s"'\

Also, backens/backend_ps.py line 1274 needs to be changed:

command = 'cd "%s"; latex -interaction=nonstopmode "%s"'%(gettempdir(), 
latexfile)

as does line 1287:

command = 'cd "%s"; dvips -o "%s" "%s"' % (gettempdir(), psfile, dvifile)

These changes are in svn 2465. Sorry for the trouble.

Darren

there is no output from latex produced as it can't find the file!

Hope that someone has a clue about whats going wrong here!

Thanks

Please set verbose.level : debug in your matplotlibrc file, and then rerun 
your script and post the full output, including the full latex report.

Hi,

problem is solved. It seems that the file got corrupted during the first 
download and all further tries to download it again referred to the 
cached file. The solution simply was to empty the file cache.

Sorry for causing trouble
Wolfgang

Wolfgang:  Works fine for me - I suggest trying another SF mirror.  Do 
you remember which one you downloaded the corrupt file from?

Hi,

I'm quite new to python and matplotlib, but at least simple graphs work 
already. But now I tried to use tex for processing labels.

tex, latex, dvipng and ghostscript are in my path. A manual tex-run on 
the tex file produces a dvi file.

Any help is appreciated
Wolfgang

PS: I'm runnin on WinXP prof

I tried to download basemap 0.9 from sourceforge but during unzipping I 
get an crc error. Can anybody else test the file from sf?

Thanks

Eric is correct - griddata should work with either Numeric/numarray/numpy.

The matplotlib.numerix layer is fairly robust, and there is no reason
to drop support for Numeric of numarray in the near term or develop
bits of matplotlib that are numpy only.  While I heartily encourage
people transition to numpy ASAP, I would like to continue full support
for both Numeric and numarray until people who have a large commitment
to one package or another have had time to convert; large institutions
with large code bases, limited man-power and higher priorities will
take their time converting.  Note that the Space Telescope Science
Institute, who developed numarray and is still in the process of
porting to numpy, makes heavy use of matplotlib and developed
significant components of it, including the tkagg backend, the font
manager, contouring and the numerix layer itself.  

Usually, if something doesn't work with all three packages, it's
because a developer forgot to test and can be fixed in a few minutes
of work.

backend_agg and backend_wxagg both use the same underlying pixel
buffer, so you should be able to get uniformity between them.  Note,
matplotlib has a different default dpi setting for figures for display
and saving, and you might want to try forcing them to be the same with

dpi = 72
fig = figure(dpi=dpi)
plot something
fig.savefig(somefile, dpi=dpi)

If that doesn't help, the only other possibility is that the
PIXELS_PER_INCH defaults are getting you screwed up.  This was
included for display devices which have a different number of pixels
per inch; see
http://groups.google.com/groups?q=screen+dpi+x11&hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&selm=7077.26e81ad5%40swift.cs.tcd.ie&rnum=5
for some info about screen dpi.  I vaguely recall that there was some
good reason for including the pixels_per_inch constant *and* dpi,, but
now I suspect the system may be overdetermined and we should drop this
and just use the dpi setting.  In any case, each backend defines their
own (see src/_backend_wxagg.cpp and backends/backend_wx.py) and the
defaults are different in backend_agg and backend_wx). 


If the dpi suggestion above doesn't work, try setting PIXELS_PER_INCH
in backend_wx.py to 72.

"should" but sometimes perhaps it's too hard to do this. One solution, if t=
he=20
function won't work with anything else than numpy, is to print a=20
warning/error message for this specific function. That will push people=20
towards numpy?

Yes, I'm alive and well, thank you :).
It's on my radar now.
