matplotlib-users Mailing List for matplotlib

Hi,

first time user, first time installer...

Is there a howto for matplotlib installation on redhat 7.3/as2.1 & as3.0?

I'm trying to install matplotlib on these platforms and am running into 
a seemingly endless list of dependancies for python2.2, numarray:

just on the 7.3 side,
  - freetype >= 2.1.7 is needed, but rh has 2.0.9-2.
  - pygtk >= 1.99.16 needed, rh has 1.99.8-7.
  - pygtk 2.2.0 needs glib >= 2.2.0, redhat has 1.2.10-5,
  - pygtk 1.99.16 compiles, but I get error "ImportError: 
/usr/lib/libpangoxft-1.0.so.0 undefinded symbol: FT_Seek_Stream", which 
I haven't tracked down just yet...
  - the line "inf = infty = Infinity = _ieee.inf" in na_imports.py fails 
to find 'inf' in '_ieee', but commenting it out works fine.
  - While the install webpage says I only need freetype,libpng,zlib to 
compile, I get runtime complaints on import of matplotlib.matlab * 
(running simple_plot.py) about missing image libraries if I don't turn 
the BUILD_IMAGE flag on.


This is all way too difficult me as I'm not looking forward to upgrading 
so many packages across our production machines...am I missing something 
obvious?  Perhaps an older version of matplotlib known to work on this 
redhat?  I'm just using it for simple time-series plots, real-time and 
to some file (png, gif, ps, pdf...).


thanks in advance for any help,

Darrell

Are you sure the rc file you are editing is being found and loaded.
Where are you placing the rc file?  The search order for rc is

     * current working dir
     * environ var MATPLOTLIBRC
     * HOME/.matplotlibrc
     * MATPLOTLIBDATA/.matplotlibrc

Yes, this is fixed in CVS, thanks.

Sorry for all your troubles.  There are a couple of additional hints
that may help you get your environment configured properly.  First,
run a test script, eg examples/simple_plot.py with the
--verbose-helpful flag.  This will give you information at runtime
about what resources matplotlib is loading, eg what data path
matplotlib is using, what rc file etc.

As indicated above, there are two additional things you can do to help
matplotlib find it's data files.  One, you can place an rc file in
your working directory if you don't want to use a home directory for
it.  Secondly, you can set the environment variable MATPLOTLIBDATA as
described at http://matplotlib.sourceforge.net/installing.html.

Hopefully with some combination of the extra ways to point matplotlib
to its data files and the extra diagnostic information from the
verbose flag, you can get this working.

Assuming /usr/local/python/python-2.3-FC2/share/matplotlib exists and
contains the files you referred to above, this is the dir that you
would set MATPLOTLIBDATA to point to.

If you find the magic combination, please post or for future googlers.
Or if you have any suggestions for documentation improvement let me
know.

Hi -

I installed matplotlib into an alternative directory (using 
--home=/usr/local/python/python-2.3-FC2).

I edited my .matplotlibrc file to set the data directory to 
/usr/local/python/python-2.3-FC2/share/matplotlib, but it doesn't seem to 
work:

   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/backends/__init__.py", line 20, in ?
     globals(),locals(),[backend_name])
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/backends/backend_gtkagg.py", line 9, in ?
     from matplotlib.figure import Figure
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/figure.py", line 3, in ?
     from axes import Axes, Subplot, PolarSubplot, PolarAxes
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/axes.py", line 10, in ?
     from axis import XAxis, YAxis
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/axis.py", line 20, in ?
     from font_manager import FontProperties
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/font_manager.py", line 942, in ?
     fontManager = FontManager()
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/font_manager.py", line 791, in __init__
     rebuild()
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/font_manager.py", line 779, in rebuild
     self.ttfdict = createFontDict(self.ttffiles)
   File "/usr/local/python/python-2.3-FC2//lib/python/matplotlib/font_manager.py", line 411, in createFontDict
     verbose.report_error("Could not open font file", fpath)
TypeError: report_error() takes exactly 2 arguments (3 given)

(BTW the bottom appears to be a bug - report_error should be given 3 
arguments)

I've also tried specifiying the /usr/local/python/python-2.3-FC2/ and 
/usr/local/python/python-2.3-FC2/share, but neither work.

Is there any reason why the location of the data directory can't be put 
into matplotlib when it is installed? This would be much more convenient. 
It would also be nice if matplotlib can find the location of .matplotlibrc 
if there isn't one in the user's directory. When sing an alternate 
installation directory, it can't find one at the moment.

Hello,

 

while I was trying to build the matplotlib 0.64 with python 2.4 on my win xp machine

a lot of errors occurred. Has anyone managed to install it under these conditions?

Or is there any location I can download the binaries for python 2.4 and win xp?

 

Any help would be appreciated.

 

Thanks,

Frederik
