matplotlib-users Mailing List for matplotlib

Dear ALL,

I received a report of a Mac OS X user who attempted to run my
recently released biodiversity mapping software based on MPL/Basemap
and wxPython.

As I have no access to an Apple Macintosh machine nor have much
experience with that OS anyway, I am posting the error report here in
the hope some of you nice guys can help.

I am also posting the steps the user followed in order to install the
software on the Mac OS X. From the error log, it looks that there may
be some issue with the version fo MPL he is using (which is the one
packaged with Enthought Python).

Thanks in advance for any assistance you can provide.

With best regards,

========================
Getting the package to work:

1. need networkx
download .egg file from here:
http://pypi.python.org/pypi/networkx/

install with:
easy_install /Users/nick/Desktop/downloads/networkx-0.99-py2.5.egg


(get easy_install from here:
http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install
http://peak.telecommunity.com/DevCenter/EasyInstall#downloading-and-installing-a-package
)


2. need mpl_toolkits.basemap:

download source from here:
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=142792/&abmode=1

install instructions:
http://matplotlib.sourceforge.net/basemap/doc/html/users/installing.html



2.1 - download & unpack
cd /Users/nick/Desktop/downloads/basemap-0.99.3/
cd geos-2.2.3
export GEOS_DIR=/usr/local
./configure --prefix=$GEOS_DIR
make
sudo make install
cd ..
python setup.py install


in python:
mpl_toolkits.basemap import Basemap

need matplotlib 0.98 not 0.91

in python:
mpl_toolkits.basemap import Basemap

need matplotlib 0.98 not 0.91


2.2 - download updated version
http://sourceforge.net/project/showfiles.php?group_id=80706

download basemap:
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=142792&release_id=653688

double click:
matplotlib-0.98.5.2-py2.5-macosx10.5.mpkg



3. that didn't work, installing WHOLE NEW VERSION of Enthought which
has matplotlib 0.98
http://www.enthought.com/products/epddownload.php


redo install of basemap:
http://matplotlib.sourceforge.net/basemap/doc/html/users/installing.html

cd /Users/nick/Desktop/downloads/basemap-0.99.3/
cd geos-2.2.3
export GEOS_DIR=/usr/local
./configure --prefix=$GEOS_DIR
make
sudo make install
cd ..
python setup.py install


in python:
mpl_toolkits.basemap import Basemap
invalid syntax

from mpl_toolkits.basemap import Basemap
this works!


test:
cd examples
python simpletest.py
python run_all.py

basemap: most things worked, but not all.  Neat mapping capability!
Probably slow though...
========================


Basically, the most important thing was re-installing the newest
version of Enthought, so as to get matplotlib 0.98, and then
installing basemap.

So I got all of that working, then ran 'python Croizat.py' and got the
following error which has me stymied:

Hi,

I'm experiencing a weird problem with the bounding box of my eps files.
I have a script that produces my plots and saves them as eps files.
For some reason the x coordinate of the bounding box is negative.

The bounding box of the files are: %%BoundingBox: -54 36 666 756

Then, when I try to print or show these files with gv they are clipped at
the left side.
I found the translate command on the EPS file format specification, so I
added: 54 0 translate to the eps header.
Everything looked ok until I tried to include these files in a tex/ps
document. Now they get clipped on the right side! I've tried and googled
several things and can't get it to work.

Does anyone knows what is going on?

Thanks in advance

Ramiro

Got it working using tkAgg by recompiling matplotlib from source.

I have switched between python2.5 and 2.6, so maybe I've messed up the
installation somehow, and it's not looking for things in the right
directories.

I fiddled around with the versions of cairo and pycairo, and got them to
match but still got errors:

>>> import gtk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/__init__.py",
line 48, in <module>
    from gtk import _gtk
ImportError: /usr/lib64/libcairo.so.2: undefined symbol:
pixman_region32_rectangles

Also using tk doesn't work either:

I haven't seen this before, but it definitely looks like an installation 
problem with pygtk and/or pycairo, since it fails without matplotlib 
even entering into it.  In particular, it looks like a possible mismatch 
between the versions of pycairo and cairo.  Is everything installed from 
your distro's packages, or did you build this yourself?

Until "import gtk" works, there's little matplotlib can do, 
unfortunately.  You may want to head over to the pygtk list for help if 
you're still stuck.

Probably there are none for the version of Ubuntu you're using but
there are newer packages in Ubuntu[1].

I'm not a Ubuntu guru, but you seem to be rather old in version, I
suggest, given the short release period, to keep your system
up-to-date to the current version (not 8.10 I think) and there there
are newer binary packages too[2].

Since this was a windows platform, I am curious if this has something
to do with the differences in newline '\r\n' handling and python
binary file handling between windows and unix platforms (there is no
difference between file(somefile, 'wb') and file(somefile, 'w') on
linux but they are different on windows)

I've removed the "%%EOF" comment from the embedded font in SVN (your 
suggested change).  I'm still stumped as to why this matters, but it 
should be benign.

Thank you for the information.  I figured out that using pylab works.  I
would rather use a current version.  I tried to find the version you
mentioned in a deb package for Ubuntu but it doesn't seem to exist.  Do you
know why or where can I get it?

Thank you again.

In the early releases of matplotlib, the procedural plotting interface
of matplotlib resided in "pylab", which also mixed in a lot of
numerical routines from numpy and other places.  *After* the release
of 0.90.1, Eric Firing reorganized the plotting functions into a
separate module "matplotlib.pyplot" so people could access them w/o
having to get all of the numpy functions in the same namespace.  See

  http://matplotlib.sourceforge.net/faq/usage_faq.html#matplotlib-pylab-and-pyplot-how-are-they-related

The version you are using is 2 years old, so you may want to consider
upgrading.  But you can get the same functionality with 0.90.1 by
simply

   >>> import pylab as plt

instead of

   >>> import matplotlib.pyplot as plt

Yes, I did have an typo in when reporting the problem, it should be pyplot
not plot.  However, the problem is with pyplot anyway.  The version of
matplotlib is 0.90.1 as shown here:

  >>> import matplotlib.pyplot as plt
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: No module named pyplot
  >>> import matplotlib
  >>> print matplotlib.__version__
  0.90.1
  >>> 

If this version is to young then how can I get Ubuntu to load a later
version?

Thank you for your response.  Again, I appreciate any help anyone could
provide.

You can't modify that file - but if you can find an ESRI shapefile that 
has the coastlines for just the area you're interested in you can use that.

here you wrote "plot" not "pyplot": might this be the problem?

What version of matplotlib do you have?

	import matplotlib
	print matplotlib.__version__

Hi,

I am using Ubuntu Gutsy 7.10 and want to use matplotlib.pyplot but when I
execute:

> import matplotlib.pyplot as plt

I get:

>>> import matplotlib.plot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named plot

I installed matplotlib using synaptic.

I found another reference to this problem on Google but no solution.

I cannot find pyplot.py anywhere on my disk.  I can import matplotlib by
itself.

Is there another Ubuntu package I should install?  Is anyone working on a
fix to the matplotlib ubuntu packages?  If so, then does anyone know when
this may be resolved?

Any advice would be appreciated.

Thank you,
Marc
