Derrick: Sorry, I missed that. I'm at a loss then, since I can't
reproduce that error on any of the systems I have access too (Macos x,
linux 32 bit, and ia64). I wonder if anyone else out there with x86_64
would be willing to try the latest basemap from CVS?

Hi,
The current boxplot function in matplotlib does not appear to support
labels for individual boxplots, if there are several on the same plot.
I know I can manually add labels, but would prefer not to do so, since
I am trying to automate the process of graph creation as much as
possible.
Is there perhaps something that I am overlooking, that would make this
possible?
I'm currently using matplotlib 0.82, as packaged by Debian. Sorry, I
know this is out of date, but it is easier to use the Debian package.
Thanks in advance for any suggestions.
 Faheem.

is something like this ready-made in matplotlib,
corresponding to the load() function?:
 save('output.csv', data, fmt='%1.4e', delimiter=';')

Hi there - anyone know of a ubuntu debian repository that has matplotlib? Its not in the 'universe' repository

Hey Darren, 
Looks like this old favorite:
 http://matplotlib.sourceforge.net/faq.html#PYGTK24
JDH

I would like to build mpl on a system running Redhat Enterprise Linux 4,
which includes Python-2.3.4, gtk-2.4 and pygtk-2.4, all packages are up to
date with the RHEL repositories.
I've run into a problem during the build, and would like to ask for
suggestions.
Thanks,
Darren

Jeff, Actually, in the long and drawn out email describing the various

numpy. I haven't tried numarray yet. The version info is below...
numpy: 0.9.2

We haven't put support in yet, but it is very easy to do. I will add
this to cvs very soon. For now:
Edit basemap's setup.py and replace "from distutils.core import setup"
with "from setuptools import setup".
In BOTH mpl's and basemap's setup.py file add this option to the setup
method, "namespace_packages =3D 'matplotlib.toolkits'".
Both mpl and basemap should be installed as eggs. The namespace is
how setuptools know separate packages share... a namespace.
Let us know if you run into problems.

Hi folks,
I recently installed setuptools, and now whenever I build mpl
(I'm using 0.86), it gets installed in site-packages as an egg.
Fine, as far as use within python is concerned it works just
as before. But I just tried to install basemap, and the
installer puts it in site-packages in a new matplotlib directory
(i.e., not in the matplotlib...egg directory). If I try
to use it, I get an import error because it's not found 
in the egg (which must the first place Python finds mpl).
How can I properly install an mpl toolkit in the egg scenario;
or if there is no easy way, how can I "turn off" eggs so when
I build mpl it makes a normal install. Just deleting the
build directory (and the egg from site-packages) and rebuilding
from scratch didn't do it.
Thanks,
Tom

The LaTeX low level font commands are now accessible using either =
rcParams[...] or the `matplotlibrc' file instead of a seperate input =
file as proposed previously.=20
e.g. in you pylab script file:
rcParams['latex.font.uselowlevel']=3D'True'
rcParams['latex.font.size']=3D'12' # Fontsize, e.g. 10, 11, 12, =
...
rcParams['latex.font.baselineskip']=3D'14'# Baselineskip - usually 1.2 x =
Fontsize
rcParams['latex.font.encoding']=3D'T1' # T1 - Latin 1, etc.
rcParams['latex.font.family']=3D'phv' # cmr - Computer Modern Roman, =
ptm - Times-Roman, phv - Helvetica, etc.
rcParams['latex.font.series']=3D'm' # m - Medium, b - Bold, bc - =
Bold Condensed, bx - Bold Expanded
rcParams['latex.font.shape']=3D'n' # n - Upright (Normal), it - =
Italic, sl - Slanted,
 # sc - Small Caps, ui - Upright =
Italics, ol - Outline
To bypass a specific low level command, set the rc parameter to an empty =
string, e.g.
rcParams['latex.font.size']=3D'' # Fontsize, e.g. 10, 11, 12, =
...
The default fontsize will now be used.
The code added to `backend_ps.py' and `texmanager.py' are basically:
...
 fontcmd =3D ''
 if rcParams['latex.font.uselowlevel'] =3D=3D 'True':
 if rcParams['latex.font.size'] and =
rcParams['latex.font.baselineskip']:
 fontcmd +=3D r'\fontsize{%s}{%s}' % =
(rcParams['latex.font.size'], rcParams['latex.font.baselineskip'])
 if rcParams['latex.font.encoding']:
 fontcmd +=3D r'\fontencoding{%s}'% =
rcParams['latex.font.encoding']
 if rcParams['latex.font.family']:
 fontcmd +=3D r'\fontfamily{%s}'% =
rcParams['latex.font.family']
 if rcParams['latex.font.series']:
 fontcmd +=3D r'\fontseries{%s}'% =
rcParams['latex.font.series']
 if rcParams['latex.font.shape']:
 fontcmd +=3D r'\fontshape{%s}'% =
rcParams['latex.font.shape']
 fontcmd +=3D r'\selectfont '
...
(or see attached)
The validations to the added param keys in `__init__.py' maybe needs =
some more work...

How do I go about doing that?
I have never used CVS before. (Only RCS for my own stuff.)
I have installed TortoiseCSV (yes, unfortunately I am a win32 user...), =
but how do I proceed from here...
I started reading the part `Developer CVS Access via SSH' (instead of =
`Anonymous CVS Access')
I have created a SF login, but can't get past the:
`Log in to SourceForge.net' admin page...
