matplotlib-devel Mailing List for matplotlib

I'm using basemap to plot a dataset* that has longitude values like so:
lon = [0, 2, 4, ..., 356, 358]
I'd like to use Basemap.shiftgrid to transform the longitudes and data
to the -180, 180 interval, but I get 'ValueError, cyclic point not
included' since 360 isn't among the longitudes.
Attached is a version of shiftgrid that attempts to handle the
non-cyclic case. There are pseudo-unit-tests that demonstrate the
cyclic and non-cyclic case for a 180 degree shift.
Thanks,
Eric

It sounds to me like this is caused by a glitch in the release process, 
in which a version of setup.cfg was included accidentally. If you have 
such a file, try deleting it.

You need to install PyQt4

Hi,
just a remark.
qt4 does not get detected on centos5.3 (probably the same on centos5.x
and redhat 5.x). Installed are qt4-4.2.1* packages and qt4-devel-4.2.1*
packages.

Hi,
on a fresh CentOS5.3 with SciPy installed from repository
http://software.opensuse.org/download/home:/ashigabou/ and additional
packages
	freetype-devel-2.*
 libpng-devel-1.*
 pygtk2-devel
 gtk2-devel
the matplotlib-setup script "setup.py" fails with error:
...
 wxPython: no
 * wxPython not found
Traceback (most recent call last):
 File "setup.py", line 146, in ?
 import wx
ImportError: No module named wx
This does _not_ happen if I use the 0.99.0 archive (on the _same_ machine).
It seems as if the setup.py 0.99.1.1 only runs if the optional package
wx is installed.
Greetings
Jens

This is probably a bug in the pdf backend. Ghostscript 8.62 complains
with "Error: /nocurrentpoint in --run--". This suggests that an "m"
(moveto) command is missing somewhere. I'm too busy to debug this today,
but please file a bug in the tracker.
