matplotlib-users Mailing List for matplotlib

 I was just working on the same problem when I saw 
 your post. There is a way to do this without having to hack
 code. As I myself learned from this list, the ticks
 are markers. The trick is to set the markeredgewidth
 of the ticks. For example:
 plot1 = subplot(111,axisbg='w')
 set(plot1.get_xticklines() + plot1.get_yticklines() , mew=3.0)
 This should do the trick.

Is there a way to set the size of a polar plot (similar to the axis argument
to the plot command for a rectangular plot)? Thanks.

Hi all,
This is a quick release in advance of scipy this Thursday. I'm short
on time right now so I'll just paste in the CHANGELOG since the last
release. I also have not been able to make a binary build for
python2.3 on win32, but there is a 2.4 version. I'll get this all
sorted out next week.
2005年09月14日 Added a new 'resize_event' which triggers a callback with a
 backend_bases.ResizeEvent object. Not implemented on all
 backends - JDH
2005年09月14日 font_manager.py: removed chkfontpath from x11FontDirectory() - SC

2005年09月09日 Added support for auto canvas resizing with
 fig.set_figsize_inches(9,5,forward=True) # inches
 OR
 fig.resize(400,300) # pixels
2005年09月07日 figure.py: update Figure.draw() to use the updated
 renderer.draw_image() so that examples/figimage_demo.py works again.

 exists) - SC

Hi all,
I have switched to python2.4 and matplotlib does not install fine !
When doing : import pylab 
I get :
 >>> import pylab
 
 The import of the numeric version of the _transforms module,
 _nc_transforms, failed. This is is either because numeric was
 unavailable when matplotlib was compiled, because a dependency
 of
 _nc_transforms could not be satisfied, or because the build flag
 for
 this module was turned off in setup.py. If it appears that
 _nc_transforms was not built, make sure you have a working copy
 of
 numeric and then re-install matplotlib. Otherwise, the following
 traceback gives more details:
 
 Traceback (most recent call last):
 File "<stdin>", line 1, in ?
 File "/usr/lib/python2.4/site-packages/pylab.py", line 1, in ?

 from axes import Axes, PolarAxes

 from matplotlib._nc_transforms import *
 ImportError: /usr/lib/python2.4/site-
 packages/matplotlib/_nc_transforms.so: undefined symbol:
 _ZNSt24__default_alloc_templateILb1ELi0EE8allocateEj
 
However, Numeric24 is installed (and was installed before matplotlib),
and import Numeric is OK.
BTW, I use gcc33... but i don't think it matters a lot, does it ?l
Any idea is welcome !
