matplotlib-users Mailing List for matplotlib

In a plot window (using Tkagg). just right of the menu the x and y  
positions
of the pointer is shown when the mouse is in the window. Since I am  
using
small windows this will change the size of the window. Is there a way  
to set
the format or remove this text?

Cheers
Tommy

I changed the qt backends to create a QApplication in show() rather than at 
the time of module import. I also updated the embedding_in_qt* examples. 
Samuel, as of svn 2711, you are free to create your QApplication *after* you 
import backend_qt(4).

P.S.- For anyone who is interested, I'd recommend "C++ GUI Programming with Qt 
4" (available at Amazon). I'm not an experienced C++ programmer, but the book 
has an excellent (and brief) introduction to C++ in the appendix, and is easy 
enough to understand for anyone who wants to work with PyQt4.

Hi All,

I'm using matplotlib (with agg backends) from recent svn:

In [63]: matplotlib.__version__
Out[63]: '0.87.4'

and I can't seem to get contour() or contourf() to utilize the
alpha keyword.  No matter what value I set, alpha=1.0 on the
output.  Alpha in general works fine, as the scatter_demo2.py
example gives very nicely alpha-channeled output.

Any ideas?  Thanks a bunch,

Scott

David,

This are not any WxMpl mailing lists at this time.  If you have a  
problem or need to ask some questions, please send me an email.

For WxMpl questions, this list is currently the closest thing to a  
right place.  I can also be contacted directly via email.

This is a bug that has been fixed in the wxmpl subversion  
repository.  I should probably make another release so no one else  
has the same problem.

You can grab the latest wxmpl.py from
