This is a sample showing how to embed a matplotlib figure in a wxPanel,
and update the contents whenever a timer event occurs. It is inspired
by the GTK script dynamic_demo.py, by John Hunter (should be supplied with
this file) but I have assumed that you may wish to embed a figure inside
your own arbitrary frame, which makes the code slightly more complicated.
It goes without saying that you can update the display on any event, not
just a timer...
Should you require a toolbar and navigation, inspire yourself from
embedding_in_wx.py, which provides these features.
Modification History:
$Log$
Revision 1.7 2005/06/15 20:24:56 jdh2358
syncing for 82
Revision 1.6 2004/10/26 18:08:13 astraw
Converted to use new NavigationToolbar2 (from old Toolbar).
Revision 1.5 2004/06/26 06:37:20 astraw
Trivial bugfix to eliminate IndexError
Revision 1.4 2004/05/03 12:12:26 jdh2358
added bang header to examples
Revision 1.3 2004/03/08 22:17:20 jdh2358
* Fixed embedding_in_wx and dynamic_demo_wx examples
* Ported build to darwin
* Tk:
removed default figman=None from nav toolbar since it needs the
figman
fixed close bug
small changes to aid darwin build
Revision 1.2 2004/02/26 20:22:58 jaytmiller
Added the "numerix" Numeric/numarray selector module enabling matplotlib
to work with either numarray or Numeric. See matplotlib.numerix.__doc__.
Revision 1.1 2003/12/30 17:22:09 jodonoghue
First version of dynamic_demo for backend_wx
