Merged revisions 3909-3924 via svnmerge from

r3910 | jrevans | 2007-10-03 18:23:48 -0400 (Wed, 03 Oct 2007) | 4 lines
Moved a couple of routines from the Agg version of the FigureCanvas to the base qt
version where they belong. Added a couple of overloaded qt methods that should be
there and reduce having to inherit when embedding in another QWidget.
........
r3911 | jrevans | 2007-10-03 19:05:30 -0400 (Wed, 03 Oct 2007) | 3 lines
Removed an erroneous print statment in backend_qt.py.
Added a feature to keep track of axes inversions.
........
r3916 | sameerd | 2007-10-04 17:39:07 -0400 (Thu, 04 Oct 2007) | 3 lines
Fix for "NameError: global name 'ones' is not defined"
........
r3917 | jrevans | 2007-10-04 18:13:18 -0400 (Thu, 04 Oct 2007) | 5 lines
axes.py: Reverted get/set xlim/ylim methods to original state
Added get/set xbound/ybound to handle axes inversion maintenance
Removed inverted axes flags
patches.py: Added some logic to xform an Ellipse angle as per the Ellipse's transformation.
........
r3918 | efiring | 2007-10-05 02:18:25 -0400 (Fri, 05 Oct 2007) | 2 lines
Minor cleanup of arguments and docstring in contour
........
r3919 | efiring | 2007-10-05 02:58:15 -0400 (Fri, 05 Oct 2007) | 2 lines
Tweaked automatic contour level calculation
........
r3920 | jrevans | 2007-10-05 12:29:17 -0400 (Fri, 05 Oct 2007) | 2 lines
Fixed a typo in the Ellipse code that was causing the ellipse angle to go in the wrong direction. When I was testing I had forgotten to turn off the axes inversion test.
........
r3921 | jrevans | 2007-10-05 13:01:36 -0400 (Fri, 05 Oct 2007) | 2 lines
Fixed an error in calculating the mid-point of a bar since the values are now lists and not arrays, they need to be iterated to perform the arithmetic.
........
r3923 | dsdale | 2007-10-05 14:56:10 -0400 (Fri, 05 Oct 2007) | 1 line
