It looks like revision 7020 broke this in the process of adding units
support for fill().
If I change the following lines (in the _xy_from_xy() function):
if bx:
x = self.axes.convert_xunits(x)
if by:
y = self.axes.convert_yunits(y)
back to:
if bx or by: return x, y, False
the example I posted works and the test failure I was seeing is gone. Of
course, this breaks fill() with unit-ed quantities. I'm getting a little
over my head here in terms of tracing the flow of units, so I'd love to hear
opinions on how to actually fix this. IMHO, we *really* need to standardize
on how units are handled. In some cases the axes method handles converting
units, but in this case, the Line2D object also registers for changes to
axis units so it can update itself.
