I have confirmed the problem with current svn; I will work on it.

The version I'm using is:

__version__  = '0.88'
__revision__ = '$Revision: 2251 $'
__date__     = '$Date: 2006-04-03 07:57:51 -0700 (Mon, 03 Apr 2006) $'

The following script demonstrates a problem in autoscaling. Not all the data
ends up in the window, when using set_aspect( aspect='equal',
adjustable='datalim' ). This is using the cvs version as of a few weeks ago.

Note: This uses a closed polygon as data. The type of shape which triggers the
bug is an asymmetical one (not symmetrical in x or y axes that is). Data which
is symmetrical in x and y axes does not trigger the bug.

If you have questions, please copy me on reply, as I get the digest.


import pylab

fig = pylab.figure( figsize = [ 8, 5 ] )
axes = fig.add_axes( [ 0.1, 0.1, 0.8, 0.8 ] )
axes.set_aspect( aspect='equal', adjustable='datalim' )

xs = [5.4, -6.3, -9.3, 0.5, 9.6, 5.4 ]
ys = [8.4, 7.7, -3.6, -9.9, -2.5, 8.4 ]

axes.plot( xs, ys )

pylab.savefig( 'figure.png' )
