Eric -
I just installed version 0.90 on my windows machine and it seems that
axis('scaled') doesn't work properly yet.
I thought axis('scaled') will change the axes such that the aspect ratio is
equal WITHOUT changing the limits on the axes.
A simple example shows that this goes wrong (I thought this used to work):
from pylab import *
plot([1,2,3],[1,2,1])
axis([1,2,1,2]) # define new axis limits
axis('scaled')
And now Python comes back with (1.0, 3.0, 0.80000000000000004, 2.0), which
are the limits of the original plot command obtained using autoscale_view.
I think this is an easy fix in the axis function of axes.py.
Here you do an autoscale_view, which shouldn't be done in the 'scaled'
option.
I think you only need to change the indicated line below.
Thanks,
Mark
def axis(self, *v, **kwargs):
'''
Convenience method for manipulating the x and y view limits
and the aspect ratio of the plot.
kwargs are passed on to set_xlim and set_ylim -- see their
docstrings for details
'''
if len(v)==1 and is_string_like(v[0]):
s = v[0].lower()
if s=='on': self.set_axis_on()
elif s=='off': self.set_axis_off()
elif s in ('equal', 'tight', 'scaled', 'normal', 'auto',
'image'):
self.set_autoscale_on(True)
self.set_aspect('auto')
if s!= 'scaled': self.autoscale_view() # THIS LINE WAS
CHANGED BY ADDING THE IF STATEMENT
self.apply_aspect()
if s=='equal':
self.set_aspect('equal', adjustable='datalim')
elif s == 'scaled':
self.set_aspect('equal', adjustable='box', anchor='C')
self.set_autoscale_on(False) # Req. by Mark Bakker
elif s=='tight':
self.autoscale_view(tight=True)
self.set_autoscale_on(False)
elif s == 'image':
self.autoscale_view(tight=True)
self.set_autoscale_on(False)
self.set_aspect('equal', adjustable='box', anchor='C')
