Description
The code below illustrates the issue:
import matplotlib.pyplot as plt
from matplotlib.collections import EllipseCollection
fig, ax = plt.subplots( )
widths, heights, angles = 10, 10, 0
coords = [(10,10),(15,15)]
e = EllipseCollection( widths, heights, angles,
units='xy',
offsets=coords,
transOffset=ax.transData )
ax.add_collection( e )
ax.set_xlim( 0, 30 )
ax.set_ylim( 0, 30 )`Produces
as expected.
However, changing widths=10,10 produces the following.
Here the sizes are not transformed to the 'xy' units as expected.
The same thing happens when changing any of the other cyclable properties. eg: facecolor = 'rg'
The second case: widths=10,10 works as expected in 1.4.3, producing the first figure. I've tried to locate the issue in source, but I'm not familiar enough with the code to pinpoint exactly what is going wrong.
PS: I'm using the EllipseCollection as a base class to create a interactive tool for reducing astronomical image data here: https://github.com/apodemus/obstools/blob/master/ApertureCollections.py
