There appears to be a problem with Agg -- not sure about PS yet. We
recently added support for "true ellipses" using arcs rather than
polygons, and it appears we have messed something up. Charlie, take a
look at this case -- depending on the y-zoom the x extent of the
ellipse is different:
from pylab import figure, show
from matplotlib.patches import Ellipse
xy = 0.38,0.52
props = dict(xy=xy, width=1e-1, height=3e-1,
facecolor='red',
angle=30.0, linewidth=2, fill=True, alpha=0.5)
e1 = Ellipse(**props)
e2 = Ellipse(**props)
fig = figure()
ax1 = fig.add_subplot(211)
ax1.add_artist(e1)
ax1.set_xlim(-.1, .7)
ax1.set_ylim(0.35, .7)
ax2 = fig.add_subplot(212, sharex=ax1)
ax2.add_artist(e2)
ax2.set_ylim(0.4, .6)
show()
Any ideas?
