Hi,
I have been trying to use the Affine2D transformation with pcolor and contour,
with no success. The following script and comments illustrates my problems:
matplotlib.use('Agg')
import matplotlib.pyplot as mpl
from matplotlib.transforms import Affine2D
import numpy as np
image = np.random.random((100,100))
fig = mpl.figure()
ax = fig.add_subplot(1,1,1)
ax.pcolor(image, transform=Affine2D()) # Does not work - the image is not there!
fig.savefig('test1.png')
fig = mpl.figure()
ax = fig.add_subplot(1,1,1)
ax.contour(image, transform=Affine2D()) # Ok, but transformation wouldn't
change anything anyway
fig.savefig('test2.png')
fig = mpl.figure()
ax = fig.add_subplot(1,1,1)
ax.contour(image, transform=Affine2D().scale(10.,10.)) # Does not work - the
image is unchanged
fig.savefig('test3.png')
Is there a reason why transform doesn't work for contour and pcolor?
Thanks for any help,
Thomas
