Hi,
I updated to the latest svn version of matplotlib this morning, and
Axes.scatter seems to be broken when using marker='v', '>', '<', or '^':
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as mpl
fig = mpl.figure()
ax = fig.add_subplot(1,1,1)
ax.scatter([1,2,3], [4,5,6], marker='v')
fig.savefig('test.png')
gives:
Traceback (most recent call last):
File "test.py", line 7, in <module>
ax.scatter([1,2,3], [4,5,6], marker='^')
File "/Users/tom/Library/Python/2.6/site-packages/matplotlib/axes.py", line
5764, in scatter
transOffset = self.transData,
File "/Users/tom/Library/Python/2.6/site-packages/matplotlib/collections.py",
line 695, in __init__
self._paths = [self._path_generator(numsides)]
File "/Users/tom/Library/Python/2.6/site-packages/matplotlib/path.py", line
415, in unit_regular_polygon
path = cls(verts, codes)
File "/Users/tom/Library/Python/2.6/site-packages/matplotlib/path.py", line
117, in __init__
assert len(codes) == len(vertices)
AssertionError
This did not occur when I updated to the latest svn a couple of days ago, so it
must be due to a pretty recent change.
Cheers,
Tom
