[matplotlib-devel] problem plotting log (works with 0.98.5.3)
Hello,
with 0.99.{0, 1rc1} I have problem with this code:
In [1]: import matplotlib.pyplot as plt
In [2]: import numpy as np
In [3]: x = np.arange(0., np.e, 0.01)
In [4]: y = np.log(x)
In [5]: print y[:2], y[-2:]
[ -Inf -4.60517019] [ 0.99325177 0.99694863]
In [6]: plt.plot(x, y);
In [7]: plt.show()
that generates the image attached, that's clearly wrong :)
I works fine with 0.98.5.3, so there's something in the 0.99.* that broke.
Regards,

Re: [matplotlib-devel] sampledoc: mark out prompts in ipython sessions?
Looks fine to me. We were offering to commit this to matplotlib, or should I?

You should let Fernando, so he can survive the annual purge of developers no longer committing :-) -- Come build with us!

Re: [matplotlib-devel] problem plotting log (works with 0.98.5.3)
Yes -- a bug was introduced where non-finite values were no longer being
ignored by the data extents finder. This has now been fixed on the
0.99.x branch (r7774) and the trunk.

Would it be easy to write a test (image based or non image based)? If so, would you mind doing it and checking it into the trunk? You can look at lib/matplotlib/tests/test_axes.py and lib/matplotlib/tests/test_basic.py for examples. Also, apologies about the buildbot master being down last night and this morning.

Good point. A test based on Sandro's example has been committed to SVN.

[matplotlib-devel] automatic label setting in Axes.add_* methods?
Hi,
add_line method sets label to something like "_line1" if not set.
def add_line(self, line):
if not line.get_label():
line.set_label('_line%d'%len(self.lines))
add_collection sets label to "collection1" if not set.
def add_collection(self, collection, autolim=True):
label = collection.get_label()
if not label:
collection.set_label('collection%d'%len(self.collections))
add_patch does nothing.
Can someone enlighten me why add_line and add_collection method sets the label?
Actually, my issue here is that collections without empty label show
up in the legend as "collection1" etc., instead of being ignored.
Regards,
-JJ
