matplotlib-users Mailing List for matplotlib

Hi,
Congratulations on the new release.
I just tried installing in a fresh installation of Python 2.7 from Python.org
Am I right in thinking the recommended method is:
 pip install matplotlib
? I did this, and then:
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/pyplot.py",
line 24, in <module>
 import matplotlib.colorbar

 import matplotlib.collections as collections

 import matplotlib.backend_bases as backend_bases

 import matplotlib._png as _png
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/_png.so,
2): Library not loaded: /usr/X11/lib/libpng12.0.dylib
 Referenced from:
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/_png.so
 Reason: Incompatible library version: _png.so requires version
42.0.0 or later, but libpng12.0.dylib provides version 36.0.0
There were no previous versions of matplotlib installed. This on OSX 10.6:
Python 2.7.5 just installed from python.org
X11 installed from the Apple installation disks for 10.6 before `pip
install matplotlib`
No homebrew etc
Any hints about how I should debug this further?
Thanks a lot for any help,
Matthew

could you use the bbox_to_anchor keyword to place your legend in a precise
way so that they could be alignd?
sorry ,this is the only way I could think of (But I am not a real expert in
matplotlib)

Hi Frédéric,
I don't understand what is the "dictionnary of figures" feature you are
mentionning. Maybe you could write a short mockup script using it ?
However, it's worth mentionning that you can use not only numbers in
figures but also *strings*.
>>> fig = plt.figure('crude oil price')
I use this 95 % of the time. I think it helps a lot the figure
addressing problem.
best,
Pierre

<div>this is my first eMail to a mailing list, I hope I&#39;m not messing it up. I posted my question already on stackoverflow, but apparently there&#39;s no simple solution to it:</div>

<div>In other words, I have a Figure with a many-entries-legend, but the legend text for most but not all of the object is very short. I&#39;d like to use two or more columns for those short entries and switch back to single column mode when dealing with the longer legend entries.</div>
<div>&nbsp;</div>
<div>Two options came to my mind. One, make the legend work like a multicolumn-table in LaTeX or, two, having a container with multiple, well-aligned legends with individual properties for each one.</div>
