We recently deprecated matplotlib.mlab.hist, and I am now hitting a
bug in numpy's historgram, which appears to be caused by the use of
"any" that does not exist in the namespace. Small patch attached.
The example below exposes the bug:
Python 2.4.2 (#1, Feb 23 2006, 12:48:31)
Type "copyright", "credits" or "license" for more information.
IPython 0.8.3.svn.r2876 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.
