matplotlib-devel Mailing List for matplotlib

This is fixed now in SVN.  The problem was that Numeric arrays lack a 
"len" attribute, and "hasattr(xmin, 'len')" was being used to find out 
whether xmin is a scalar or a length-2 array (xmin, xmax).  The solution 
is to do the test with "iterable(xmin)" instead.  The bug was introduced 
in 2782.
