Re: [Matplotlib-users] Omitting curves from a legend

[Bill B. <wb...@gm...>]

Ok.   Thanks.  I'll give the setp on the ContourSet thing a try.

Documentation issue/question:  I figured there was probably some way
to set attributes individually using the return value from contour
since contour's docstring helpfully tells me that countour returns a
ContourSet object.  However,  'ContourSet?' in ipython gives me
nothing.  Similarly with plot(), it says it returns a 'list of lines'
but that is not so useful since I can't look up the docstring for
'list of lines'.
