 1) if you have a contour, legend() wants to add all the contours to
 the list.  calling contour(...,label='_nolegend_') doesn't seem to
 help.

I think it would be quite unusual that someone would want contour lines 
to show up in a legend, so I made the change I suggested in an earlier 
response to this thread: the LineCollections in the ContourSet now have 
their labels set to _nolegend_.  If someone really does want contour 
lines in a legend, these labels still can be changed manually, as 
described earlier in this thread.

 the list.  calling contour(...,label='_nolegend_') doesn't seem to

You should be able to set the _nolegend_ label property on the
contour set line collections like so:

   cs = contour(...blah...)

   for coll in cs.collections:
coll.set_label('_nolegend_')

of use setp for the same purpose.

   setp(cs.collections, label='_nolegend_')

contour doesn't use the kwargs to set the line collection properties,
which is why it is not working in the contour commands.  some plot
commands use the kwargs to update the artist properties that the plot
command creates, some do not, and the only way to know is the read the
individual docstrings of the commands.

Let me know if this works because it is untested.

Maybe I should make _nolegend_ the default for contour and contourf 
collections?

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'.

Call setp on the returned object:

In [8]:y = plot(sin(arange(10)))

In [9]:setp(y)
  alpha: float
  animated: [True | False]
  antialiased or aa: [True | False]
  axes: unknown
...
  xdata: array
  ydata: array
  zorder: any number

And similarly:

In [11]:z = contour(outerproduct(arange(10), arange(10)))

In [12]:setp(z)
  alpha: unknown
  array: unknown
  clim: a length 2 sequence of floats
  cmap: a colormap
  colorbar: unknown
  label_props: unknown
  norm: unknown

Or, in ipython you can type z.set_TAB to see the completions. With
the list returned from plot you cannot simply type y[0].set_TAB but
have to assign the value of y[0] to a variable first.
