contour question

Hello,

I'm using a svn version of matplotlib and the API changed for contour. I want
to have the coordinate of the contour. Before Eric Firing (I think) gave a
solution to do it:

val = contour(xRange,yRange,delchi2,[1])
t = asarray(val.collections[0].get_verts())

but now get_verts doesn't exist anymore.

I tried to do:

cs = contour(a)
path = cs.collections[0].get_paths()

but I don't know how to use it. Basically I think that I have the contour
coordinate but I don't know how to recuperate them. I need it to export them
in a data file so it's the reason I want to recuperate them.

Thank you for any help

N.

ps: It's a little bit difficult to access to the help for a method now some,
perhaps most, of them are missing a docstring. So it's difficult to
understand what it is the meaning of each of them.

example:

col.get_paths?
Type: instancemethod
Base Class: <type 'instancemethod'>
String Form: <bound method LineCollection.get_paths of
<matplotlib.collections.LineCollection object at 0x9038a4c>>
Namespace: Interactive
File: /usr/lib/python2.5/site-packages/matplotlib/collections.py
Definition: col.get_paths(self)
Docstring:
    <no docstring>

.get_paths() returns a list of Path objects. (See path.py). For each Path object, you can get an Nx2 array of vertices from its "vertices" member. You can also use the "iter_segments" method to iterate through each of its vertices, but that's primarily only useful when there may be bezier curves in the path, which there won't be in the case of contours.

Missing docstrings is definitely a problem that will need to be worked on.

Cheers,
Mike
