Hi all,

I'm taking a look at the plotting docs right now.

One of the scripts in the callback documentation currently fails with a NotImplementedError.  

The somewhat scipt is here: http://paste.yt-project.org/show/4857/

And the traceback is here: http://paste.yt-project.org/show/4858/

I'm not sure whether anyone has looked in detail at the clump finder in 3.0.  Does anyone know about its status?  I'm not even sure if this is an issue with the clump finder per se.
