Thanks a lot for the update, I appreciate the patience you had to understand
what I wanted.

OK, I thought that might be the case. The behavior you want was not 
actually supported by scatter--at least it was contrary to the 
docstring--but it is reasonable, so I have made changes that I think 
will do what you want. I also changed the docstring to reflect this.
