I'm interested in this, too.  Is there currently a document similar to 
http://www.mathworks.com/access/helpdesk/help/techdoc/creating_plots/hg_objec.html 
or http://www.mathworks.com/access/helpdesk/help/techdoc/ref/func_b52.html 
that defines what what handle types, properties of those types, 
and allowable child types should exist for each figure?  If not, I would 
be willing to start working on one or help develop what is already there.
