Rene,

	Thanks for your usual promptness in responding.

	That definitely worked.  However, when doing many cuts
on a 2D histogram, this process can get time intensive.

	I wonder how feasible it would to set the default
of tree.Draw to be a 2-D histogram as opposed to a scatter
plot?

	Thanks.

	regards,

	Lars
