Thanks for the information on the Wilkenson book, the Grammar of Graphics.  I
will order a copy. I think the average SPSS graph user will be in for a
major shock, if I understand his paper correctly on his web site. Instead of
treating a graphics display as a viewer for underlying data, GPL treats data as
an accessory to viewing a graph. GPL is based on the mathematical definition of
 the graph of a function and uses that definition to organize data linked to
the  graph. Ralph
