Logic for Viewing 2D Data in 3D

 Logic for Viewing 2D Data in 3D
Do with groupings of a unit (grouping function g) as x axis and observee in y axis. (Note: the fourth dimension would be grouping of groupings, i.e. higher order grouping functions as possible inputs.) Cell(x,y) equals the function of data items h(f(),g(),v,t(y,z,w) where y=y1) -- in our case, given y1 and grouping function g, lookup z for record that matches f(g(w)) -- below, for y1=observee1, 1.1 and 1.2 could be grouped into group with key v=1, i.e. g(v,t)={1.1,1.2}, then f(g(v,t))= max of {1.1,1.2} or 1.2, so return value is b == cell(x,y)

sample data:
(y)                (z)   (w)
observee1     a     1.1
observee1     b     1.2
observee1     c     2.1
observee2     a     2.1
observee2     a     1.1
