Exploring Data in Three Dimensions
SAS/INSIGHT software provides rotating plots, surface plots, and contour plots
for exploring data in three dimensions.
A rotating plot is a three-dimensional scatter plot,
so it shows a graphic representation
of the relationship among three interval variables.
A surface plot is a rotating plot with a surface that
models a third variable as a function of two other variables.
A contour plot shows how the values of one variable
may depend on the values of two other variables.
