3D Scatterplots
3D scatterplots visualize a relationship between three
or more variables, representing the X, Y, and one or more Z (vertical)
coordinates of each point in three-dimensional space.
You can select one of several types of graphs: Scatterplot, Space
Plot, Spectral Plot, Deviation Plot, or Trace
Plot. Use Scatterplots to
visualize the relationship between three (or more) variables using X,
Y, and Z coordinates in a three-dimensional representation with the x-,
y-, and z-axes at the edges of a cube.

Space Plots move
the z-axis to the center of the plot and allow the x-y plane to be placed
at a specified point on the z-axis. Use Spectral
Plots to explore relationships among three variables by compressing
the data into a specified number of planes. Values of variables X and
Z are interpreted as the x- and z-axis coordinates of each point respectively;
values of variable Y are clustered into equally spaced values corresponding
to the locations of the consecutive spectral planes. In Deviation
Plots, data points are represented in 3D space as �deviations�
from a specified base level of the z-axis. In Trace
Plots, individual data points are connected with a line (in the
order in which they were read from the datafile), visualizing a �trace�
of sequential values.
