Object points. A plot of the object points is displayed.
Objects and variables (biplot). The object points are plotted with your choice of the variable
coordinates—component loadings or variable centroids.
Objects, loadings, and centroids (triplot). The object points are plotted with the centroids
of multiple nominal-scaling-level variables and the component loadings of other
variables.
Biplot and Triplot Variables. You can choose to use all variables for the biplots and
triplots, or select a subset.
Label Objects. You can choose to have objects labeled with the categories of selected
variables (you may choose category indicator values or value labels in the Options dialog
box) or with their case numbers. One plot is produced per variable, if Variable is selected.
Categorical Principal Components Loading Plots
The Loading Plots dialog box allows you to specify the variables which will be included
in the plot, and whether or not to include centroids in the plot.
