Select Categorized XYZ Plots from the Graphs - 3D XYZ Graphs menu to display the 3D Categorized Plots dialog. STATISTICA supports a variety of 3D graph types (i.e., Scatterplots, Surface Plots, Contour Plots/Area, Contour Plots/Line, Deviation Plots, Space Plots, Spectral Plots). Using categorized plots you can categorize 3D plots by the specified categories of a selected variable. One component graph is produced for each level of the grouping variable (or user-defined subset of data) and all the component graphs are arranged in one display to allow for comparisons between the subsets of data (categories).
