3D Scatterplots - Advanced Tab

Graphical Analytic Techniques

Select the Advanced tab of the 3D Scatterplots dialog to select from a variety of graph types. Here, you can specify the deviation level, the number of panes in spectral plot, and whether to use multiple subsets of the data.

Variables. Click the Variables button to display the standard variable selection dialog, in which you can select the x-, y-, and one or more z-axis variables for the graph. The selection that you make will then be displayed in the area of the dialog below the Variables button.

Graph Type. Select the type of 3D scatterplot to be plotted from the Graph Type list. Click the desired plot link below for a brief description of that type of graph.

Statistics. You can include the multiple correlation in the footnote of the graph by selecting the Multiple r(z/xy) check box.

Deviation Level. Use this box (applicable to Deviation and Space plots) to specify a value on the z-axis that determines the level from which deviations are derived; or in the case of Space Plots, this value determines the Z-level of the X-Y plane.

Number of Planes. Use this box (applicable to Spectral plots) to specify the number of spectral planes into which the data are segmented (compressed).

Mark Selected Subsets. When you click this button, the Specify Multiple Subsets dialog will be displayed, in which you can specify selection conditions that will subset (i.e., categorize) the cases in one plot. For more information, see Mark Selected Subsets.
