3D Categorized Plots - Advanced Tab

Select the Advanced tab of the 3D Categorized Plots dialog to access the options described here.

Graph Type. Select the type of plot from the Graph Type list on this tab. Click the desired plot link below for a brief description of that type of graph.

Scatterplot	Surface
Space Plot	Contour/Lines
Spectral Plot	Contour/Areas
Deviation Plot

Variables. Click the Variables button to display the standard variable selection dialog, in which you can select the x-, y-, and z-axis variables as well as the grouping variable to be categorized for the graph. The selection you make will then be displayed in the area of the dialog below the Variables button. Note that the selected grouping variable does not have to be a categorical variable (e.g., contain codes); you can use one of the methods of categorization options in the Intervals group box to categorize a continuous variable. (The grouping variable is not necessary if the categories are defined via the Multiple subsets method.)

Intervals. Use the options in this group box to choose a method of categorization of the values in the selected grouping variable. Each of the methods is discussed in the Method of categorization topic.

Fit. You can fit one of several equations to the data or use one of the data smoothing procedures in the 3D categorized plot by selecting one of the predefined functions on this list. Note that if a fit option is not available for the selected graph type, the only available option in this list box will be Off.

Linear	Distance Weighted LS
Quadratic	Neg Expon Weighted LS

Deviation. 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.

No of Planes. This box is only available if you have selected Spectral Plot as the Graph Type. Use the No of Planes box to specify the number of spectral planes into which the data are segmented (compressed).

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