3D Surface Plots - Quick Tab

Graphical Analytic Techniques

Select the Quick tab of the 3D Surface Plots dialog to specify the variables and fit of the 3D surface plot, as well as whether to include the raw data points in the 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 for the graph. The selection that you make will then be displayed in the area of the dialog below the Variables button.

Fit. You can fit one of several equations to the data or use one of the data smoothing procedures in the 3D surface plot by selecting one of the predefined functions on this tab.

Show Raw Data Points. Select this check box if you want the raw data points to be overlaid on the graph surface. (If the points are not located directly on the surface, then they will be "connected" to the surface by "spikes.")
