Displaying Surface Views

The Surface Window File > Options command controls surface display, Figure 136 (A different dialog box controls Graph View.)

 

Figure 136: Surface Options Dialog Box

Options:

Surface

Displays the array’s data as a three-dimensional surface; otherwise, displays the surface as a grid.

XY

Reorients the view’s XY axes. The Z axis is perpendicular to the display.

Auto Reduce

Derives the displayed surface by averaging neighboring elements in the original dataset, in order to speed visualization by reducing surface resolution. Clear this option to accurately visualize all dataset elements.

This option supports either viewing all your data points — which takes longer to appear in the display — or viewing the data average over a number of nearby points.

Figure 137 shows different views of the same data, based on Surface and XY options.
