A 3D surface plot displays a three-dimensional relationship in two dimensions, with predictor variables on the x- and y-scales, and the response (z) variable represented by a surface or a wireframe.
To edit the surface on a graph, double-click the surface. You can edit the following.
Specify the surface type
On the Attributes tab, select one of the following:
Edit the surface pattern
On the Attributes tab, you can specify the surface color for a 3D surface plot, or the surface color, wire color, and wire size for a wireframe plot.
Edit the lights on the surface
The surface is illuminated by lights in different positions around the graph so that you can highlight surface features. To change the brightness of the surface, and the number and position of up to three surface lights, double-click the surface.
Change the position of the surface lights by entering coordinates
On the Lights tab, select Custom. Under Relative Position, enter the coordinates and color for up to three lights. The x-, y-, and z- coordinates for the positions of lights on a 3D surface plot are expressed relative to the center of the data region, which is coordinate 0, 0, 0. Coordinate units are designed to be consistent between x, y, and z. Thus, they are not related to the data measurement units.
You can also use the 3D Graph Tools toolbar to rotate the lights on a 3D surface plot.
Change the surface brightness
On the Lights tab, in Brightness enter a number between 0 (darkest) and 100 (brightest).
