Surface

The command set surface controls the display of surfaces by splot.

Syntax:

     set surface
     unset surface
     show surface

The surface is drawn with the style specified by with, or else the appropriate style, data or function.

unset surface will cause splot to not draw points or lines corresponding to any of the function or data file points. If you want to turn off the surface for an individual function or data file while leaving the others active, use the nosurface keyword in the splot command. Contours may still be drawn on the surface, depending on the set contour option. The combination unset surface; set contour base is useful for displaying contours on the grid base. See also set contour (p. [*]).
