set cterp

set cterp on|off

Turns spline smoothing on or off. "Sticks" until reset. Shaded contours are drawn without spline fitting, so to insure an exact match when overlaying contour lines and shaded contours of the same field, specify cterp as off. You can still use the csmooth option, which affects both contour lines and shaded contours.
