Abstract:

An efficient contour-plotting routine is discussed which is based on a scanning algorithm of Cottafava and LeMoli and employs bi-linear interpolation. An auto-interpolation scheme is developed which automatically adjusts the number of interpolations in any data square to produce smooth line segments. A program listing and examples are given.
