Necessary and sufficient conditions are derived for a cubic to be monotone on an interval. These conditions are used to develop an algorithm that constructs a visually pleasing monotone piecewise cubic interpolant to monotone data. Several examples are given that compare this algorithm with other interpolation methods. 5 figures.
