A method, called “isometric line mapping(ILMAP)”, is described for plotting contours of h which is a function of χ and y. An h value at each grid point on the χ-y plane is estimated according to the weights based on the distances to all measured points. Furthermore, the h values are smoothed by means of the moving average method. Two applications to psychological data(Ichikawa, 1981; Carroll, 1972)are presented to show that ILMAP is useful for visually grasping the effects of χ and y upon h.
