Abstract
A graph arbitrarily input by the user is displayed on a dot-matrix display screen. When an instruction to determine any one of the characteristic points, such as intersections, local maxima, or local minima, is given, an characteristic point to be determined is calculated and the result is pointed by pointer P and, at the same time, the coordinates (X, Y) of the characteristic point are displayed. Depending on whether there is one other graph which overlaps or makes contact with the characteristic point of the graph and displayed dots of the graph near the characteristic point, it is determined whether a locus of the graph near the characteristic point is displayed unclearly. If the condition for unclear display has been satisfied, the graph including the characteristic point is enlarged repeatedly at the enlargement factor set by the user until the condition for unclear display is not fulfilled.
