ABSTRACT:
There are provided an electronic computing apparatus having a graph displaying function and a graph displaying method which allow an optimum graph to be quickly displayed. A graph is displayed on a display based on data for displaying the graph inputted from a key input section or the like. When one numeric key selected from among a plurality of numeric keys is specified by a predetermined number of times, a quadrant corresponding to the numeric key is selected from a quadrant selection table and a scale corresponding to the specified number of times is selected from a quadrant scale selection table, redisplaying a part of the graph existing in the selected quadrant on the selected scale. Thus, a desired graph may be quickly displayed by selecting the quadrant and scale of the displayed graph.
