摘要： It is an object of the invention to solve problems with a calculator capable of displaying a graph of a function in that the characteristics of a graph displayed by inputting a function can not be recognized when a desired display range is not at an appropriate value and in that a value to change the display range has had to be input on a trial and error basis, which has made the operation very complicated. A calculator according to the invention displays a graph of a function on a reduced scale, further displays buttons for increasing and decreasing display ranges of an X-axis and a Y-axis around the graph and changes the graph of the function and displays it again in response to instructions by the user on the buttons. This makes it possible to correct the display ranges of the graph of the function easily.

摘要： 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.
摘要翻译：提供一种具有图形显示功能的电子计算装置和允许快速显示最佳图形的图形显示方法。基于用于显示从键输入部等输入的图形的数据，在显示器上显示图形。当从多个数字键中选择一个数字键指定预定次数时，从象限选择表中选择与数字键对应的象限，并且从象限中选择与指定次数相对应的标度缩放选择表，重新显示所选择的象限中所存在的图形中的一部分。因此，可以通过选择所显示的图形的象限和比例来快速显示期望的图形。
