ABSTRACT:
In a graph generating device, when an input unit inputs data to be graphed, the data is stored in a data storage area through a processing control unit and a data generator. The data generator generates in a graph storage area element data for the graph elements based on the input data in the data storage area. A display control unit displays a graph on a display unit based on the data in the graph storage area. When the input unit directs the destination of a displayed graph element, coordinate data on the position of the destination is stored in a layout storage area through the processing control unit and a layout changing unit. The data generator 22 updates the element data in the graph storage area 43 based on the data in the data storage area 41 and the coordinate data in the layout storage area 42. The display control unit 24 updates and displays a graph on the display screen based on new element data in the graph storage area 43.
