Abstract
Depiction of graphics which are displayed in combination with function graphs is accelerated. Graphics to be displayed on a display device in combination with function graphs are selected and drawn according to the graphic information stored in the graphic information storage area of the data storage RAM memory. The selection is executed based on whether the rectangular region of interest is even partially within the region to be displayed on the screen. The selected graphics are written to the display RAM as bit images by a CPU which operates under the direction of programs set in the program ROM, and displayed on a display device. The data in the graphic information storage area is displayed on a display device upon pressing an EDIT MODE key, edited by operation with an EDIT key, DELETE key, character keys, etc., and the display device is switched to the graphic screen with the modified graphic thereon, upon repressing the EDIT MODE key.
