<p>PURPOSE:To very easily attain the instruction of a graphic by displaying a graph on a graph display device and displaying simultaneously a symbol representing the graphic in applying various processings to the graphic. CONSTITUTION:When the graphic is displayed on a graphic display device and various processings are applied to the graphic, the symbol representing the graphic is displayed at the same time and the instruction to the graphic is applied by using the symbol. For example, a black dot 14 is a symbol to represent the apex of a rectangular parallelepiped 13 and a white circle 15 is a symbol representing the ridge of the rectangular parallelepiped 13. Thus, a designer 1 uses a stylus pen 6 so as to have only to designate the vicinity of a symbol representing the graphic displayed on a graphic display screen 12, thereby instructing a required graphic.</p> |
