PURPOSE:To improve the plotting speed by executing the plotting processing by using repeatedly a graphic plotting command train subjected to editing processing, in the case of plotting repeatedly a regular shape graphic of the same shape. CONSTITUTION:This device is provided with an editing processing part 11 for executing the editing processing to a graphic plotting command train generated by a graphic plotting command generating part 2, and a graphic plotting command train storage part 14 for storing the graphic plotting command train. In such a state, with respect to the graphic plotting command train generated by the graphic plotting command generating part 2, the command editing processing for eliminating a redundant part of the graphic plotting command train and changing the execution sequence is executed by the editing processing part 11, and by using the edited graphic plotting command train, a regular shape graphic is plotted to a screen of a display device D by a plotting processing part 7. In such a way, by merely defining only shape information, the regular shape graphic can be defined, and corrected and changed easily, and the time when information is interpreted whenever a plotting request of the same regular shape graphic is generated is eliminated, and the graphic plotting can be executed at a high speed. |
