PURPOSE:To implement a plot command sequence at high speed by previously converting same geometric graphics to a plot command based on a relative co-ordinate and connecting a movement command which shows the destination with the geometric plot command. CONSTITUTION:A graphic data memory part 10 stores the shape information on each symbol such as a circuit diagram which should be drawn and the positional information in the circuit diagram of each symbol. A shape plot command memory part 20 stores the shape of each symbol in the plot command format based on the relative co-ordinate. A plot command string memory part 30 stores not only the content of the shape plot command memory part 20 but also the movement command which moves each proper symbol according to the positional information on each symbol stored in a graphic data memory part 10.
