PURPOSE:To display clearly a working locus by providing the titled graphic display system with a wire after-image display control part, a wire exclusive display control part and a switching part for selecting these display systems. CONSTITUTION:A display request signal from the external is supplied to a working locus display control part 101 and a wire display control part respectively. The display part 101 displays the moving loci of both ends of a wire and the control part 102 displays a segment indicating the wire. The control part 102 has a switching part 201 for selecting a display system, the wire after-image display control part 202 and the wire exclusive display control part 203. The display part 103 graphically displays data outputted from respective control parts 101, 102.
