Abstract: PURPOSE:To eliminate the need of a special mechanism for loading in advance marker shape data by holding shape data of a marker as a subroutine program operated as a part of a graphic plotting means, and changing a shape of the marker by substitution of the subroutine program. CONSTITUTION:At the time of plotting a graphic, when an application program 8 instructs plotting of a marker to a graphic plotting means 9, a marker identification number is given. When plotting of the marker is instructed, the graphic plotting means 9 calls a marker display means 10. Subsequently, the marker display means 10 gives the marker identification number given from the application program 8 as an argument and calls a marker expansion processing program 7, obtains marker shape data corresponding to the given marker identification number, and sends its data as a segment group to a graphic display device 11. Accordingly, the marker is displayed on the graphic display device 11. In such a way, a special mechanism for loading marker shape data becomes unnecessary.
