When the button in the legend is designated via the mouse 3, the position information is notified to the application program 7 via the system control unit 4. The application program 7 updates the display control table 6 so that the graph instructed by referring to the display control table 6 is in the non-display state if the graph is in the display state, and is in the display state in the non-display state. According to the change, the display state of the graph on the display device 1 is changed.

FIG. 2 is a diagram showing an example of a display screen of the display device 1 for displaying a graph. The display area 11 is an area for displaying a graph, and the display area 12 is an area for displaying a legend. The graph name 13 is a name for identifying each graph displayed in the display area 11. Button 14 is graph name 1
It is a button corresponding to 3 indicating whether or not each graph is being displayed.

FIG. 3 is a diagram showing an example of the data format of the display control table 6. The display control table 6 stores a flag indicating the display state 61 corresponding to each graph name 13 in the legend. "1" in the display state 61 indicates that the corresponding graph is displayed, and "0" indicates that the corresponding graph is not displayed. When the display control table 6 is initialized, it is arbitrary whether the display state of each graph is displayed or not displayed.
