Abstract
A graphic display control device easily changes a display of a graph or graphic by operating an area where a graph or graphic is generally displayed. When a CPU detects trace execution inputting, the CPU displays a trace pointer on a graph, and simultaneously displays coordinates at which the trace pointer is positioned. Further, when the CPU detects an operation of a graph controller by an input pen, the CPU adds a predetermined value to an x-coordinate value of the trace pointer to perform tracing of the graph.
