Abstract:
A graph display control apparatus includes a figure display control unit, a graph figure change unit, a coordinate value calculation unit and a figure prominent display control unit. The figure display control unit sets a coordinate system to a display unit and displays (i) a first graph figure and (ii) a coordinate axis or a second graph figure in the system. The graph figure change unit moves or transforms the first graph figure in the system in response to a user operation to change the first graph figure. The coordinate value calculation unit detects an intersection point of (i) the changed first graph figure and (ii) the coordinate axis or the second graph figure and calculates a coordinate value of the intersection point. The figure prominent display control unit prominently displays the changed first graph figure when the coordinate value is an integer.
