PROBLEM TO BE SOLVED: To provide a graph display control device effective for learning of relation between a condition uniquely specifying a graphic formula, the graphic formula, and a graph. SOLUTION: When a "coordinate on a graph" is input as a graph condition first (a), a message Msg, which prompts to input other lacking (necessary for establishing a graph decision condition) graph condition, is displayed (b) because the graph decision condition uniquely specifying the graph is not established at this moment. If a "gradient" is input as a next graph condition, the graph decision condition is established, and a graph G1 of the graphic formula, which meets these graph conditions of the "coordinate on a graph" and the "gradient", is drawn (d).
