PROBLEM TO BE SOLVED: To freely designate the range of the graph to be displayed. SOLUTION: A memory part 3 stores the function expression data. A range key 1E designates an optional range of the graph that is shown in the function expression data stored in the part 3. An arithmetic part 5 calculates a graph corresponding to the range designated by the key 1E based on the function expression data stored in the part 3 and also calculates a coordinate axis corresponding to the range designated by the key 1E. A control part 2 sets the graduations to the coordinate axis calculated at the part 5 and performs its control to display the coordinate having the graduations and the graph calculated at the part 5. |
