PROBLEM TO BE SOLVED: To display a graph expressing inputted data without previously specifying the sort of a regression graph. SOLUTION: When numeral data for plotting a graph are inputted by the operation of various keys in a key input part 12, a CPU 11 discriminates the number of inputted numerical data, calculates a functional expression of a degree corresponding to the number of numerical data and displays a graph on a display part 16 based on the calculated functional expression. Since the functional expression corresponding to the inputted data can be calculated without previously inputting specification for the degree of the functional expression, a graph suitably approximating plural inputted numerical data can easily be displayed. |
