PROBLEM TO BE SOLVED: To express a given functional formula as the combined body of the plural functional formulas by easily dissolving it without requiring a complicated and troublesome input operation in a graph display device. SOLUTION: When a 'division' key 12c is operated in a state where the optional function formula 'Y1' is inputted and displayed in a liquid crystal display part 13, configuration elements '2x2', '+3x' and '+1' in the functional formula are divided in accordance with an operator in the formula and stored in a division data memory 19c and the division patterns are displayed by identification. When the desired division pattern is selectively displayed and an 'OK' key 12d is operated by the operation of key 12h or 12i or the direct pen touch operation with a tablet 14 as against each configuration element in the functional formula, the dissolved functional formulas 'Y2' and 'Y3' are generated in accordance with the above operation, stored in a functional formula data memory 19d in accordance with individually different display designation color, classified by color together with the functional formula 'Y1' of a division source and displayed by graphic plotting. |
