PURPOSE:To continuously display actual graph data and predictive graph data on a same graph while distinguishing clearly from each other, by outputting a predetermined graph part to a display device as graphic data having a form different from an actual graph part by means of a graph data converting means. CONSTITUTION:When numerals to be used for forming a graph are inputted from an input device 11, a CPU 12 converts the numeral data into graph drawing data by using a graph data converting means and displays the graph drawing data on a display device 14. After input of form data and numeral data is completed, numeral data in a graph data storing memory 13 can be designated to data 311 for forming the graph, data 312 for forming a predetermined graph, and data 313 which are not used for forming the graph in accordance with instructions from the input device 11. Then it is discriminated whether or not the data 312 for forming a predetermined graph are used and, if the data 312 are used, partial designation which divides display data 32 into actual display data 321 and display data 322 of a predetermined graph is performed. Thereafter, graph formation is instructed and the graph is displayed. |
