PROBLEM TO BE SOLVED: To provide a display device capable of comparing a dynamic graph and other graphics with each other by displaying them at the same time when the dynamic graph is displayed. SOLUTION: Data for a functional equation of a dynamic graph are inputted by depressing a register/data input key 17 of an input part. A display turns into scale data input display by pressing an EXE key 12. Desired values are inputted in order of start, end, and pitch as a variable of the functional equation for the dynamic graph, and the ranges of the variables for the data are set. Such a functional equation and a scale are made stored in a dynamic graph system register 21 and start register 23, an end register 24, and a pitch register 25. A functional equation for background data is inputted to a background system register 22. CPU 7 performs arithmetic operation based on the functional equation of the dynamic graph and that of the background graph, and a display driving circuit 3 is driven to plot the dynamic graph and the background graph on a display part 2. |
