PROBLEM TO BE SOLVED: To sequentially display a corresponding figure and graph while variable values of plural variables contained in a formula for segment plotting on a coordinate are separately changed to arbitrary values in a graph display device for plotting and displaying the figure and the graph, which correspond to inputted graphic plotting data and function formula data. SOLUTION: The two variable (s) and (t) contained in an arbitrary coordinate change formula of respective apex coordinates A, B and C for dynamically displaying figure data are separately changed to the arbitrary values with the operation of '↑' '↓' or '←' '→' cursor keys 12g-12j in variable value display bars B1 and B2, and they are changed into figure data corresponding to the coordinate change formula for which the corresponding variable values are substituted so as to dynamically display them. |
