GRAPH VALUE DISPLAY PROGRAM, GRAPH VALUE DISPLAY METHOD AND RECODING MEDIUM

PROBLEM TO BE SOLVED: To provide a graph value display program, a graph value display method and a recording medium for displaying the value of the graph enabling easy and accurate reading of an optional point on the graph as a numerical value by generating and overlappingly displaying a virtual graph with an optional scale based on a graph of a datasheet, etc., to display the numerical value in lateral and longitudinal direction when a cursor is positioned on an optional position or the cursor is on the graph. SOLUTION: The graph value display program makes a computer carry out a step to read in and display a graph, a step to generate a virtual graph with a start point, an end point and a scale corresponding to and based on specification or input of the start point, end point and scale on the displayed graph, a step to overlappingly display the generated virtual graph on the graph, a step to display a coordinate of a cursor when the cursor is moved or specified on the overlappingly displayed virtual graph.
