Zusammenfassung:PROBLEM TO BE SOLVED: To extract a portion of measurement values, and to easily compare graphed and extracted measurement values. SOLUTION: A lot of measurement values are read and displayed as a primary graph on a screen 100. Measurement values to be compared are extracted by specifying a start point. The extracted measurement values are displayed in secondary graphs 134a and 134b. When the secondary graphs 134a and 134b are not overlapped, the amount of shift between the graphs 134a and 134b is measured by first and second measurement lines 101 and 102, and one of the shifted secondary graphs 134a and 134b is moved to be superimposed on the other one.
