DISPLAY PROGRAM BY GROUP MOVEMENT OF GRAPH

摘要

Provided is a technology for accurately analyzing a measurement value using a first graph line representing the measurement value and a second graph line representing a control signal. The first and second graph lines specified by the same file name are associated with each other, and when a desired graph line is selected from the first graph lines (134a, 134c, 134d) of the measurement values displayed on a screen (100) and the second graph lines (144a, 144c, 144d), and the selected graph line is determined as a movement target, the associated first and second graph lines are moved together. Accordingly, the relationship between the first graph line for the measurement value and the second graph line representing the timing chart can be maintained after the movement, and thus, an analysis error does not occur.
