PROBLEM TO BE SOLVED: To improve operability when moving a value display area in a waveform display device.SOLUTION: A waveform display device displays a waveform display area where waveforms are displayed along a time axis and a value display area where values at specified points of waveforms on the time axis are displayed, on a display screen. The waveform display device comprises: an operation processing part for obtaining a coordinate specified by a user operation on the display screen; and a display control part for changing a display position in the value display area on the basis of the specified movement position in a case when the specified start coordinate is within the value display area being displayed, and for further changing a form of the waveform display area according to a change of a display position of the value display area. |
