A waveform display apparatus displays a waveform on a display device. A scale plate is provided with graduations corresponding to values of the waveform. The scale plate is displayed in a region where the waveform is displayed, on the display device, in a state that a time axis is movable. A value of the waveform at an intersection point between one side of the scale plate and the waveform is displayed on the display device. |
