An information displaying system according to an embodiment of the present disclosure includes a first display section configured to display a time axis of detected signals along a first direction, a second display section configured to display a plurality of signal waveforms based on the detected signals in parallel so that the signal waveforms are arranged side by side in a second direction different from the first direction, and a controller configured to control the first display section and the second display section. When, in the second display section, a location on at least one of the plurality of the signal waveforms or near the at least one of the plurality of the signal waveforms is designated, the controller highlights the designated location, and displays a designated result on a time location in the first display section corresponding to the designated location.
