## Abstract

An information displaying system is configured to display a time axis region and a signal display region on a display device. The time axis region is configured to display a time axis of a biosignal along a first direction and to display a first mark on the time axis, and signal display region is configured to display a plurality of waveforms of the biosignal side by side in a second direction which is different from the first direction. In response to receiving a designation information designating a time, the information displaying system displays, on the signal display region, the plurality of waveforms for a predetermined time range including the time designated by the designation information, and displays a line extending in the second direction at a location of the waveforms corresponding to the first mark.
