A register group that discards the oldest display data and always stores display data within a certain period of time in the past, and a trend display area is set near the area where the instantaneous values are displayed graphically to display data for a certain period of time in the past based on the data of the register group. A graph display device having a trend processing unit that processes display data within the display as a trend.
