。 In a graph display device that inputs process quantities, outputs appropriate manipulated quantities using set values, and displays these quantities or values as instantaneous values on a graph on the display, a a maximum value register; a maximum value detecting means that is reset by a reset signal and compares the previous instantaneous value with the value in the maximum value register every control cycle and stores the larger value in the maximum value register; a minimum value register for storing a value; and a minimum value detection means that is reset by a reset signal and compares the previous instantaneous value and the value in the minimum value register every control cycle and stores the smaller value in the minimum value register. ,
and horizontal bar graph display means for displaying the highest value and the lowest value as a horizontal bar graph.
