PROBLEM TO BE SOLVED: To provide a bar graph monitor display device for displaying signals in different display forms on a single bar graph display unit while lightening the load on an external function by eliminating an increase in the load on the external function, such as a microprocessor, when display levels with different characteristics are displayed on the single bar graph display unit by switching or canceling restrictions on a display function itself. SOLUTION: The bar graph monitor display device comprises the microprocessor 11, comparators 13 (signal comparator) corresponding to the number of digits of the bar graph display unit, a reference voltage storage circuit 12 for storing and generating reference voltages for the respective comparators and setting a reference voltage of the microprocessor etc., and the bar graph display unit 13.
