棒グラフ表示装置。[Claims for Utility Model Registration] A cathode ray tube display device that displays image information as a pixel array determined by positions on the X-Y coordinates by main scanning in the X direction and sub-scanning in the Y direction perpendicular to the X direction. and a refresh memory for storing data to be displayed on the cathode ray tube display device in a memory element on an X-direction address and a Y-direction address corresponding to the position on the X, -Y coordinates of the pixel. A bar graph display device that displays an input signal as a bar graph image on a display screen includes an X-direction address counter that supplies an X-direction address to the refresh memory; ” signal, and a Y-direction matching circuit that outputs a Y-direction address to the refresh memory.
a direction address counter; a data zero point conversion circuit that subtracts an arbitrary number from the digital number representing the input signal; a data scale conversion circuit that scales the output value of the data zero point conversion circuit in an arbitrary ratio; a Y-direction matching circuit that outputs a logic "1" signal in a range where the output value of the direction address counter is less than or equal to the output value of the data scale conversion circuit; an output of the X-direction matching circuit; and an output of the Y-direction matching circuit. and a display requesting device for setting and changing a numerical value to be subtracted in the data zero point conversion circuit and a scale ratio in the data scale conversion circuit. A bar graph display device featuring:
