Abstract

For the purpose of realizing a display method for a portable electronic measuring device that allows the user to know his condition more easily and in greater detail by making it easy for him to read the display of measured results even if the display device is limited in size due to its portability, a bar graph is displayed in dot display area (134) of liquid crystal display device (13) of the portable pulse measuring device which extends up at each time interval according to the absolute value of the pulse rate after the measurement of time is started and until the pulse rate reaches a prescribed range, and after the pulse rate reaches the prescribed range, a bar graph is displayed that extends in the positive direction or the negative direction at each time interval according to the difference from the prescribed reference pulse rate. When temporal changes in the pitch during running are displayed in dot display area (134), they are displayed in a segmented graph.
