PURPOSE:To display time series change of a measuring signal for a long time without reducing resolution by dividing and setting up a time axis of a display screen of a CRT display device into two parts or more having different resolution. CONSTITUTION:A device consisting of an electronic computer 2, a storage device 3 and a CRT display 4 is constituted so that a characteristic curve 7 indicating the time change of a measuring signal is obtained at fine resolution in the time axis 5 having fine resolution and a characteristic curve 9 indicating the time change of measuring signal is obtained at rough resolution in the time axis 8 having rough resolution. Consequently, time series change can be simultaneously measured by fine and rough resolution during the period from the current time to time T0 and before T0, respectively. |
