<p>PURPOSE:To reduce the memory capacity and to improve the general usefulness of a system by updating the time of preceding measurement data to the time of current measurement data and arbitrarily combining and displaying stored measurement data in the case of coincidence between current measurement data and preceding that. CONSTITUTION:A measurement data gathering part 1 compares inputted measurement data and second gathered information with each other, and the gathering time of second gathered information is updated to the time of latest measurement data if second gathered information is equal to the gathered value of measurement data, and hereafter, the processing is performed by these procedures at each time of input of measurement data. A display data control part 5 calculates an approximate value by gathered information of time series data with a measurement point as the unit in a time series data memory 3 and sets he time base resolution of the axis of abscissas to an arbitrary value like intervals of 5 minutes to plot the approximate value and displays it on a display device 7. Thus, the memory capacity is reduced, and the general usefulness of the system is improved because the time base resolution is freely set.</p> |
