<p>PROBLEM TO BE SOLVED: To improve the work efficiency of plant monitoring by calculating a display interval between valid data based on the discriminated result of whether each data value of a TY graph is valid or not and discriminating whether or not the interval between the valid data is to be plotted with a line based on the calculated display interval. SOLUTION: TY graph data retrieved from a recorded operation history data file and edited for TY graph display are stored in a TY data file 11. A quality discriminating means 13 discriminates the quality of respective data values displayed on the TY graph and a line plotting discriminating means 15 plots the interval between the start and end points of a data omission term with the line corresponding to the data omission term based on the quality discriminated result. An output processing means 19 outputs the TY graph data from the line plotting discriminating means 15 to a display device 17 such as CRT or LCD and a printer or the like as needed.</p> |
