Zusammenfassung:PROBLEM TO BE SOLVED: To provide a data display apparatus that can efficiently search through long term plant data and display a graph allowing trend monitoring and outlier monitoring. SOLUTION: Plant data is captured into a plant data table 3 at predetermined data capture periods, the data is then captured at data compilation periods longer than the data capture periods and saved to a plant data history information table 7 by each data compilation period, and long term search history information including maximum, minimum and mean values is created and saved to a long term search history information table 11 about the plant data in each set of plant data history information. A search means 15 searches for display data through the plant data table 3, plant data history information table 7 and long term search history information table 11, and a graph creation means 21 displays a graph on a display device 28.
