PROBLEM TO BE SOLVED: To provide a display device that allows a user to readily check the relation between the current status of a measured result being displayed on a trend screen and a set condition.SOLUTION: A setting range graph generating part 103 generates a setting range display graph, showing a numerical range, with a measured-value axis having the same scale as that of a measured value change graph. A display control part 104 displays the measured value change graph generated by a measured value graph generating part 101, an event occurrence display graph generated by an event occurrence graph generating part 102, and a setting range display graph generated by the setting range graph generating part 103 simultaneously on a display 109 as a trend screen.SELECTED DRAWING: Figure 1 |
