Abstract

PROBLEM TO BE SOLVED: To improve a monitoring property by displaying the scale of a trend graph being selected and specified together on the side surface of a trend graph screen. SOLUTION: A trend graph is displayed on a CRT by a CPU and a display device (CRT). A graph scale presses down a cursor travel key 13 when a channel 1 (generation power) is displayed and then the scale of a channel 2 (vacuum in an exhaust room) is displayed. Then, pressing of the cursor travel key 13 is transferred from a keyboard to the CPU via a keyboard controller. Then, the scale display of the trend graph is changed from a channel (n) to a channel n+1 in the CPU. Further, the scale 12 is moved from the channel n to the channel n+1 in the CPU. In this manner, the scale of the trend graph being selected and specified is displayed together on the side surface of the graph screen, thus obtaining a device with an improved monitoring property.
