<p>PURPOSE: To intuitively designate and change the range of a trend graph while looking at a window display. CONSTITUTION: When it is desired to change the trend range of a trend graph which is shown at a trend graph display part 6, the trend range is shown in a window of the part 6. Then the present trend range of the trend graph is operated through a trend range display operation part 11 and outputted to a data conversion display control part 5. Thus the part 5 performs the control to show each trend data at the part 6 as a trend graph in response to the trend range given from the part 11.</p> |
