The Four-Pen Trend object shows between 1 and 4 Equipment Trend Items trended on the same set of axes.
The tag names corresponding to each displayed Equipment Trend Item are shown across the top of the graph. The box surrounding each tagname matches the line style and color of the trend line for that Equipment Trend Item. At runtime when you hover the mouse cursor over the boxes, the full Equipment Name is displayed. Above each box, flags are displayed to indicate the full range.
The number of vertical gridlines and the corresponding text indicating the time intervals (i.e., 1h, 2h, 3h, etc.) depends upon the Time Span selected in the Presentation Options for the trend.
If the trend has fewer than 4 displayed Equipment Trend Items, the objects associated with the remaining items are not displayed.
Alarming is based on the referenced equipment.
