Using the Multi Pens Trend at Runtime

You can change the behavior of the Multi Pens Trend in runtime in WindowViewer. For example; adding pens, deleting pens or playing historical trend data. The Multi Pens Trend can be organized in 3 areas:

• Top Header: Lists the pen details in a table format

• Trend Area: The pens are visually represented in this area

• Toolbar: Contains the playback and stacking options

  

Cursor Readout Dialog

The cursor readout dialog displays the following fields; Pen Name, Value, Quality and Engineering Units when the cursor is placed at a specific point on a pen; i.e. at a specified time. To view the cursor readout dialog, hover the cursor on the Trend Area.

Displaying Data Quality

The style of the trend pen changes to a Bad Quality style when the reference does not have good quality data. The trend will continue to display using the last known good value. The style can be changed using Galaxy Styles in System Platform IDE.
