Plot a value across the full width of the trend chart
Rather than plotting a pen value as individual point, you can plot its value as a horizontal line that extends across the full width of a trend chart. You might do this, for example, to establish high and low values as an alarm deadband on a trend chart.
To plot a tag value across the full width of a trend chart:
- In the Graphics Display editor, double-click the trend to open the Trend Object Properties dialog box.
- Click the Pens tab.
- In the Type column of the pen you want to work with, select Full Width.
