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:

  1. In the Graphics Display editor, double-click the trend to open the Trend Object Properties dialog box.
  2. Click the Pens tab.
  3. In the Type column of the pen you want to work with, select Full Width.
