Change the Display High and Low Span in View

By default, WebAccess uses the High Span and Low Span of the Tag.  Users can change the Display High and Low Span to "zoom in" or "zoom out" of trend data.

1.      Select a Tagname by clicking on the colored square.

2.      Click Display Low

3.      A Change Dialog Box opens

4.      Type a new number for Display Low or use the ramp keys or slider.

5.      Click Enter.

6.      Repeat for Display High.

If you leave this RealTime Trend Group, the default Display Low and Display High will be used.
