Change the Y scale
Click the small faceplate of the trended parameter for which you want to see the Y scale.
The Y scale displayed on the left side of the trend area changes to the selection.
For Controlled Variable faceplates, repeat step 1 to alternately display the Setpoint scale if this parameter is being trended.
Note
By default, only one Y scale is displayed to maximize the chart size.
