Display multiple Y (vertical) scales on a graph

By default, a single Y scale (vertical axis) displays on the graph and it changes each time a faceplate or parameter is selected. (The Y scale matches the last selected faceplate or parameter in the Legend.) However, you can add multiple Y scales to the graph.

  1. Click Trend → Legend Enabled to enable the Legend. (Select a few parameter references and notice that with each selection, the Y scale changes to match the last selected parameter.)
  2. Hold down the CTRL key, and then select the parameter references for which you want to show Y scales. (Select the parameter references from the Legend.)
  3. Right-click, and select Y Axis Display → Show Left Axis.

The Y scales display for the selected parameters.
