Add an axis to an existing graph by clicking one the Graph Tools | Add to Graph | Axis commands. These axes are not tied to the original plot, but they can be used in creating new plots on an existing graph or can be linked manually to an existing axis. To create a duplicate axis automatically linked to another axis on the graph, use the Graph Tools | Add to Graph | Duplicate Axis command instead.
To add a Y axis to a graph:

- Select the add axis command by clicking the Graph Tools | Add to Graph | Axis | Y Axis command.
- The Position Axis dialog opens. Make any changes and click the OK button.
- The new axis is added to the graph. Set additional axis properties in the Property Manager.
