Is it possible to change the scale of a TREND within PowerLogic SCADA?

To modify the scale of the X or Y axis of a trend displayed in a Process Analyst, use the Edit Span or Edit Vertical button. If the Process Analyst currently does not display corresponding buttons for Edit Span and Edit Vertical in the toolbar, a user can add them by clicking on the Show Properties button and selecting the Toolbars tab. Locate Edit Span and Edit Vertical in the Available Toolbar Buttons window and move them to the right.
