The base axis is always the horizontal axis in a scope view.

Alignment

Select your preferred position of the base axis scale from the pick-list.

Mode

In the preferences, only the "Time (X-T)" mode can be enabled.

The "Center around trigger" option, if enabled, always keeps the trigger level(s) in the middle of the view.

The "Value (X-Y)" mode is only available in the "Properties" dialog. It can be used for X-Y charts. The "Value" mode requires the selection of analog signals whose values are used for the base axis instead of time.

Like for trend graph view, you can set the notation and scaling mode.
