Example
If the vertical scale is changed when the Expand
function is set to ground, the signal will expand
from the ground level*. The ground level does not
change when the vertical scale is changed.
If the vertical scale is changed when the Expand
function is set to center, the signal will expand from
the center of the signal. The ground level will suit
to match the signal position.
*Or from the upper or lower edge of the screen if
the ground level is off screen.
