HORizontal:MAIn:REFPoint
This command sets or queries the horizontal reference point for the Main
timebase. The horizontal reference point is the horizontal position around which

which affects the acquired and observable horizontal window of data. The
horizontal reference position is set as a fraction of the record; 0.5 (50% of the
record) i s the default.
This command is equivalent to setting a value in the Horizontal Reference
control in the Timebase section of the Horizontal Setup dialog box or moving the
Horizontal Reference Point indicator at the top of the Main view.

reference point, time o f first point, time of last point, and horizontal position.
