ABSTRACT:
A method of indicating and manipulating a zoom region of a waveform being displayed includes a zoom region indicator. The zoom region indicator has an associated marker that spans the zoom region but is never less than a minimum span to allow ease of identifying or locating the zoom region on the displayed waveform. Manipulating the associated marker with a pointer device causes the zoom region to move accordingly along the displayed waveform. The portion of the displayed waveform that is within the zoom region is displayed as a zoomed waveform on the display.
