Abstract:
1. A method of indicating and manipulating a zoom region within a long data record comprising: displaying the long data record as a displayed waveform; in response to zoom data which defines a location and scale for the zoom region, displaying a zoom region indicator representing the zoom region with the displayed waveform, the zoom region indicator having a width and an independent associated marker which spans the width of the zoom region and has a length equal to or greater than the width of the zoom region, the length being greater than the width of the zoom region when the width is less than a specified dimension; simultaneously displaying with the displayed waveform a portion of the displayed waveform defined by the zoom region as a zoomed waveform; and manipulating the zoom region by moving the associated marker along the displayed waveform with a pointer device to display other portions of the displayed waveform as the zoomed waveform.
