As you can see in the illustrations below, the normal vector view of a waveform
displays the waveform data in dot mode: the waveform display is updated with
each acquisition to reflect the current data. In Fig 3--30, waveform database
display has been turned on and you can see the waveform data accumulation is
displayed all at once, with subsequent acquisition data being “added” to the
display as it is acquired.
