How to select a track history plotting interval
You can select the track history plotting interval from the times shown below. For long
plotting intervals, the time at which a point is added to the track is calculated by divid-
ing the total length in seconds by 20 (points). For example, a point is added every 18
s if the plotting interval is 6 m (360 divided by 20 is 18). The track history display is
reset when the plotting interval is changed.
