Technical Reference for Garmin NMEA 2000 Products, on the included CD.
Configuring a Graph
You can set the scale and duration of each graph. The duration represents the time interval that appears on the
graph, and the scale represents the range of the measured data that appears on the graph, including specific
maximum and minimum values.
