Almanac, Environmental, and On-boat Data
Various sensors, transducers, or antennas are required to capture the data displayed on the graphs. For
information about connecting the chartplotter to peripheral devices using a NMEA 2000 network, see
Technical Reference for Garmin NMEA 2000 Products, on the included CD.
Conguring 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 specic
maximum and minimum values.
1. From the Home screen, select > .
2. Select a type of graph (, , , , or ).
3. Select .
4. Complete an action:
• Select , and select or to set the duration.
• Select . Select , , or. When you select , the chartplotter sets the optimal
minimum and maximum values for the range, based on environmental conditions. When the
chartplotter receives new data about environmental conditions, it adjusts the scale automatically.
• Select to allow the chartplotter to set the optimal minimum and maximum values for the
range, based on environmental conditions.
Wind Speed Data
Viewing the Wind Speed Graph
The chartplotter must be connected to the peripheral devices listed below to capture the data shown on the
wind speed graph.
