With connection of a water temperature sensor, you can plot sea surface temperature
over time. Open the Layers menu and turn on [Temperature Graph]. The sea surface
temperature graph runs across the screen from right to left, the latest temperature at
the right edge. The temperature scale is at the left edge of the display. The unit of mea-
surement (°C or °F) can be selected with [Temperature] in the [Units] menu.
