Detailed Description

Dashboard Plugin, display altitude trace.

Derived from Jean-Eudes Onfray's depth.cpp by Andreas Merz.

Since not every vessel is always on sea level, I found it sometimes interesting to observe the GPS altitude information. It can be extracted from the GGA nmea message.

Besides showing a rolling plot, the grid will auto-rescale to keep the plot within the visible range. The top line shows mean altitude and its standard deviation.
