One gauge to rule them all - provides all the information a sailor needs on one display
- SOG - speed over ground (meters per second)
- COG - course over ground
- DBT - depth below transducer (meters)
- reverse laylines, eg. 'how high can I point'
- apparent & true wind m/s (true calculated if the data feed doesn't contain it)
- distance and direction of mark/waypoint (if feed has it)
Depth reading has also a small sparkline. Depth figure starts to grow under 6 meters and turns red under 3 meters.
You can just download SailGauge from Github or install it with Bower
bower install https://github.com/SignalK/sailgauge.git
SailGauge package contains all the js libraries it uses so it is ready to use out of the box, but it needs data from a SignalK server. It tries to contact SignalK server on the same server & port from which it was loaded.
If you want it to contact some other server you need to edit the index.html.
Install the js dependencies with
npm install
and then package the js code that is not part of the html page with
npm run build
Development time building with npm run watch.
