[Ovmsdev] Chart lib for the web UI (was Re: Auto start/init)

[Michael Balzer]

Highcharts can be used free for non-commercial projects:

https://www.highcharts.com/products/highcharts/#non-commercial

…but is quite fat, as well as chart.js and FusionCharts.

Chartist-js is my current preference.

Gauges can be done otherwise, but they also don't need to be super fancy. Canvas Gauges needs 13 kB gzipped, which is quite a lot for just gauges.

http://bernii.github.io/gauge.js/ would be my choice, that's just 4.8 kB gzipped. Maybe the gauge charts in chartist-js even are sufficient, with some extra
lines of code to add a pointer, but another 4.8 kB wouldn't hurt too much given the just 10 kB of chartist.

Regards,
Michael
