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

[Mark Webb-Johnson]

Chartist-js seems fine for what we need.

For gauges, I am talking about something like Torque. The ability to create a dashboard with gauges mapped to metrics. Useful both on web and on Apps. Anyway, not at all urgent or high priority.

Regards, Mark.

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.
