Highcharts can be used free for non-commercial projects:

…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.

I use highcharts in my day job. Good, but expensive and not easily licensable for embedded. Open Source would also be a better fit.

I suspect that avoiding commercial charting libraries will limit our choice.

Maybe splitting the requirements into two would help (rather than trying to find one that does both):

1. Charts (bar, line, pie, etc)
   
   http://www.chartjs.org/
   https://gionkunz.github.io/chartist-js/index.html
   
   
2. Gauges
   
   https://canvas-gauges.com/
   

I’m certainly looking for something similar for the App side.

Steve,

yes, we definitely should include a charting lib, so we can do nice real time dashboards and statistics.

I need to check some new projects first. I've been using Flot for business backends, but it's become very outdated now.

New libs to check currently on my list:

- http://www.chartjs.org/
- https://gionkunz.github.io/chartist-js/index.html
- https://www.highcharts.com/
- https://www.fusioncharts.com/

Regards,
Michael

Michael,

Is there a graphing package that would be feasible to include in our web server?
