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.

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
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 I've been using Flot for business backends, but it's become very outdated now.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?
