Does Prometheus 2 still use the unmaintained charting library "flot charts" ?

http://www.flotcharts.org/

No commits since 2014. Unfortunately, because it's a great chart library (actually probably the best free one), only the reliance on JQuery isn't that fashionable.

Edit: oh, it was Grafana and Kibana that used Flot charts (at least when I tried it two years ago, maybe things have changed) quick Google (2014): https://github.com/grafana/grafana/issues/222

No, we never used flot charts. We're using Rickshaw since the beginning: http://code.shutterstock.com/rickshaw/

It was unmaintained for a while, but now it seems there've been commits in the recent past again. However, for real dashboarding (not just simple ad-hoc queries), we recommend using Grafana anyway.

This is one of the other "better" charting libraries, and it is maintained: http://nvd3.org/
