I just started with grafana and would like to try to develop my own plugin to use it beside Graph, Singlestat, Dashlist, and Text panels. I found only these links about that :
http://docs.grafana.org/plugins/panels/,
https://grafana.net/resources/getting-started-with-plugins
Is anybody have ideas which environment could be used for developing grafana plugin and from where possible to start?
Thank you
There is a detailed walkthrough of the creation of the Clock panel plugin available on the grafana blog: Part 1 & Part 2
That's definitely a good place to start. As far an an environment, you'll obviously need a grafana instance, and you'll also need node & npm to be able to run the grunt-based build process.
Part 1 of the walkthrough should have enough detail to get you started, there is also a pretty active community on the grafana irc and slack channels who can help with specific questions.
