Druid Plugin connectivity with Grafana

Hello All,
Can anyone please share any document or more detail about the Druid connectivity with Grafana and Druid plugin.

I am using below configuration
Druid v.0.14.0 / Grafana v6.2.1 / druid-datasource plugin 0.0.5

and Address of Druid server x.x.x.24:8088, broker x.x.x.22:8082.

Just want to know, What will be the connection-string and datasource addressed?

I am giving broker address with port but neither its giving any error or connecting.

Please note, I am very new to Grafana and Druid,

thnx
