Hi,
I made a search about this subject but without success.
Is there detailed information (tutorial, URL, …) or commented examples on how works - as exactly as possible - the different aggregation, selector and so on (all possibilities in graph select query) ?
We use InfluxDB + Grafana, last version.
Thanks in advance
Best regards,
There is the official influxdb docs detailing the query language and functions, not sure what more there is
Thanks for answer.
I searched in Grafana doculentation. It is in InfkuxDB (https://docs.influxdata.com/influxdb/v1.3/query_language/functions/)
Now i have to read for my vacation, thanks 
best regards,
