How to change granularity X-Axis of a chart to 1 sec (time series)

1

I have InfluxDb database with data feeded into it every 1 sec. This db is attached to graphana chart, but when I set group by time(1s) then no datapoints are not displayed. So how to set X-Axis time granularity to 1 sec?

PS. When I change my query to group by time (1m) then data are dsplayed

I found the solution. Data to the database was sent by the node Node-RED InfluxDb, in which the time accuracy was set to 1 minute.
