How to change X-Axis time granurity to 1 sec?


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 dataare not displayed. So how to set X-Axis time granularity to 1 sec?

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