How to make Y-axis Time series more accurate?


I have grafana 10.2 and my datasource is InfluxDB 2.0.9

I have a Time series on my energy consumption, but the Y-axis is not detailed at all.
As you can see, it shows 5 times the same value and also when I hover with the mouse, it’s the same.

They definitely are stored with more detail in InfluxDB as you can see

I have tried to change the y-axis for kwh to wh etc, but this only changes in factors of 10, not in ‘accuracy’.

If I look to the values timestamps, I also have the impression there is some time shift between my time axis in grafana and InfluxDB2.

Who can help me?
For more info, please ask.
