No visible graph with InfluxDB

Hi, I am using Grafana wiht InfluxDB.
I’ve got one query, that delivers values.
But there is no graph on my Panel. If I switch to Table , i can see all the values with time.
I also see the time when I hover the Panel .

Any Ideas how to fix it ?


You’ll need to put the values into the database as numbers, not strings.

“24.8” is a number, “24.8°C” is a string.
