Hi all,
I’m showing a temperature from a sensor.
entity: sensor.netatmo_jt_aussen_temperature
graph: line
name: Außen West
type: sensor
unit: ' '
Works so far. However sometimes the value is a full number e.g. 3. In this case, the digit right of the decimal separator are not shown. This looks not so nice when you show a lot of temperatures on the dashboard and all other play nice and have the digit. Is it possible to show it as (e.g.) 3.0 instead of 3? And if yes, how? 
Thanks,
Johannes
