The issue does not seem to occur on all devices.
I was able to reproduce the problem as follows:
Here I selected a temperature sensor on a probe that detects if there is a water leak (Water Leak Sensor (Temperature))
Adding a chart.
Select a device with a temperature that has only one value
Select chart type: Area
Show axes: Yes
Aggregation function: Average
Group by: Hour (Also tested with Do not group)
Show variation: Yes
Default interval: 24h
And Save
I was able to see this in the console:

I tried exactly the same case as you, and everything works. Can you give me more details on how to reproduce it?
