Adding alias (or grouping) breaks graph?

Hi,

I’m having trouble with a simple plot in Grafana.

I’ve got an influxdb that looks like this:

time                calibratedHumidity sensorname        temperature voltage
----                ------------------ ----------        ----------- -------
1635724024000000000 48.19              A4:C1:38:D2:DF:B1 20.41       2.949
1635724028000000000 48.19              A4:C1:38:D2:DF:B1 20.41       2.949
1635821657000000000 44                 A4:C1:38:43:7D:59 22          2.915
1635821658000000000 46.92              A4:C1:38:D2:DF:B1 21.95       2.898
1635821664000000000 44                 A4:C1:38:43:7D:59 21.9        2.915
1635821665000000000 46.98              A4:C1:38:D2:DF:B1 21.94       2.894
1635821674000000000 44                 A4:C1:38:43:7D:59 21.9        2.914

And I’m trying to make a plot with a meaningful legend, showing the colour that indicates the temperature and humidity for the two sensors (…DF:B1 and …7D:59)

At the moment, it comes up as shown here “temp.mean” and “temp.mean” for both temperature and humidity.

If I add any alias to the query, the line of data for that query disappears.

If I try to ‘group by’ tag(sensorname), the line of data for that query disappears.

Is this expected behaviour?

Thanks,
R

For some reason, the behaviour isn’t showing up today. See screenshot below:
