What Grafana version and what operating system are you using?
Grafana 9.2.3 running in a docker container on debian host
What are you trying to achieve?
I want to Display a Bar chart that shows durations (Hours:minutes) on the y-axis
How are you trying to achieve it?
I have a duration field (interval) from a postgres datasource.
The query is a bit more complex, the relevant select part is this:
SELECT time, EXTRACT(epoch FROM duration)*1000 as duration, ---...
First I divided the duration/epoch by 3600, so I would get a float that represents hours.
However this leads to the y Axis and the bar-labels showing values like 5.5 where I would prefer to read 5:30 if possible.
To solve this, I am tried to use the following custom unit in Standard options:
and since the input for custom time: formats apparently expects milliseconds, I am multiplying the epoch value by 1000
The duration is interpreted as time with a timezone.
The local timezone is used (CET which is +1h right now) and consequently a duration of 0 is displayed as 1:00 (i.e. one hour) instead of 0
What did you expect to happen?
I would LIKE the value to be interpreted as duration, effectively to ignore the timezone, or simply overwrite it with UT such that 0 is 0.
