Hey! I have a overview of my 3 phases in my house. And how come when I use the 7 days period it wont show me the actual values?
Because in this example I had ampere uasge of 27 A during a short period of time this thursday 05/05. But when I select the 7 days period it show that it was max at around 15A that day… how come? This make this overview quite useless if you want to use it to monitor the actual usage over time. Is there any way to fix this?
what data source are you using?
do you think you could try and replicate this on our public sandbox, https://play.grafana.org?

I think I found the “problem”.
I was using “time($_interval)” at group by. So when I switched to 7 days each tick with mouse was like 10 minutes. And everything in between those 10 min wont be shown.
If I changed to 1 s in group by I saw all those “spikes”.
