Hmmm, good point, you got me thinking/experimenting.
How (what mechanism) functionality could make this visualize/group it by days for example?
I can show it for a day now, but I would now need to repeat this for each day of the month. If i include more days in the timeframe Grafana comes back with a message saying the datapoints are too many.
By the way, I also noticed that when using State Timeline you need to implement a color tresholds yourself, which makes it not dynamic based on the values. I am not sure we are on the right way.
