I fixed it with a workaround. I wrote a function that check if all data have the same month and year and set unit time to: day, otherwise set unit time to: month.

Labels are added at start if unit. No month starts in the example period.

I don't think this is a bug. But this could be turned into an enhancement request, for placing the labels in the middle of the unit.

I don't think there is anything we can do about this. If the automatic unit selection does not work correctly, that could be altered, but when config states unit, chart will obey that.
