Flux function fill() with influxdb 1.7.6

I do not exactly understand yourpoint. If you could explain it a bit more.
My pool temp measument has no values in the DB for a about a week. So both query with aggregateWindow(every: 3d, fn: mean) and without has null datapoints. Then fill() should behave similar. However it does not. Same query in th IQL is flawless but there you dont have and issue of order.
