Average bucket in histogram change when time filter change

Let me get back to this:

1. I was mostly looking at the JSON query and response since those are much easier to figure out than the Lens screenshot.

2. If you switch the bucket size from day to week, I'm not surprised the results change — you are moving from average per day to average per week, which is different.

3. I'm not sure how you want to get the daily average out of a pie chart. Shouldn't that be a bar chart with one bar per day? Like this:

   I have a different dataset, but daily average:
   

   

   With special care to make the buckets 1 day each (click on the @timestamp field to pick this interval):
   

   

PS: 20MB for one index is very small — you're having a lot of overhead just from the amount of shards. Either switch to monthly indices or use ILM to create them with 50GB each.
