Hi @Redcxx as @wylie it most likely has to do last bucket vs entire time range.

I just had a fairly extensive conversation on this / very similar topic [here](https://discuss.elastic.co/t/tsvb-value-is-0-when-time-filter-set-to-today-and-data-time-range-mode-set-to-last-value/246719)

You might find a deeper explanation there
