How do I find the delta between sum of values for two days with below query?

index=_internal type=usage idx=wineventlog | bucket span=1d _time | stats sum(b) as sum by h,_time

The above query gives the sum for "b" values over a period of one day. If I run the query for time period of two days I get two sums for "h". Difference between these two sums need to be found.

Thanks!

I found an alternative which worked for me-

index=_internal type=usage idx=wineventlog | chart sum(b) by h date_wday | eval diff=sunday-tuesday | eval diff=abs(diff) | sort -diff

the date_* fields are not considered authoritative from an accuracy standpoint, and your query will only work as long as you have queries less than one week (non-overlapping days of the week).
