Display Loki metrics in daily/hourly buckets

Hi guys, first post here!

I’m using Grafana to tie together some metrics from various platforms, and part of our metrics are coming from raw logs stored in Loki. I’ve figured out how to display the number of matching log entries per day on a graph, but the rolling “day” starts/ends at the current time. In the attached example, I have selected a view of the last seven days at 08:27 on 2nd February, the daily blocks run from 08:27-08:27 for each day within my range, meaning data received before this time each day is moved into the previous day’s block.
Is there a way of binding my metrics so the day starts and ends at 00:00?
