Maintain 1 minute granularity for 1 month of data CSV export

I have a panel pulling availability (up, for instance_). If I export several days of data to a CSV, I retain the 1 minute granularity, but if I extend the time window, granularity drops accordingly. 1 week of data reduces granularity to 15 minutes, and 1 month increases it to 1 hour. Can this be overridden? I get that this is probably an export size issue, but still need it. Thanks.

What datasource are you using?

In this use case data source is Prometheus.

this is because grafana only query from promteus the number of data suitable for viewing according to the resolution of the screen. I’m not familiar with prometeus, I don’t know if you can change this interval.
