How set a day min time interval

Grafana
1

We are newbies with Grafana.

How can we set a day like min time interval? We know that we can set a min interval to a datasource but later, you can make zoom and then, you can watch data with more scale, like minutes and seconds. But we want that the min interval be a day.

On the other hand, how can we set timepicker to be able to choose an interval on the future?

Thanks in advance.

you can set min interval in the data source settings.

in time picker you can select an absolute range into the future using the date / calendar

By datasource setting, you mean set it in datasource setting of grafana UI or just the datasource, like in prometheus. I did not find any setting like this in grafana UI.
