Grafana - Interval for getting values from a specific time

I need to display values in a graph in Grafana iteratively starting from a specific time. For example, you want to display data for the time interval 08:00AM - 08:00PM (with a difference of 12 hours). To calculate the values for the interval, the delta function is used. But at the moment, days are displayed starting from 00:00.

I tried to start drawing the data at 08:00PM but at midnight the graph was redrawn again. How can I adjust this 8 hours shift to draw values?
