How to set up a relative time and ajust points in the Graph in Grafana?

Hi everyone,

I’m facing an obstacle to set up my panel in Grafana. I have some tests done by different versions and different date and time, but I need to compare the results from versions.
I configured relative time to try show my results with same points in the graph, but in comparison the points are misaligned.

How can i align it? Can I define the time to start from 00h in graph instead of 19h30?

Thanks in advance guys
