Bar Chart displays wrong x axis values

Grafana version : 10.3.3 (Debian 12)

I would like Bar chart displays days instead of hours as below in x axis :



Do you know how to proceed ?

I have tried this solution found in the forum but it does not work, this does not change the values in the table, as if the original value was not a true date/time value.

Thanks for your help.

This is a similar problem to one I raised a few days ago.
