Statistics' graph do not reflect the data

The problem

Hi
I can get the content of the statistics of my history_stat sensor temps_de_chauffe with an SQL query.

When I use the same data to generate a graph with the built-in graph, I do not find the same.

1. The time scale is not correct: It display the data of the 2nd of January on the 3rd of January
2. I selected 7 days to display and I have 8 days on the graph
3. The sum of the day are not correct for the 4 days on the left
4. Current day is missing.

If I use apexchart integration I have the correct values
