Grafana cloud - loki - time series - X axis

Hello, I integrate logs into loki via API in grafana cloud.
Here is an example in loki:
Labels column:
{ “Date”: “10/09/2024 10:34:51”, “System”: “application1”, “Type”: “kpi_metier”, “Value”: “800070”, “job”: “kpi_metier”, “service_name”: “kpi_metier”, “service_name_extracted”: “unknown_service” }

In the Time Series graph, I want to use for the X axis the Date contained in the label column and not in the Time column.

How should I proceed?

thank you in advance
