Data link for time series graph

Hello everyone,

I am on Grafana v8.4.3 on a Windows operating system.

My Grafana dashboard uses an InfluxDB bucket as a datasource, the measurements of this bucket have a tag named DAY_AGGREGATION.

With a SQL query, I retrieve the SCORE value and the associated DAY_AGGREGATION tags. I know that the query works because I can see the tags in the table view:

So, in the time series view I would like to create a data link that pass the DAY_AGGREGATION tag associated to the SCORE value that I click:

I tried several variables with the $ operator, but none of them worked.

Do you know what I must do to perform this please?

Thanks in advance
