Access to other data fields in data link


Grafana 7.3.7
Elasticsearch 7.0.1

I have some data that look like

“date”: …,
“value”: …,
“info_1”: …,
“info_2”: …

and I have made a date histogram of max metric based on value and grouped by info_1.

It works great but now I would like to add a data link for each point to display the info_2. However, only date, value, and info_1 are available as variable in the data link box.

Is there a way to have access to the info_2 field ?
