Data link variables

You can use variables in data links to refer to series fields, labels, and values. For more information about data links, refer to Data links.

To see a list of available variables, type $ in the data link URL field to see a list of variables that you can use.

Note: These variables changed in 6.4 so if you have an older version of Grafana, then use the version picker to select docs for an older version of Grafana.

You can also use template variables in your data links URLs, refer to Templates and variables for more information on template variables.
