* Change link arguments to ensure that they resolve correctly regardless of version Presently, the links take users to "latest" even if they are in other versions of documentation. Sometimes, the destination doesn't even exist in "latest".

Correlations
You can create interactive links for Explore visualizations to run queries related to presented data by setting up Correlations.
A correlation defines how data in one [data source]({{< relref "../../datasources" >}}) is used to query data in another data source. Some examples:
- an application name returned in a logs data source can be used to query metrics related to that application in a metrics data source, or
- a user name returned by an SQL data source can be used to query logs related to that particular user in a logs data source
[Explore]({{< relref "../../explore" >}}) takes user-defined correlations to display links inside the visualizations. You can click on a link to run the related query and see results in [Explore Split View]({{< relref "../../explore#split-and-compare" >}}).
Explore visualizations that currently support showing links based on correlations:
- [Logs Panel]({{< relref "./use-correlations-in-visualizations#correlations-in-logs-panel">}})
- [Table]({{< relref "./use-correlations-in-visualizations#correlations-in-table">}})
You can configure correlations using the Administration > Correlation page in Grafana or with [provisioning]({{< relref "../provisioning" >}}).
{{% admonition type="note" %}}
Correlations are available in Grafana 10.0+ as an opt-in beta feature.
Modify the Grafana [configuration file]({{< relref "../../setup-grafana/configure-grafana#configuration-file-location" >}}) to enable the correlations [feature toggle]({{< relref "../../setup-grafana/configure-grafana#feature_toggles" >}}) to use it.
