# Data links

Data links allow you to provide more granular context to your links. You can create links that include the series name or even the value under the cursor. For example, if your visualization showed four servers, you could add a data link to one or two of them.

The link itself is accessible in different ways depending on the visualization. For the graph you need to click on a data point or line, for a panel like
Stat, Gauge, or Bar Gauge you can click anywhere on the visualization to open the context menu.

>**Note:** For stat, gauge, bar gauge, and table visualizations, you add and edit data links on the Field tab. For the graph visualization, you add and edit data links on the Panel tab.

You can use variables in data links to send people to a detailed dashboard with preserved data filters. For example, you could use variables to specify a time range, series, and variable selection. For more information, refer to [Data link variables]({{< relref "data-link-variables.md" >}}).

## Add a data link

1. Hover your cursor over the panel that you want to add a link to and then press `e`. Or click the dropdown arrow next to the panel title and then click **Edit**.
1. On the Field tab, scroll down to the Data links section. (Panel tab for graph visualizations.)
1. Expand Data links and then click **Add link**.
1. Enter a **Title**. **Title** is a human-readable label for the link that will be displayed in the UI.
1. Enter the **URL** you want to link to.
   
   You can even add one of the template variables defined in the dashboard. Click in the **URL** field and then type `$` or press Ctrl+Space or Cmd+Space to see a list of available variables. By adding template variables to your panel link, the link sends the user to the right context, with the relevant variables already set. For more information, refer to [Data link variables]({{< relref "data-link-variables.md" >}}).
