# Data links
{{< docs-imagebox img="/img/docs/v66/datalinks_graph.png" max-width="1025px" caption="Data links" >}}
Data link allows adding dynamic links to the visualization. Those links can link to either another dashboard or to an external URL.
{{< docs-imagebox img="/img/docs/v66/datalinks.png" max-width="1025px" caption="Data links" >}}
Data link is defined by title, URL and a setting whether or not it should be opened in a new window.
* **Title** is a human readable label for the link that will be displayed in the UI.
* **URL** field allows the URL configuration for a given link. Apart from regular query params it also supports built-in variables and dashboard variables that you can choose from
available suggestions:
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.
Example with Bar Gauge panel

## Variables to use in your URL
> These variables changed in 6.4 so if you have an older version of Grafana please use the version picker to select
docs for an older version of Grafana.
* ``__url_time_range`` - current dashboard's time range (i.e. ``?from=now-6h&to=now``)
* ``__from`` - current dashboard's time range from value
* ``__to`` - current dashboard's time range to value
### Series variables
Series specific variables are available under ``__series`` namespace:
* ``__series.name`` - series name to the URL
* ``__series.labels.<LABEL>`` - label's value to the URL. If your label contains dots use ``__series.labels["<LABEL>"]`` syntax
### Field variables
Field specific variables are available under ``__field`` namespace:
* ``__field.name`` - field name to the URL
### Value variables
Value specific variables are available under ``__value`` namespace:
* ``__value.time`` - value's timestamp (Unix ms epoch) to the URL (i.e. ``?time=1560268814105``)
* ``__value.raw`` - raw value
* ``__value.numeric`` - numeric representation of a value
* ``__value.text`` - text representation of a value
* ``__value.calc`` - calculation name if the value is result of calculation
### Template variables
When linking to another dashboard that uses template variables, you can use ``var-myvar=${myvar}`` syntax (where ``myvar`` is a name of template variable)
to use current dashboard's variable value. If you want to add all of the current dashboard's variables to the URL use ``__all_variables`` variable.
## Typeahead suggestions
Hit CMD or CTRL space on your keyboard to open the typeahead suggestions to more easily add variables to your URL.
