# URL variables
You can use variables in data links to link to specific portions of your visualizations. For more information about data links, refer to [Data links]({{< relref "../linking/data-links.md" >}}).
> **Note:** 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.
## Typeahead suggestions
Press Cmd+Space or Ctrl+Space on your keyboard to open the typeahead suggestions to more easily add variables to your URL.

## Time variables
* ``__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.
