@ -43,9 +43,9 @@ Panel titles and metric queries can refer to variables using two different synta
- `$varname`
This syntax is easy to read, but it does not allow you to use a variable in the middle of a word.
**Example:** apps.frontend.$server.requests.count
- `[[varname]]`
**Note:** This syntax might be deprecated in the future.
Example: apps.frontend.[[server]].requests.count
- `${var_name}` Use this syntax when you want to interpolate a variable in the middle of an expression.
- `${var_name:<format>}` This format gives you more control over how Grafana interpolates values. Refer to [Advanced variable format options]({{< relref "advanced-variable-format-options.md" >}}) for more detail on all the formatting types.
- `[[varname]]` Do not use. Deprecated old syntax, will be removed in a future release.
Before queries are sent to your data source the query is _interpolated_, meaning the variable is replaced with its current value. During
interpolation, the variable value might be _escaped_ in order to conform to the syntax of the query language and where it is used.
