I applied a transformation to join the query results using the time field. Now I can run calculations, combine, and organize the results in this new table.

Use this transformation to rename parts of the query results using a regular expression and replacement pattern.
You can specify a regular expression, which is only applied to matches, along with a replacement pattern that support back references. For example, let's imagine you're visualizing CPU usage per host and you want to remove the domain name. You could set the regex to '([^.]+)..+' and the replacement pattern to '$1', 'web-01.example.com' would become 'web-01'.
You can specify a regular expression, which is only applied to matches, along with a replacement pattern that support back references. For example, let's imagine you're visualizing CPU usage per host and you want to remove the domain name. You could set the regex to '/^([^.]+).\*/' and the replacement pattern to '$1', 'web-01.example.com' would become 'web-01'.
In the following example, we are stripping the prefix from event types. In the before image, you can see everything is prefixed with 'system.'
> **Note:** The Rename by regex transformation was improved in Grafana v9.0.0 to allow global patterns of the form '/<stringToReplace>/g'. Depending on the regex match used, this may cause some transformations to behave slightly differently. You can guarantee the same behavior as before by wrapping the match string in forward slashes '(/)', e.g. '(._)' would become '/(._)/'.
