What Grafana version and what operating system are you using?
Grafana 7.x / FreeBSD13
What are you trying to achieve?
I have a field called “email” e.g. email@example.com - I would like to use a “rename by regex” transformation to only grab the TLD from the email address.
My regex looks like this:
match: .*@(.*) replace: $1
It works - however I would like to create a pie chart grouping by this replace value.
My query is a count metric grouped by the email field.
However, the pie chart is not showing the grouped result.
