Remove table name from graph legend

Hi
All searches didn’t help in my case to get rid of table name in graph legend eg: mail_power.L1 → L1 ( see picture)

Please look at the attached picture and advice me what I am doing wrong.

regards,

Ralf

Hi Ralf

You should be able to set the alias to $tag_alias to remove main_power.

Hi wroot365
Thank you for the answer. I am a pure beginner. After looking and reading several tutorials I still don’t understand where to set in the query the $tag_alias.
Can you give me a hint how to do that or give me a hint where to find an example/documentation how to do that?

It’s at the bottom to the right of FORMAT AS where it says ALIAS | Naming Pattern.
