Hi @zolora
I don't know what you mean by "concat", but I'm guessing you are combining several questions on a dashboard.

Yes, I use the "Edit data" and add two questions.

@zolora You can change column names by hovering the card on dashboard > Visualization options.

When I put blank field like this :

I have right labels in pop-up, but as soon as I add a caption they become wrong. Moreover I have already filled in "labels" with what I want

@zolora I don't understand what you are trying to do, but Metabase does not support split Y-axis configuration (, and only gets information from the first question to define the combined chart (
There's no simple solution for those.
Create a single question, which contains all the data instead of combining multiple questions, that's likely the only solution.

Okay thank you for your help
