Cannnot add a trace to visualisation via Series tab

[reflection95]

Hi, I would like to add a line to my barplot, and I found on web this should be done via Series tab in Redash, but there is no option to add any series. my query returns necessary series. i tried prividing them to 'Y column', 'errors column', but actually only specifying something in "group by" field of editor populates Series tab.
Do i have to enable the feature somehow?

Redash version 10.1.0

I am closing this since I realized the option as available in the case "group by" field in visualization tab is not used.
