I wanna dynamically change the placement offset of a label's background polygon. The hover text from that menu entry tells me: "Expected input: double coord [X,Y] as <= 0.0 =>". I have no clue what is meant by that and i am tired of messing around so could please someone replace appropriately the ? in the following expression:
CASE WHEN "HELP" > 9000 THEN ???? END
To make it more thrilling: i am also about to deal with negative decimal numbers here.
