Whats with the yellow line?

[Fralle]

It’s been a while since I last fiddled with PEQ, and I’ve noticed there’s a yellow line now. What exactly does it represent, and what does it mean?"

It is the curve of the currently selected band. Band 1 (PK1) is selected, meaning the curve of PK1. If Band 2 is selected, the number in the graphic should change to '2' and the curve of PK2 should be displayed.
