Description

I have multiple plots in one figure, and I want to toggle their visibility. But when I set legendonly, it removes the item completely from hover event data, and I cannot keep track of my plots anymore using their index. How can I preserve the hover event data for hidden plots? I need the hover event data for a custom legend component.

Research direction

Reproduce the issue with multiple plots, legendonly visibility, and a custom legend, then trace how hidden plots are handled when hover event data is assembled. Done means hidden plots remain identifiable in hover event data while their legendonly visibility is preserved.
