I would like to know how to reduce the vertical spacing between the legends in the PlotLegend option.
In the answer to this similar question in How to change the spacing of line in legend? it suggests using the option "Spacings" in the method LineLegend. However, such an option seems to be abandoned at least in version 12.0, so what would be the way to achieve the same goal similar to the Spacings option now?
Spacings
shows up in Red and the popup says:Spacings is not an option for LineLegend
; but somehow it still works. $\endgroup$
