Gadfly: how to add a legend to stacked plots?

Dear folks,

suppose we have two figures figA and figB which have the same legend. Is it possible to stack them together, e.g.,

newFig = hstack(figA, figB)

and to add only one legend to newFig afterwards (in my case centered in the bottom)?

Thank you in advance,

what’s wrong with adding Theme(key_position=:none) to FigA?
