[BUG] Buggy `link` behavior

[yuvalwas]

Details

link only links the first two subplots. Furthermore, using layout breaks it.

x = range(1, 10, 10)
y = range(1, 5, 10)
z = range(1, 2, 10)

plot(plot(x), plot(y), plot(z), link=:y)

plot(plot(x), plot(y), plot(z), link=:y, layout=(3,1))

Correct me if I'm wrong, but isn't this documented behavior? link=:y links the y axes in each column. When you specify layout=(3, 1) there is only one column, and so there are no other y axes to link. Specifying link=:all links all axes in all subplots.

With that said, it would be nice to be able to link the y axes in all subplots without also having to link the x axes. Is there a way of doing that without manually providing ylims for each subplot?

[yuvalwas]

Yes, I guess that at the time I thought it is supposed to do the latter. It would be nice to be able to link whatever axis across any subset of subplots.
