Double legend with twinx()

plotting

#1

I am trying to plot this:

plot(1:10, 1:10, seriestype = :bar, label = “1”, alpha = 0.4, legend = :left )
plot!(twinx(), 1:10, 501:510, label = “2”)

but I get two different legends and I want to get only one. (I moved the first legend to the left otherwise it is covered by the second one)
