[BUG] x and y seem to get switched around in recipe

[cjwyett]

struct MyType
    x::Vector{Float64}
    y::Vector{Float64}
end

@recipe function mytypeplot(::Type{T}, mytype::T) where T <: MyType
    mytype.x, mytype.y
end

mytype = MyType([-2., -1., 0., 1., 2.], [1., 2., 3., 4., 5.])

plot(mytype, label="@recipe")
plot!(mytype.x, mytype.y, label="plot()")

I would expect the final 2 lines to plot the same thing. Only I get this:

You should use a user recipe with the signature

@recipe function mytypeplot(mytype::T) where T <: MyType
    mytype.x, mytype.y
end

In the type recipe you have there the y-values are discarded, since it expects a single type whose recipe will be called and in your case, that is the standard recipe thats used for e.g. plot([-2, 1, 0, 1, 2])
