From this question, I understand that a type recipe is for plotting a specific type with a wider range of signatures. However, I cannot add an hline in the figure within a recipe.
using RecipesBase: @recipe, @series
struct MyWrapper
v::Vector
end
@recipe function f(::Type{MyWrapper}, mw::MyWrapper)
@series begin
seriestype --> :hline
seriescolor := :black
z_order --> :back
zeros(1)
end
return mw.v
end
However, I cannot plot anything from it:
x = MyWrapper(cumsum(rand(10)))
plot(x)
julia> plot(1:10, x)
Error showing value of type Plots.Plot{Plots.GRBackend}:
