How to specify `margins` to `0mm` in RecipesBase.jl?

General Usage

If I want to create a recipe for my type with only RecipesBase.@recipe, I seem not to be able to specify all margins to be 0 or 0mm, where it requires a Measure type, which is defined in Plots.Measures module. How can I do that?

using RecipesBase

@recipe function f(data::Data)
    margins --> 0
    return data
end

julia> heatmap(data)
Error showing value of type Plots.Plot{Plots.GRBackend}:

The suggested way is writing:

using RecipesBase

@recipe function f(data::Matrix)
    margins --> (0, :mm)
    return data
end
