## Prepare to plot your Fuzzy sets

- Create points to use in plot packages using the chart_prepare

```julia
julia> input_a = Dict("small" => TriangularMF(1, 2, 3), "large" => TriangularMF(5, 6, 7));
julia> x = range(0, 8, length = 100);
julia> data = chart_prepare(ipa, x)
julia> using Plots
julia> plot(x, data["values"], label = data["names"])
