Spline curve

[Sadique-The-Alchemist]

can draw a spline curve by using x and y

if the opts contains color attribute it will return an area spline, to give color to the line use edge_color on opts

def spline() do
    x_nx = Nx.linspace(0, 10, n: 100)
    x = Nx.to_list(x_nx)
    y = x_nx |> Nx.sin() |> Nx.to_list()


    Matplotex.spline(x, y, x_label: "X", y_label: "Y", edge_color: "green")
    |> Matplotex.show()
    |> copy()
  end
