*Summary:* This example shows how to create Images and add them to the Charts in F#.

Let's first create some data for the purpose of creating example charts:

*)

open Plotly.NET

let x = [ 1.; 2.; 3.; 4.; 5.; 6.; 7.; 8.; 9.; 10. ]
let y = [ 2.; 1.5; 5.; 1.5; 3.; 2.5; 2.5; 1.5; 3.5; 1. ]

(**
Use the `LayoutImage.init` function to generate an image, and either the `Chart.withLayoutImage` or the `Chart.withLayoutImages` function to add
multiple annotations at once.

*)

open Plotly.NET.LayoutObjects

let image =
    LayoutImage.init (
        Source = "https://fsharp.org/img/logo/fsharp.svg",
        XRef = "x",
        YRef = "y",
        X = 4,
        Y = 4,
        SizeX = 5,
        SizeY = 3,
        Sizing = StyleParam.LayoutImageSizing.Stretch,
        Opacity = 0.5,
        Layer = StyleParam.Layer.Below
    )

let imageChart =
    Chart.Line(x = x, y = y, Name = "line") |> Chart.withLayoutImage (image)

(*** condition: ipynb ***)
#if IPYNB
imageChart
#endif // IPYNB
