OxyPlot

Below is an example of an extension for OxyPlot. To use the extension:

1. Follow the instructions to add references and initialize renderers

2. Add a reference to the Fabulous.XamarinForms.OxyPlot package across your solution.

Here is an example translated from the OxyPlot documentation.

let plotModelCos =
    let model = PlotModel(Title = "Example 1")
    model.Series.Add(new OxyPlot.Series.FunctionSeries(Math.Cos, 0.0, 10.0, 0.1, "cos(x)"))
    model

let plotModelHeatMap =
    let model = PlotModel (Title = "Heatmap")
    model.Axes.Add(LinearColorAxis (Palette = OxyPalettes.Rainbow(100)))
    let singleData = [ for x in 0 .. 99 -> Math.Exp((-1.0 / 2.0) * Math.Pow(((double)x - 50.0) / 20.0, 2.0)) ]
    let data = Array2D.init 100 100 (fun x y -> singleData.[x] * singleData.[(y + 30) % 100] * 100.0)
    let heatMapSeries =
        HeatMapSeries(X0 = 0.0, X1 = 99.0, Y0 = 0.0, Y1 = 99.0, Interpolate = true,
                        RenderMethod = HeatMapRenderMethod.Bitmap, Data = data)
    model.Series.Add(heatMapSeries)
    model

let plotModels = [ plotModelCos; plotModelHeatMap ]

let view (model: Model) dispatch =
    View.CarouselPage(children=
        [ for m in plotModels ->
                View.ContentPage(content =
                View.PlotView(model=m,
                                horizontalOptions=LayoutOptions.FillAndExpand,
                                verticalOptions=LayoutOptions.FillAndExpand)) ])
