OxyPlot SVG Rendering

All we need to do is reference the OxyPlot.Core NuGet package.

#r "OxyPlot"

Import a few namespaces that our SVG provider will need.

using System.Text;
using Xamarin.Interactive.Representations;
using OxyPlot;

We can now write the representation provider which will be called whenever a PlotModel object is the result of a cell’s execution. This is our opportunity to provide a custom representation of that object.

InteractiveAgent.RepresentationManager.AddProvider<PlotModel> (plotModel => {
    var exporter = new SvgExporter {
        Width = 300,
        Height = 250
    };

    var svgUri = "data:image/svg+xml;utf8," + exporter.ExportToString (plotModel);

    return new Image (
        Xamarin.Interactive.Representations.ImageFormat.Uri,
        Encoding.UTF8.GetBytes (svgUri),
        (int)exporter.Width,
        (int)exporter.Height);
})

Finally, we can begin using the actual OxyPlot API. First we create a model, and then add a data series to it.

using OxyPlot.Series;

var plot = new PlotModel ();
plot.Series.Add (new FunctionSeries (Math.Sin, -10, 10, 0.1, "sin(x)"));
plot.Series.Add (new FunctionSeries (Math.Cos, -10, 10, 0.1, "cos(x)"));
plot.Series.Add (new FunctionSeries (t => 5 * Math.Cos (t), t => 5 * Math.Sin (t), 0, 2 * Math.PI, 0.1, "5cos(t),5sin(t)"));

And finally render the result by ensuring the cell yields a PlotModel object as its last result.
