OxyPlot XAML unknown series count

Question

Is there a way, to bind the series of a OxyPlot in XAML, if I don't know, how many series I will have?

I know, that I can create a PlotModel, maybe I can bind a Collection of Series. But what I am realy looking for is, if I can bind the series to List of doubles.

Possible ItemSources examples:

ObservableCollection<Tupel<double, List<double>>> ItemSource1 { get; set; }

ObservableCollection<Tupel<double, double>> ItemSource2 { get; set; }

Possible Xaml Code:

<oxy:Plot>
 <oxy:LineSeries ItemSource="{Binding ItemSource}" />
</oxy:Plot>

I dind't find such a use case in the examples. Does someone have maybe a tipp for me?

No, there isn't.

As you have already discovered, you could create a PlotModel in your view model, and bind to and add series to this one.

There is a code sample available in the official docs:

public class MainViewModel
{
    public MainViewModel()
    {
        this.MyModel = new PlotModel { Title = "Example 1" };
        this.MyModel.Series.Add(new FunctionSeries(Math.Cos, 0, 10, 0.1, "cos(x)"));
    }

    public PlotModel MyModel { get; private set; }
}

XAML:

<oxy:PlotView Model="{Binding MyModel}"/>

If you don't want to use a PlotModel, you could create an attached behaviour that adds the series.
