Answer 1

Another two years later... this solution works for me, because I have no oxyplot models and I´m missing some of the named functions from above.

code behind:

public partial class LineChart : UserControl
{
    public LineChart()
    {
        InitializeComponent();

        DataContext = this;
        myChart.Title = "hier könnte Ihr Text stehen!";

        this.Points = new List();
        randomPoints();
    }


    public IList Points { get; private set; }

    public void randomPoints()
    {
        Random rd = new Random();
        String myText = "";

        int anz = rd.Next(30, 60);

        for (int i = 0; i < anz; i++)
            myText += i + "," + rd.Next(0, 99) + ";";

        myText = myText.Substring(0, myText.Length - 1);
        String[] splitText = myText.Split(';');

        for (int i = 0; i < splitText.Length; i++)
        {
            String[] tmp = splitText[i].Split(',');
            Points.Add(new DataPoint(Double.Parse(tmp[0].Trim()), Double.Parse(tmp[1].Trim())));
        }

        while (Points.Count > anz)
            Points.RemoveAt(0);

        myChart.InvalidatePlot(true);
    }
}

To update your data don't exchange the whole IList, rather add some new DataPoints to it and remove old ones at position 0.

XAML:

important are the x:Name="myChart" and ItemsSource="{Binding Points}"

I hope this is useful for someone out there
