I am using OxyPlot to draw some diagrams in my .NET WPF project. MVVM is a new thing to me, so i am not sure how to follow it in this situation.

1. There is a window (main view) that contains PlotView.
2. There is a model that contains a collection of objects. Each object corresponds to a graph on my plot.
3. There is a view model which creates LineSeries, puts it into PlotModel.

The problem is that i want each graph to be clickable. After a click another window opens with more detailed information on the corresponding object. My current view model is something like this:

public class MainViewModel : BaseViewModel
{
    public PlotModel MyPlotModel { get; set; }

    private MyModel model;


    public MainViewModel()
    {
        model = new MyModel();
        DrawGraphs();
    }


    private void DrawGraphs()
    {
        List<MyObject> myObjects = model.GetObjects();

        foreach (var obj in myObjects)
        {
            var s = new LineSeries();
    
            // Setting up datapoints and appearance of the graph

            s.MouseDown += (object sender, OxyMouseDownEventArgs e) =>
            {
                var view = new ObjectView(); // A view with full information of this specific object
                view.DataContext = new ObjectViewModel(obj); // View model uses the object as a parameter to do bindings for new view
                view.ShowDialog();
            };
            MyPlotModel.Series.Add(s);
        }

        OnPropertyChanged("MyPlotModel");
    }
}

MouseDown can be set up only on series creation because i need to know a specific object from my model that corresponds to this graph.

It works fine to me, however, i doubt that implementation follows MVVM. View model should not be able to create new views. But i cannot come up with a better solution. Is there a more elegant and MVVM-ish way to do this?
