    Drawing a Polygon line by line using pointAnimation

    Hi, the program asks the user to input 4 x&y coordinates and from those points a polygon will be created line by line using animations. However, my program crashes after I inputted the 4 coordinates because of my PropertyPath declaration. Any idea on what should be the declared on the PropertyPath Value?

    NewPolygon = new Polygon();
    NewPolygon.Stroke = Brushes.Black;
    NewPolygon.StrokeThickness = 2;

    Storyboard sb = new Storyboard();
    PointAnimation pa1 = new PointAnimation();
    pa1.From=new Point(Xone, Yone);
    pa1.To = new Point(Xtwo, Ytwo);
    pa1.Duration = TimeSpan.FromSeconds(2);

    PointAnimation pa2 = new PointAnimation();
    pa2.From = new Point(Xtwo, Ytwo);
    pa2.To = new Point(Xthree, Ythree);
    pa2.Duration = TimeSpan.FromSeconds(2);

    PointAnimation pa3 = new PointAnimation();
    pa3.From = new Point(Xthree, Ythree);
    pa3.To = new Point(Xfour, Yfour);
    pa3.Duration = TimeSpan.FromSeconds(2);

    Storyboard.SetTargetProperty(pa1, new PropertyPath("(Xtwo, Ytwo)"));
    Storyboard.SetTargetProperty(pa1, new PropertyPath("(Xthree, Ythree)"));
    Storyboard.SetTargetProperty(pa1, new PropertyPath("(Xfour, Yfour)"));

    The error that pops out after entering the coordinates:
    An unhandled exception of type 'System.InvalidOperationException' occurred in PresentationFramework.dll

    Additional information: Cannot resolve all property references in the property path 'Point'. Verify that applicable objects support the properties.
