Drawing Annotions at user click

[praveen.sekar]

How to create annotations at points where user clicked such that the centre of the object coincides with the point where user clicked ?

 I have the following code which draws a circle closer to the position.

public void drawBubble(double x, double y, double z)
{      
      Ellipse ellipse = new Ellipse();
      Annotations annotations = new Annotations();
  ellipse.Width = z;
  ellipse.Height = z;
  ellipse.Fill = Brushes.Blue;
  ellipse.Stroke = Brushes.Blue;
  ellipse.StrokeThickness = 10;
  Annotations.SetAttachX(ellipse, x);
  Annotations.SetAttachY(ellipse, y);
      annotations.Children.Add(ellipse);
     
}
