title: How to let user create Annotations on MSChart?
body: <p>How do you create an Annotation on-the-run and how do you enable end-user placement with <code>Annotation.BeginPlacement()</code>? I've tried to do this in multiple ways, but cannot get it working. It should render itself in real-time after the BeginPlacement() has been called.</p>
  
  <p>Documentations on this subject is little to none - and mostly none - so I'm not able to find any help for this problem.</p>
  
  <p>What I've tried so far, is to create an annotation and place it with AnchorX/Y, set all Allow- flags to true and called BeginPlacement() while mouse is moving, but cannot see the annotation while placing it nor will it go in it's place accordingly. For example, LineAnnotation starts in right position, but doesn't end where I left it. When I move it so it starts from my ChartAreas {0,0}, it will hit the end-point.</p>
  
  <p>What I want to know, is when and how to use these tools available? What I am trying to do, is to let the user draw annotations on a chart and use as tools when analyzing the charts.</p>
