title: MSCHART Line graph annotation position
body: <p>Im wondering if anyone could help me with annotations im using in my MShart control.
  I have a line chart, at certain data plots within this chart I have annotations.</p>
  
  <pre><code>RactangleAnnotation a = new RectangleAnnotation();
  a.AnchorDataPoint = chart.Series["series1"].Points[i];
  </code></pre>
  
  <p>This places the annotation on my linechart at the position the data value is.
  What I need is to display this annotation, possibly at the top of my chart, and draw a line from myh annotation to the dataValue.</p>
  
  <p>Is this possible?</p>
