Attach method of annotation not working for line chart

When I use attach method and specify X and Y values for a line chart the annotation does not show up. However for certain chart types(like bubble, OpenHighLowClose e.t.c) this shows up.

If I specify left and Top for annotation in a Line chart, it shows up but getting the proper left and top positions are a problem. Also setting the left and top postion will not take care of setting the annotation to proper position in case the form is resized.

What is the way out for positioning annotation for line chart?

Bar charts only support categorical X-Axis, so regardless of your X-Values, the attachment position must be expressed as an index in the X-Axis (0 for the first point, 1 for the second, etc.). In a line chart, the X-Axis is not categorical (if X-Values are passed) and therefore the attachment position is dependent on the X-Value and not on the point index.

ChartReport.Gallery = Gallery .Lines ;

Annotations annots = new Annotations ();

ChartReport.Extensions.Add(annots);

annots.EnableUI = true ;

annots.ToolBar.Visible = true ;

AnnotationText text = new AnnotationText ( "Katrina" );

text.Attach(2, 10);

text.Color = Color .LightBlue;

text.PlotAreaOnly = true ;

text.AllowMove = false ;

annots.List.Add(text);
