  Hi there. Is there a way to draw a polygon in an annotation but not have it positioned absolutely? I need to draw one positioned relative to the data point index, in the same way the ellipse is in your sample.

  Hello,

  In order to create a polygon annotation with a relative position, you need to set the attachment property to Relative. You also need to provide the coordinates of all the points of the polygon relative to the chart.
  
  Please refer to the sample attached.
