Thank you. How do you covert the "where dropped" coordinates to data coordinates?
I assume by where dropped, you mean x,y coordinates within the chart. and by data coordinates, you mean x,y data in my dataProvider. I guess I need to dig in and understand drop coordinates in the chart. Drag n' Drop is well documented generically, but after a day of searching, I found no documentation on drag n' drop within a chart using chart data. I appreciate your help.
