Are you looking for doughnut type chart? Or do you want to draw over a existing chart?

You can handle the PostPaint event for the chart. Here, using e.Graphics.DrawEllipse method you can draw the circle at desired location.

I cant test this but IMHO half of the width and height of chart area will give you center coordinates relative to axes. You can then get the absolute coordinates using the Graphics object mentioned above.
