Is there a chart series class, that can be used as a base for implementing a graphic, similar to the one in this picture?
We’ve already dealth with displaying the external labels in a pie chart. I’m asking only about the overlapping area circles. The data point circle radius needs to lay on the circumference of another circle, concentric to the border, having a radius equal to 1/3 of the border radius. We are currently modifying a pie chart but are looking for a more out-of-the-box solution.
Thanks in advance!
