I am really sorry to hear about your frustration. I hope I can shed some light on the situation and thus ensure you that we are actually going forward.
A while ago we took a step back and re-evaluated the needs of our customers and how our charting solution (RadChart) measured up those needs. The decision that we came upon was not an easy one - most customers would have us work on the performance and flexibility of RadChart and the control had its limitations. Nevertheless, we stood by our decision and the result was a new control - RadChartView. You can find a detailed comparison between the two controls in our online documentation
. And indeed, we put the focus of this new control on performance, flexibility and ease of use and now, almost 3 years later, we are still focusing on these three points when developing RadChartView.
As our new charting solution developed and reached a certain set of features, we decided the put all our development efforts in RadChartView and plan only critical bugs for RadChart. As a result, we have not released new features for RadChart for some time now.
Now, regarding RadChartView and its missing support for 3D series - to be completely honest with you, 3D series support is not one of our major priorities, when developing our new charting solution. Its current priority is low compared to other feature requests for the control. The reason for this is that it brings no value into the data visualization element, it is not easier to compare values and to perceive data. I understand that some of our customers like 3D visualization better, but our current focus is on the missing data visualization features of RadChartView.
