Hi,
I am using Telerik RadControls for ASP.NET Ajax, ver 2.0.50727. I am programatically creating a RadChart(Pie) and databinding the same to a database object. Since there are many sections in the chart, Labels are overlapping. I set the below properties to solve the overlapping issue as mentioned in some of the threads

this._radChart.Series[0].Appearance.ShowLabelConnectors = true;
this._radChart.Series[0].Appearance.LabelAppearance.Distance += 2;

Though I see significant improvement in charts having many closer sections near the center of the chart, charts with smaller sections towards the top and bottom are still overlapping because of the connectors. Please see the attached chart image for the issue highlighted in red-rounded rectangle.

Moreover, If there are too many close sections, I want to Zoom particular section of Piechart to see the labels clearly. When I set

this._radChart.ClientSettings.EnableZoom = true, am getting the error "Zooming & scrolling can't be enabled for PieChart series type"

How do I enable Zooming for a particular section in the pie chart ?
How to avoid the overlapping issue caused by the connectors towards the top and bottom portion of charts?

Please help me.Its urgent.

Regards,
Priya

Hello Anupriya Govindarajan,

Zooming and scrolling is not supported for pie series. We are sorry for the inconvenience.

Hi Anupriya Govindarajan,

There is no easy way to do this. I can suggest trying to increase the size of the control or not using connectors and generally going through all the different options check which one looks OK. Also you may still consider turning those labels off and rely on the legend only.

All the best,
