Hi Ramya,

Could you please be more specific on what do you want to achieve? A sample image demonstrating how would you like your chart to look like will be very helpful for us to guide you more properly.

Hi Evgenia,
I just found that marked zones are not visible in Pie. I want to add a bubble mark on a pie as shown in the attched image. Is this possible?? If so, how ?

Hi Evgenia,
I am trying to add the image by calculating the end of the pie chart. I want the radius of the pie and i got it from Actual width of the pie slice item on item click. However, I am not getting this pie Item on load. Is there a way to get the pie Item on load of DefaultView.ChartArea??

Hi Ramya,

For each Series Mapping there is a data series generated in the RadChart.DefaultView.ChartArea.DataSeries collection. However you'll need to wire to the DataBound event of the Chart for your collection not to be empty.
