           Is there a control for drill down in pie charts, i have seen your documentation but they are not clear enough to explain that feature.
    Can you give me an example of that feature using pie chart?
    Thank you.

    Hi Sarper,

      Before you can start using the drill down feature of RadChart, you'll need to implement Hierarchial View. This document will guide you through making sure your data is set up using ChartHierarchialViewDescriptor objects. After doing this, you can use this document as example code. It shows you how to layout your chart according to what level of data you are on.

      Even though the example is with a BarChart, the same process is used for a pie chart. For instance, you notice the chart in the example first shows the car manufacturers "ToyYoda" and "Marda". This is your first level of hierarchial data. Then when you drill down it goes to the car model level and displays "Coolla" and "Veso".

    I hope this clear it up for you, create the levels, then you can drill down.

    Good Luck,

    Hello Sarper,

    Yes, you can use the RadChart for drill-down. I have attached a simple app that demonstrates the use of Pie, Bar and Line series. The provided project is pretty much self-explanatory. Let us know if you have any concrete questions.

    Hello Peter Marchev and Lancelot,

       Firstly, i am grateful for your help and i will look at this example project. However, i will use the Prism Framework to Undo-Redo between charts. But there are 2 options now.
    Best regards
