how can i show multiple label on pie chart?

[shunman]

Is there a way to showing extra label on Pie Chart?
I'm looking for solution for this woe.
I wish to make a pie chart like  attaching image.

From the Attaching image, the outside labels indicate "MonthCount" fields from datasource
and Inside labels indecate "Month" field

here is my datasource and definition pie chart control on aspx. thank you.

Dim dataTablePieData As New DataTable()
        dataTablePieData = New DataTable()
        dataTablePieData.Columns.Add("Year")
        dataTablePieData.Columns.Add("Month")
        dataTablePieData.Columns.Add("MonthCount")

        dataTablePieData.Rows.Add(New Object() {"2009", "1", "20"})
        dataTablePieData.Rows.Add(New Object() {"2009", "2", "20"})
        dataTablePieData.Rows.Add(New Object() {"2009", "3", "70"})
        dataTablePieData.Rows.Add(New Object() {"2009", "4", "143"})
        dataTablePieData.Rows.Add(New Object() {"2009", "5", "210"})
        dataTablePieData.Rows.Add(New Object() {"2009", "6", "250"})
        dataTablePieData.Rows.Add(New Object() {"2009", "7", "252"})
        dataTablePieData.Rows.Add(New Object() {"2009", "8", "396"})
        dataTablePieData.Rows.Add(New Object() {"2009", "9", "406"})
        dataTablePieData.Rows.Add(New Object() {"2009", "10", "470"})
        dataTablePieData.Rows.Add(New Object() {"2009", "11", "472"})
        dataTablePieData.Rows.Add(New Object() {"2009", "12", "431"})

        GetPieData = dataTablePieData

Hello Shunman,

Currently you can't have more than one label for RadChart. Why don't you show both of these in one and the same Label, separated by "-" for example. For the purpose you may wire to the ItemDataBound event and set the two fields as item.Label like this:

Telerik.Charting.ChartSeriesItem item = e.SeriesItem;

    Data.DataRowView dataItem = (Data.DataRowView)e.DataItem;

    item.Label.TextBlock.Text = dataItem("Month").ToString() + " - " + dataItem("MonthCount").ToString();
