Chart pie: series' labels

[Ilaria]

Hello!
I've got a chart with two pie series. I need to know if it's possible to show a label for each series over each pie.

Thanks a lot.

Hi Ilaria,

By default Series show the YValues of the Chart as Series Items labels as shown in our demo. You can use the DataLabelsColumn property of the Series to bind the custom Label for each Slice.

Hello Evgenia,
what Ilaria means is if it's possible to have something as I've attached in the image below in the PIE definition without having to add two textbox over it the pies

Thanks

Hi Paolo,

Thanks for the image attached and for the explanation. I can suggest you two ways to achieve what you need. It's up to you to decide which one to use:

1. Use the Chart Legend and set custom Name for each ChartSeries (in your case each Pie). This way the Name will be displayed as Chart Legend Item like this:

<telerik:RadChart ID="RadChart1" runat="server">
          <Series>
              <telerik:ChartSeries Name="Pie 1" Type="Pie">
              </telerik:ChartSeries>
              <telerik:ChartSeries Name="Pie 2" Type="Pie">
              </telerik:ChartSeries>
          </Series>
      </telerik:RadChart>

2. Use the Chart Title and set the text for the two Pies there (see the attached image showing the result):
 

<telerik:RadChart ID="RadChart1" runat="server">
            <Series>
                <telerik:ChartSeries Name="Pie 1" Type="Pie">
                </telerik:ChartSeries>
                <telerik:ChartSeries Name="Pie 2" Type="Pie">
                </telerik:ChartSeries>
            </Series>
            <ChartTitle TextBlock-Text="Pie 1                 Pie 2" />
        </telerik:RadChart>

Kind regards,

I have accomplished adding multiple labels (both x and y axis) to a pie chart using the following code behind.  In this example, my table has two columns named Status and Records.  See attached.  Hope this helps...

 

 

Private Sub RadChart59_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Charting.ChartItemDataBoundEventArgs) Handles RadChart59.ItemDataBound

        Dim item As Telerik.Charting.ChartSeriesItem = e.SeriesItem

        Dim dataItem As Data.DataRowView = CType(e.DataItem, Data.DataRowView)

        item.Label.TextBlock.Text = RTrim(dataItem("Status").ToString) + " - " + RTrim((dataItem("Records").ToString))

End Sub
