Hi

    I am have attached a jpeg of two pie charts. 1st I got from google and the 2nd one created using Telerik RadChart for Silverlight. Is it possible to have the labels(not on top of the pie) seperately with a arrow point to the pie like it is in the 1st chart.

Thanks
Saran

Hi Saravanan Thiruchabai,

You can achieve similar look using the new labels API we added to the last version of the control. Here is a sample code:
PieSeriesDefinition def = new PieSeriesDefinition();
def.RadiusFactor = 0.5;
def.LabelSettings.ShowConnectors = true;
def.LabelSettings.SpiderModeEnabled = true;

Hi,
I take it that you cant do this in XAML at the moment?

Hello Marcus,

Here is how you can set up the same code in xaml:
<telerik:RadChart x:Name="RadChart1">
    <telerik:RadChart.DefaultSeriesDefinition>
        <telerikCharting:PieSeriesDefinition RadiusFactor="0.5">
            <telerikCharting:PieSeriesDefinition.LabelSettings>
                <telerikCharting:RadialLabelSettings ShowConnectors="True" SpiderModeEnabled="True"/>
            </telerikCharting:PieSeriesDefinition.LabelSettings>
        </telerikCharting:PieSeriesDefinition>
    </telerik:RadChart.DefaultSeriesDefinition>
</telerik:RadChart>


Kind regards,

Is it possible to do the same with 3D PieChart?
I dont see a property RadiusFactor for Pie3dSeriesDefinition.

Thanks

I tried using LabelOffSet, ChartArea.SmartLabelsEnabled = true,

assetAllocationChart.DefaultSeriesDefinition.SeriesItemLabelStyle, nothing seems to be working with related to 3dPieChart Labels. Wont these work for 3d Pie Chart?

Find the attached 3d Pie Chart. The labels are overlapping eachother. I tried setting the LabeOffSet it didn't work.
I tried changing the background color of the label to be transparent and reducing the fontsize using assetAllocationChart.DefaultSeriesDefinition.SeriesItemLabelStyle. Nothing seems to work.

Thanks

Hi Velin,

 

    Since the labels were overlapping I made the Labels hidden by setting ShowItemLabels = false and I tried the following code to show tooltips in 3D Pie chart. It didn't show any tooltip. Does this functionality work in 3D Pie chart?
Pie3DSeriesDefinition assetPS = new Pie3DSeriesDefinition();

 

assetPS.ShowItemToolTips =

true;

 

assetPS.ItemToolTipFormat =

"#LegendLabel";

 

 

Thanks
Saran

Hello Saravanan Thiruchabai,

Tooltips are not supported in the 3D Silverlight charts either. If you need these features I would suggest you to stick with the 2D pie chart.

Please, accept our apologies for this inconvenience.
