Add percentage sign to value

[Ivan]

This is the code for my PIE chart

<telerik:RadChart Grid.Row="1"
     telerik:Theming.Theme="Metro"
     HorizontalAlignment="Left"
     Padding="10"
     x:Name="pieChart"
     BorderThickness="0"
     Foreground="White"
     ItemsSource="{Binding PieData, Mode=TwoWay}"
     VerticalAlignment="Top">
     <telerik:RadChart.PaletteBrushes>
            <SolidColorBrush Color="{StaticResource QMFirstColor}"/>
            <SolidColorBrush Color="{StaticResource QMSecondColor}"/>
      </telerik:RadChart.PaletteBrushes>
      <telerik:RadChart.SeriesMappings>
             <telerik:SeriesMapping LegendLabel="Legend">
                 <telerik:SeriesMapping.SeriesDefinition>
                        <telerik:PieSeriesDefinition AxisName="Evals" ShowItemLabels="True" />
                    </telerik:SeriesMapping.SeriesDefinition>
                    <telerik:ItemMapping FieldName="Total" DataPointMember="YValue" />
                    <telerik:ItemMapping FieldName="Label" DataPointMember="LegendLabel" />
                </telerik:SeriesMapping>
            </telerik:RadChart.SeriesMappings>


            <telerik:RadChart.DefaultView>
                <telerik:ChartDefaultView ChartLegendPosition="Bottom">
                    <telerik:ChartDefaultView.ChartArea>
                        <telerik:ChartArea LabelFormatBehavior="HumanReadable"
                                           LegendName="legend"
                                           FontFamily="{StaticResource DefaultLabelStyle}"
                                           FontSize="13.333">
                            <telerik:ChartArea.AxisX>
                                <telerik:AxisX AxisLabelsVisibility="Visible" />
                            </telerik:ChartArea.AxisX>
                            <telerik:ChartArea.AxisY>
                                <telerik:AxisY AxisName="Evals" Title="Monthly Totals" />
                            </telerik:ChartArea.AxisY>
                        </telerik:ChartArea>
                    </telerik:ChartDefaultView.ChartArea>
                    <telerik:ChartDefaultView.ChartLegend>
                        <telerik:ChartLegend Header="{Binding ElementName=ChartLegend1,Path=Tag,Mode=TwoWay, Converter={StaticResource LabelConverter}}"
                                             x:Name="legend"
                                             LegendItemMarkerShape="Circle"
                                             Visibility="Visible"
                                             Padding="0" />
                    </telerik:ChartDefaultView.ChartLegend>
                </telerik:ChartDefaultView>
            </telerik:RadChart.DefaultView>
        </telerik:RadChart>

How can I add the percentage sign to the value on the chart view... I have tried out " DefaultLabelValue="#Y%" but I don't know where to put it.

Edit... found the answer... Have to add ItemLabelFormat="#%{P2}" into the telerik:PieSeriesDefinition
