Hello Manishkumar,

To be able to rotate the Series Items Labels you should retemplate the default Style and wrap the TextBlock around a  LayoutTransformControl.
The needed style together with the LayoutTransformControl is demonstrated below:

<Style x:Key="SeriesItemLabelStyle"
               TargetType="telerikCharting:SeriesItemLabel">
           <Setter Property="Padding" Value="2,0" />
           <Setter Property="IsHitTestVisible" Value="False"/>
           <Setter Property="ContentTemplate">
               <Setter.Value>
                   <DataTemplate>
                       <telerik:LayoutTransformControl>
                           <telerik:LayoutTransformControl.Content>
                               <TextBlock Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content }" TextAlignment="Center" />
                           </telerik:LayoutTransformControl.Content>
                           <telerik:LayoutTransformControl.LayoutTransform>
                               <RotateTransform Angle="-90" />
                           </telerik:LayoutTransformControl.LayoutTransform>
                       </telerik:LayoutTransformControl>
                   </DataTemplate>
               </Setter.Value>
           </Setter>
           <Setter Property="Template" >
               <Setter.Value>
                   <ControlTemplate TargetType="telerikCharting:SeriesItemLabel">
                       <Canvas x:Name="PART_MainContainer">
                           <Path Visibility="{TemplateBinding ConnectorVisibility}"
                             Style="{TemplateBinding ConnectorStyle}"
                             Stroke="{TemplateBinding Stroke}"
                             StrokeThickness="{TemplateBinding StrokeThickness}">
                               <Path.Data>
                                   <PathGeometry >
                                       <PathGeometry.Figures>
                                           <PathFigure x:Name="PART_Connector">
                                               <PathFigure.Segments>
                                                   <PolyLineSegment />
                                               </PathFigure.Segments>
                                           </PathFigure>
                                       </PathGeometry.Figures>
                                   </PathGeometry>
                               </Path.Data>
                           </Path>
                           <Border x:Name="PART_TextContainer"
                               Style="{TemplateBinding LabelStyle}"
                               BorderBrush="{TemplateBinding Stroke}"
                               Background="{TemplateBinding Fill}"
                               Width="{TemplateBinding Width}"
                               Height="{TemplateBinding Height}">
                               <ContentPresenter Margin="{TemplateBinding Padding}" />
                           </Border>
                       </Canvas>
                   </ControlTemplate>
               </Setter.Value>
           </Setter>
       </Style>

All the best,
