    hi  all,

    The  x-axis labels of  chart are  reapeted as 30.12  when  timebar  is  in  yearly view  : 

      when  i select  few  monthly view ( PFA : Monthlyview.jpg) the  x-axis  lables are coming  fine  but  when  i select the  Yearly view( PFA : Yearly.jpg) the x-asis  labels are repeated.

    Please find the xaml code  below  :

    <Grid x:Name="LayoutRoot"
              DataContext="{StaticResource xSalesViewModel}"
                <RowDefinition Height="Auto" />
                <RowDefinition Height="150" />
                <RowDefinition />
                <ColumnDefinition />
                <ColumnDefinition />
            <local:SalesViewModel x:Name="xSalesViewModel" />
            <TextBlock FontFamily="Portable User Interface"
                       Margin="5" />
            <telerik:RadTimeBar x:Name="xRadTimeBar"
                                     PeriodStart="1-Jan-2011" PeriodEnd="1-Jan-2012" 
                                    VisiblePeriodStart="1-Jan-2011" VisiblePeriodEnd="1-Jan-2012" 
                                    SelectionStart="1-Aug-2011" SelectionEnd="30-Sep-2011" 
                    <telerik:YearInterval />
                    <telerik:MonthInterval />
                    <telerik:WeekInterval />
                    <telerik:DayInterval />
                    <telerik:HourInterval />                
                <telerik:RadAreaSparkline ItemsSource="{Binding SalesData}"
                                          Margin="0,8" />
            <telerik:RadChart x:Name="xRadChart"
                              TimeBar="{Binding ElementName=xRadTimeBar}"
                              ItemsSource="{Binding SalesData}"
    Grid.ColumnSpan="2"                          Grid.Row="2"
                            <telerik:AreaSeriesDefinition />
                            <telerik:ItemMapping FieldName="salestotal"
                                                 DataPointMember="YValue" />
                            <telerik:ItemMapping FieldName="datadate"
                                                 DataPointMember="XCategory" />
                            <telerik:ChartDefaultView.ChartLegend >
                                <telerik:ChartLegend Name="legend" Visibility="Collapsed" />

    Hello Rajesh,
    This can happen, in case the data entries, visualized by the chart control, differ by less than a day. You can check this, by removing the DefaultLabelFormat setting for the x-axis.

    In case you need additional help with that, please open a formal support ticket and send a simple running project that demonstrates the problem, together with detailed information on the steps I need to follow, in order to reproduce it.

    Best wishes,
    the Telerik team
