            {
                new RevenueProperties() { Items = "iTunes", Revenue = 6},
                new RevenueProperties() { Items = "Others", Revenue = 4},
                new RevenueProperties() { Items = "iPhone", Revenue = 48},

                new RevenueProperties() { Items = "iPod", Revenue = 2},
            };

<Window.Resources>
        <DataTemplate x:Key="labelTemplate">
            <Grid>
                <TextBlock Text="{Binding Items}"/>
                <TextBlock Text="{Binding Revenue}"/>
            </Grid>

<Chart:PieSeries ExplodeIndex="0" ExplodeRadius="15" ExplodeAll="False" Palette="Custom" LabelPosition="Inside"
                                      ItemsSource="{Binding PieSeries}" XBindingPath="Items" YBindingPath="Revenue">

                    <Chart:PieSeries.AdornmentsInfo>
                        <Chart:ChartAdornmentInfo FontSize="9" ShowLabel="True" SegmentLabelContent="Percentage"
                                                       ShowConnectorLine="True" LabelTemplate="{StaticResource labelTemplate}"/>

Have you implemented INotiFyProperty interface on your window code behind class? if not, implement Inotify... on your window and call the OnPropertyChanged method from the setter of PieSeries, Items and Revenue fields.

Check below link on detailed explanation of INotify... interface: http://www.codeproject.com/Articles/41817/Implementing-INotifyPropertyChanged
