this.PieSeries = new ObservableCollection<RevenueProperties>()
            {
                new RevenueProperties() { Items = "iTunes", Revenue = 6},
                new RevenueProperties() { Items = "Others", Revenue = 4},
                new RevenueProperties() { Items = "iPhone", Revenue = 48},
                new RevenueProperties() { Items = "iPad", Revenue = 21},
                new RevenueProperties() { Items = "Mac", Revenue = 18},
                new RevenueProperties() { Items = "iPod", Revenue = 2},
            };
        this.DataContext = this;
<Window.Resources>
        <DataTemplate x:Key="labelTemplate">
            <Grid>
                <TextBlock Text="{Binding Items}"/>
                <TextBlock Text="{Binding Revenue}"/>
            </Grid>
        </DataTemplate>
    </Window.Resources>
<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}"/>
                    </Syncfusion:PieSeries.AdornmentsInfo>
</Chart:PieSeries>

我尝试上面的程序文本块值不绑定任何东西，当我运行这个程序时得到空饼图。请帮助解决此绑定问题

数据绑定到文本块

您是否在类后面的窗口代码上实现了 INotiFyProperty 接口？如果没有，请实现通知...，然后从 PieSeries、Items 和 Revenue 字段的 setter 调用 OnPropertyChanged 方法。
