我需要显示一个PieChart,我目前正在使用Modern UI(Metro)图表.我确实复制了文档中的代码,问题是我总是在屏幕上有边框和标题但没有图表.

XAML

<UserControl x:Class="Projet.Recources0.Statistique.Ad_Aj"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:mui="http://firstfloorsoftware.com/ModernUI"
         xmlns:controls="http://metro.mahapps.com/winfx/xaml/controls"
         xmlns:chart="clr-namespace:De.TorstenMandelkow.MetroChart;assembly=De.TorstenMandelkow.MetroChart"
         mc:Ignorable="d" d:DesignWidth="1000" Height="670">

<UserControl.Resources>
    <Style x:Key="MinimalChartStyle" TargetType="{x:Type chart:ChartBase}">
        <Setter Property="Width" Value="500"/>
        <Setter Property="Height" Value="500"/>            
    </Style>
</UserControl.Resources>
<Grid >
    <chart:PieChart
    Style="{StaticResource MinimalChartStyle}"
    ChartTitle="Minimal Pie Chart"
    ChartSubTitle="Chart with fixed width and height"
    SelectedItem="{Binding Path=SelectedItem, Mode=TwoWay}" >
        <chart:PieChart.Series>
            <chart:ChartSeries
            SeriesTitle="Errors"
            DisplayMember="Category"
            ValueMember="Number"
            ItemsSource="{Binding Path=Errors}" />
        </chart:PieChart.Series>
    </chart:PieChart>
</Grid>
