Answer 1

由于您要为TargetType="chart:ChartBase"定义样式，而您使用的是chart:PieChart，因此会出现此问题。

请为chart:PieChart定义样式，如：

StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary >
        <Style x:Key="MinimalChartStyle" TargetType="chart:PieChart">
            <Setter Property="Width" Value="500"/>
            <Setter Property="Height" Value="500"/>
        </Style>
    </ResourceDictionary>
</Application.Resources>
