3 、
在Veiw中绑定
xmlns:lvc=“using:LiveChartsCore.SkiaSharpView.WinUI”
<lvc:PieChart
Series=“{Binding SeriesCartesian}”
>
在ViewModel中 ：注意msyh.ttc是从电脑系统中的字体下载下来的微软雅黑字体，使用它用来支持中文字体，把它放入生成的Debug文件夹下
void ShowCartesianChart()
{
var typeface = SKTypeface.FromFile(“msyh.ttc”);
TextPaint = new SolidColorPaint()
{
Color = SKColors.DarkSlateGray,
//SKTypeface = SKFontManager.Default.MatchCharacter(‘汉’)
SKTypeface = typeface,

    };
    SeriesCartesian = new ObservableCollection<ISeries> {
           new RowSeries<ObservableValue>
          {
            Values = new[] { new ObservableValue(43)},
            Name="张三",

            DataLabelsPaint=TextPaint,

            DataLabelsPosition=DataLabelsPosition.Middle,
            DataLabelsFormatter=value=>$"{value.Context.Series.Name}{value.Coordinate.PrimaryValue}"


           },
              new RowSeries<ObservableValue>
          {
          Values = new[] { new ObservableValue(23)},
          DataLabelsPaint=TextPaint,

            DataLabelsPosition=DataLabelsPosition.Middle,
            DataLabelsFormatter=value=>"李四"

           },
            };
            var xAxis = new Axis
    {
        Labeler = Labelers.Default,

        //Labels = new[] { "张三", "李四", "王五", "赵六", "测试" },
        //Name = "XXX",
        //LabelsPaint = TextPaint,
        //CrosshairLabelsPaint = TextPaint,
        //NamePaint = TextPaint,


    };


    XCartesianAxes = new List<Axis> { xAxis };

    //YCartesianAxes = new List<Axis> { new Axis { Labeler = Labelers.Currency, LabelsPaint = TextPaint } };
    YCartesianAxes = new List<Axis> { new Axis { IsVisible = false } };
    }
