我曾尝试在 vb.net 项目中实现 LiveCharts，但没有成功。尝试搜索互联网，但不幸的是没有找到示例代码。我的代码中可能有什么问题？示例代码

    Private Sub InitializeChart()
    Dim labelPoint As Func(Of ChartPoint, String) = Function(chartPoint) String.Format("{0} ({1:P})", chartPoint.Y, chartPoint.Y, chartPoint.Participation)
    'pieChartMain = New LiveCharts.WinForms.PieChart
    Dim seriesCollection As SeriesCollection = New SeriesCollection
    Dim pieSeries1 As PieSeries = New PieSeries
    Dim pieSeries2 As PieSeries = New PieSeries
    pieSeries1.Title = "MALE"
    pieSeries1.Values = New ChartValues(Of Double) From {3}
    pieSeries1.PushOut = 15
    pieSeries1.DataLabels = True
    pieSeries1.LabelPoint = labelPoint

    pieSeries2.Title = "FEMALE"
    pieSeries2.Values = New ChartValues(Of Double) From {6}
    pieSeries2.DataLabels = True
    pieSeries2.LabelPoint = labelPoint

    seriesCollection.Add(pieSeries1)
    seriesCollection.Add(pieSeries2)
    pieChartMain.Series.Add(seriesCollection)

    pieChartMain.LegendLocation = LegendLocation.Bottom

    pieChartMain.Show()
End Sub

我认为该示例需要更多信息才能有人尝试帮助...

PIE 控件名称是什么？

你在导入库吗？

Imports LiveCharts.WinForms
Imports LiveCharts.Wpf
Imports LiveCharts

在最后一个 PieChart 命令之后，尝试强制重绘。例如，在 Gauge 控件中，如果利用：

Gauge.resumelayout

所以，尝试 REFRESH 和 RESUMELAYOUT 控制
