Question

我试图在vb.net项目中实现LiveCharts但不成功。尝试搜索互联网，但幸运的是没有找到示例代码。我的代码中可能存在哪些问题？sample code

    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

我认为样本需要更多信息给某人尝试帮助...

什么是PIE控件名称？

您是在进口图书馆吗？

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，如果使用：

，我会获得成功

Gauge.resumelayout

因此，尝试REFRESH以及控件上的RESUMELAYOUT

LiveCharts没有在vb.net中显示
