我在 WPF 中使用 Telerik（RadPieChart）。如何在切片之間添加空間？這是我目前擁有的：這就是我希望餅圖在切片之間有空格的樣子：這是我的源代碼：private DoughnutSeries CreateDognutSerie(KeyValuePair<ChartSerie, List<ChartDataPoint>> chartSerie, int index, int count) { double spaceBetweenSperies = 0.0; if (count > 1 && index != count - 1) { spaceBetweenSperies = 0.007; } var doughnutSerie = new DoughnutSeries() { ShowLabels = true, //LabelConnectorsSettings = new ChartSeriesLabelConnectorsSettings() //{ //}, InnerRadiusFactor = index / (double)count, RadiusFactor = ((index + 1) / (double)count) - spaceBetweenSperies, //LegendSettings = new DataPointLegendSettings() //{ //}, //SeriesAnimation = new PieChartAngleRangeAnimation() //{ // InitialStartAngle = -90, // InitialSweepAngle = 180, // Duration = new TimeSpan(0, 0, 0, 0, 800), //} }; foreach (ChartDataPoint serie in chartSerie.Value) { doughnutSerie.DataPoints.Add(new PieDataPoint() { Label = serie.XPoint.Label, Value = Math.Abs((double?)serie.Value ?? 0), }); } return doughnutSerie; }

使用中的OffsetFromCenter屬性PieDataPoint。類似的東西OffsetFromCenter = 0.015應(yīng)該類似于上圖。
public MainWindow()
{
InitializeComponent();
var data = new Dictionary<string, double>
{
{ "January", 5 },
{ "February", 3 },
{ "March", 5 },
{ "April", 7 },
{ "May", 2 },
{ "June", 11 },
{ "July", 11 },
{ "August", 11 },
{ "September", 11 },
{ "October", 11 },
{ "November", 11 },
{ "December", 12 },
};
var series = CreateDougnutSeries(data);
var pie = new RadPieChart { Palette = ChartPalettes.Fluent };
pie.Series.Add(series);
mainGrid.Children.Add(pie);
}
private DoughnutSeries CreateDougnutSeries(Dictionary<string, double> data)
{
var doughnutSeries = new DoughnutSeries
{
ShowLabels = true,
InnerRadiusFactor = 0,
RadiusFactor = 1
};
foreach (var point in data)
{
doughnutSeries.DataPoints.Add(new PieDataPoint()
{
Label = point.Key,
Value = point.Value,
OffsetFromCenter = 0.015
});
}
return doughnutSeries;
}
增加OffsetFromCenter說0.1會渲染更粗的線條：
