使用 LiveCharts 在折线图中绘制垂直线

Draw vertical line in a line chart with LiveCharts

我正在开发一个 winform 应用程序以使用 LiveCharts 显示折线图。如何在某个 x 坐标处绘制垂直线?提前致谢。

我发现:

        cartesianChart.AxisX.Add(new Axis
        {
            //IsMerged = true,
            Sections = new SectionsCollection
            {
                new AxisSection
                {
                    Value = x_best,
                    Stroke = System.Windows.Media.Brushes.Red,
                    StrokeThickness = 3,
                    StrokeDashArray = new System.Windows.Media.DoubleCollection(new [] {10d})

                }
            }
        });
