WPF编程，Live Charts使用说明（35）——不连续曲线（间断线）

当您不知道直线系列中的值时，请 使用double.NaN，该点将是不确定的，绘制直线系列时将被忽略。

后台：

using System.Windows.Controls;
using LiveCharts;
using LiveCharts.Wpf;
 
namespace Wpf.CartesianChart.Missing_Line_Points
{
    public partial class MissingPointsExample : UserControl
    {
        public MissingPointsExample()
        {
            InitializeComponent();
 
            Series = new SeriesCollection
            {
                new LineSeries
                {
                    Values = new ChartValues<double>
                    {
                        4,
                        5,
                        7,
                        8,
                        double.NaN,
                        5,
                        2,
                        8,
                        double.NaN,
                        6,
                        2
                    }
                }
            };
 
            DataContext = this;
        }
 
        public SeriesCollection Series { get; set; }
 
    }
}
