我正在使用 dotnet 高图表和 asp.net mvc3。我在向样条图添加多个系列时遇到问题。

这段代码基本上每秒更新一次图表。

这适用于一个数据系列。但我需要添加多个数据系列。

请帮助我为此代码添加多个系列。

public ActionResult SplineUpdateEachSecond()
{
     List<object> points = new List<object>(20);
     DateTime now = DateTime.Now;
     Random rand = new Random();
     for (int i = -19; i <= 0; i++)
          points.Add(new { X = now.AddSeconds(i), Y = rand.NextDouble() });

     Highcharts chart = new Highcharts("chart")

        return View(chart);

这里有例子。

假设，有一个类返回如下系列：

public class ChartsData
{
     //public static Series Hestavollane
     //public static Series Voll 
}

第一个系列：

public static Series Hestavollane = new Series
                                    {
                                        Name = "Hestavollane",
                                        Data = new Data(new object[]
                                                       {
                                                            4.3, 5.1, 4.3, 5.2, 5.4, 4.7, 3.5, 4.1, 5.6, 7.4, 6.9, 7.1,
                                                            7.9, 7.9, 7.5, 6.7, 7.7, 7.7, 7.4, 7.0, 7.1, 5.8, 5.9, 7.4,
                                                            8.2, 8.5, 9.4, 8.1, 10.9, 10.4, 10.9, 12.4, 12.1, 9.5, 7.5,
                                                            7.1, 7.5, 8.1, 6.8, 3.4, 2.1, 1.9, 2.8, 2.9, 1.3, 4.4, 4.2,
                                                            3.0, 3.0
                                                       })
                                    };

第二系列：

public static Series Voll = new Series
                            {
                                Name = "Voll",
                                Data = new Data(new object[]
                                                {
                                                    0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.1, 0.0, 0.3, 0.0,
                                                    0.0, 0.4, 0.0, 0.1, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0,
                                                    0.0, 0.6, 1.2, 1.7, 0.7, 2.9, 4.1, 2.6, 3.7, 3.9, 1.7, 2.3,
                                                    3.0, 3.3, 4.8, 5.0, 4.8, 5.0, 3.2, 2.0, 0.9, 0.4, 0.3, 0.5, 0.4
                                                })
                            };

应用于图表

.SetSeries(new[] { ChartsData.Hestavollane, ChartsData.Voll })
