C＃Zedgraph，图表跳跃

Question

我正在使用C＃和ZedGraph库在时间和温度之间绘制图形。输入值从文本文件中读取。预计图形曲线会有所进展，但在曲线不是渐进的情况下，曲线的前后移动与点无关。但是这些点在图中正确绘制。

这是我的代码..

  private void Form2_Load(object sender, EventArgs e)
  {
    GraphPane myPane = Gcontrol.GraphPane;

    // Set the title and axis labels
    myPane.Title.Text = "Date Time Chart";
    myPane.XAxis.Title.Text = "TimeFrame";
    myPane.YAxis.Title.Text = "Temperature";

    //List to hold Points to be plotted
    PointPairList pList = new PointPairList();

    SampleData sd = new SampleData();
    sd.getSampleData();


    for (int i = 0; i < sd.x.Count; i++)
    {
        pList.Add(sd.x[i],sd.y[i]);
    }

    LineItem curve = myPane.AddCurve("Points", pList, Color.Black, SymbolType.Diamond);
    curve.Line.IsSmooth = true;
    myPane.XAxis.Type = AxisType.Date;
    myPane.XAxis.Scale.FontSpec.Angle = 65;
    myPane.XAxis.Scale.MajorStep = 1;
    myPane.XAxis.Scale.MajorUnit = DateUnit.Hour;
    myPane.XAxis.Scale.MinorUnit = DateUnit.Hour;
    myPane.XAxis.Scale.Format = "dd-MMM-yy HH:MM";
    Gcontrol.AxisChange();

}

SampleDataClass：

class SampleData
{
    public List<double> x = new List<double>();
    public List<double> y = new List<double>();

    public void getSampleData()
    {            

        string[] lines = System.IO.File.ReadAllLines("input.txt");
        foreach (string line in lines)
        {
          x.Add(new XDate(Convert.ToDateTime(line.Split(',')[0].Trim())));                 
          y.Add(Convert.ToDouble(line.Split(',')[4].Trim()));

        }

    }
}

input.txt文件内容：第1列包含时间，第5列包含温度

Answer 1

终于找到了，我不得不设置

curve.Line.IsSmooth = false; 

（或）完全删除该行

curve.Line.IsSmooth = true;
