我使用C#和ZedGraph庫在時間和溫度之間繪製圖形。輸入值從文本文件中讀取。圖表曲線預計會有所進展,但曲線不是漸進的,它將與點不相關,而是在圖表中正確繪製點。C#Zedgraph,圖形跳轉

這裏是我的代碼..

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的文件的內容:第1欄包含時間和第5列包含溫度

你嘗試過調試和觀察數據,你讀過之後,確保你已經正確解釋了一切?我看到例如你在文件中有AM/PM,這是正確的讀取和解析? –

@Karlsen。是的,我已經把調試點和檢查時間,他們正在閱讀和解釋正確。我甚至發現圖形點完全被繪製出來。它只是不是逐步移動的曲線。 – jaycyborg

終於找到了,我必須設置

curve.Line.IsSmooth = false; 

(或)徹底清除線

curve.Line.IsSmooth = true;
