試圖做一個不斷運行的線圖

Question

我有一個運行良好的程序，它重複使用不同的自變量值的一系列公式。我現在想在循環的每次迭代之後繪製一個計算圖。這是我到目前爲止有：

public static void main(String[] args) { 


    JFrame window=new JFrame(); 
    window.setTitle("Try"); 
    window.setSize(600, 400); 
    window.setLayout(new BorderLayout()); 
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    window.setVisible(true); 

    XYSeries series = new XYSeries("graph"); 
    XYSeriesCollection dataset= new XYSeriesCollection(series); 

    ... 

我最大的問題是我怎麼把我的數據，並生成一個數據集，然後我怎麼做圖表更新循環的每次迭代後？我已經導入了JFreeChart類和一些swing。任何和所有的見解將不勝感激。

所以我在一段時間後想到了這一點。訣竅是在循環內部設置可見。但是現在，JFrame隨着每次迭代重新繪製。我不知道是否有辦法保持幀不變。如果有人知道，我會很感激幫助。
