JFreeChart：如何繪製一個OHLC圖表的移動平均線

Question

我想覆蓋一個移動平均線的OHLC圖表，但它似乎不起作用。

我提供的代碼的兩個關鍵功能：

private static OHLCDataset createPriceDataset(String filename) 
{ 
    OHLCSeries s1 = new OHLCSeries(filename); 

    try { 
     BufferedReader in = new BufferedReader(new FileReader(filename)); 
     DateFormat df = new SimpleDateFormat("yyyyMMdd"); 
     String inputLine; 
     in.readLine(); 
     while ((inputLine = in.readLine()) != null) { 
      StringTokenizer st = new StringTokenizer(inputLine, ","); 
      Date date  = df.parse(st.nextToken()); 
      double open  = Double.parseDouble(st.nextToken()); 
      double high  = Double.parseDouble(st.nextToken()); 
      double low  = Double.parseDouble(st.nextToken()); 
      double close = Double.parseDouble(st.nextToken()); 
      double volume = Double.parseDouble(st.nextToken()); 
      //double adjClose = Double.parseDouble(st.nextToken()); 
      s1.add(new Day(date), open, high, low, close); 
     } 
     in.close(); 
    } 
    catch (Exception e) { 
     e.printStackTrace(); 
    } 

    OHLCSeriesCollection dataset = new OHLCSeriesCollection(); 
    dataset.addSeries(s1); 

    return dataset; 
} 



private static JFreeChart createCombinedChart() 
{ 
    OHLCDataset data1 = createPriceDataset(filename); 

    XYItemRenderer renderer1 = new HighLowRenderer(); 
    renderer1.setBaseToolTipGenerator(new StandardXYToolTipGenerator(StandardXYToolTipGenerator.DEFAULT_TOOL_TIP_FORMAT, new SimpleDateFormat("d-MMM-yyyy"), new DecimalFormat("0.00"))); 
    renderer1.setSeriesPaint(0, Color.blue); 
    DateAxis domainAxis = new DateAxis("Date"); 
    NumberAxis rangeAxis = new NumberAxis("Price"); 
    rangeAxis.setNumberFormatOverride(new DecimalFormat("$0.00")); 
    rangeAxis.setAutoRange(true); 
    rangeAxis.setAutoRangeIncludesZero(false); 
    XYPlot plot1 = new XYPlot(data1, domainAxis, rangeAxis, renderer1); 
    plot1.setBackgroundPaint(Color.lightGray); 
    plot1.setDomainGridlinePaint(Color.white); 
    plot1.setRangeGridlinePaint(Color.white); 
    plot1.setRangePannable(true); 

    //Overlay the Long-Term Trend Indicator 
    XYDataset dataset3 = MovingAverage.createMovingAverage(data1, "LT", 49.0, 49.0); 
    plot1.setDataset(1, dataset3); 
    plot1.setRenderer(1, new StandardXYItemRenderer()); 

    //add a second dataset (volume) and renderer 
    IntervalXYDataset data2 = createVolumeDataset(filename); 
    XYBarRenderer renderer2 = new XYBarRenderer(); 
    renderer2.setDrawBarOutline(false); 
    renderer2.setBaseToolTipGenerator(new StandardXYToolTipGenerator(StandardXYToolTipGenerator.DEFAULT_TOOL_TIP_FORMAT, new SimpleDateFormat("d-MMM-yyyy"), new DecimalFormat("0,000.00"))); 
    renderer2.setSeriesPaint(0, Color.red); 

    XYPlot plot2 = new XYPlot(data2, null, new NumberAxis("Volume"), renderer2); 
    plot2.setBackgroundPaint(Color.lightGray); 
    plot2.setDomainGridlinePaint(Color.white); 
    plot2.setRangeGridlinePaint(Color.white); 

    CombinedDomainXYPlot cplot = new CombinedDomainXYPlot(domainAxis); 
    cplot.add(plot1, 3); 
    cplot.add(plot2, 2); 
    cplot.setGap(8.0); 
    cplot.setDomainGridlinePaint(Color.white); 
    cplot.setDomainGridlinesVisible(true); 
    cplot.setDomainPannable(true); 


    //return the new combined chart 
    JFreeChart chart = new JFreeChart("Sun Microsystems (SUNW)", JFreeChart.DEFAULT_TITLE_FONT, cplot, false); 

    ChartUtilities.applyCurrentTheme(chart); 
    renderer2.setShadowVisible(false); 
    renderer2.setBarPainter(new StandardXYBarPainter()); 

    return chart; 
} 

任何想法？

謝謝。

我已經添加了下面的代碼，它似乎工作。 如果有人不同意這個解決方案只是讓我知道。 這裏有雲：

public class PriceVolumeChart2 extends ApplicationFrame{ 

final static String filename = "A.txt"; 
*static TimeSeries t1 = new TimeSeries("49-day moving average");* 

/** 
* Default constructor 
*/ 
public PriceVolumeChart2(String title) 
{ 
    super(title); 
    JPanel panel = createDemoPanel(); 
    panel.setPreferredSize(new Dimension(500, 270)); 
    setContentPane(panel); 
} 

//create price dataset 
//hard-coded here 
private static OHLCDataset createPriceDataset(String filename) 
{ 
    //the following data is taken from http://finance.yahoo.com/ 
    //for demo purposes... 

    OHLCSeries s1 = new OHLCSeries(filename); 

    try { 
     BufferedReader in = new BufferedReader(new FileReader(filename)); 
     DateFormat df = new SimpleDateFormat("yyyyMMdd"); 
     String inputLine; 
     in.readLine(); 
     while ((inputLine = in.readLine()) != null) { 
      StringTokenizer st = new StringTokenizer(inputLine, ","); 
      Date date  = df.parse(st.nextToken()); 
      double open  = Double.parseDouble(st.nextToken()); 
      double high  = Double.parseDouble(st.nextToken()); 
      double low  = Double.parseDouble(st.nextToken()); 
      double close = Double.parseDouble(st.nextToken()); 
      double volume = Double.parseDouble(st.nextToken()); 
      //double adjClose = Double.parseDouble(st.nextToken()); 
      s1.add(new Day(date), open, high, low, close);

     }

    OHLCSeriesCollection dataset = new OHLCSeriesCollection();
