achartengine多条线路在一个linegraph

我试图让两行根据该视频显示在图： http://www.youtube.com/watch?v=5DGldVzC-bU achartengine多条线路在一个linegraph

我的代码：

public class LineGraph { 
    public Intent getIntent(Context context){ 


     int[] x = {1,2,3,4,5,6,7,8,9,10}; 
     int[] y = {31,29,54,94,75,36,47,118,92,10}; 



     TimeSeries series = new TimeSeries("Line1"); 
     for (int i=0;i<x.length;i++){ 
      series.add(x[i],y[i]); 
     } 

     int[] x2 = {1,2,3,4,5,6,7,8,9,10}; 
     int[] y2 = {39,145,35,87,2,65,48,49,100,106}; 

     TimeSeries series2 = new TimeSeries("Line2"); 
     for (int i=0;i<x2.length;i++){ 
      series.add(x2[i],y2[i]); 
     } 



     XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); 
     dataset.addSeries(series); 
     dataset.addSeries(series2); 



     XYSeriesRenderer renderer = new XYSeriesRenderer(); 
     renderer.setColor(Color.CYAN); 
     renderer.setPointStyle(PointStyle.SQUARE); 
     renderer.setFillPoints(true); 
     renderer.setLineWidth(3); 
     renderer.setDisplayChartValues(true); 

     XYSeriesRenderer renderer2 = new XYSeriesRenderer(); 
     renderer2.setColor(Color.BLACK); 
     renderer2.setPointStyle(PointStyle.CIRCLE); 
     renderer2.setFillPoints(true); 
     renderer2.setLineWidth(3); 
     renderer2.setDisplayChartValues(true); 

     XYMultipleSeriesRenderer mrenderer = new XYMultipleSeriesRenderer(); 
     mrenderer.addSeriesRenderer(renderer); 
     mrenderer.addSeriesRenderer(renderer2); 

     mrenderer.setChartTitle("title"); 

     mrenderer.setBackgroundColor(Color.WHITE); 

     mrenderer.setShowGrid(true); 
     mrenderer.setApplyBackgroundColor(true); 

     mrenderer.setXTitle("Days"); 
     mrenderer.setYTitle("datas"); 

     mrenderer.setGridColor(Color.GRAY); 
    // mrenderer.setZoomButtonsVisible(true); 

     Intent intent = ChartFactory.getLineChartIntent(context, dataset, mrenderer, "Line graph title"); 
     return intent; 

    }

几乎一样的视频。但我不工作，而不是得到两条不同的路线，我只有一条。当第一行（x）的最后一个数据结束时，它转到第二行（x2）的第一个数据，所以第二行从第一行继续。在此先感谢！

不应该如下：

series.add(x2[i],y2[i]);

是实际：

series2.add(x2[i],y2[i]);

注意 '2'。

TimeSeries series = new TimeSeries("Line1"); 
    for (int i=0;i<x.length;i++){ 
     series.add(x[i],y[i]); 
    } 

    int[] x2 = {1,2,3,4,5,6,7,8,9,10}; 
    int[] y2 = {39,145,35,87,2,65,48,49,100,106}; 

    TimeSeries series2 = new TimeSeries("Line2"); 
    for (int i=0;i<x2.length;i++){ 
     series2.add(x2[i],y2[i]); // The change is here... 
    }
