没人研究Jfreechart么?

Question

N个地方贴问题了,就是没人答.小弟我要实现在一个jsp页面上画出两个曲线图,每个图都是以时间为x轴,多纵轴.并且要在鼠标指向各个数据点的时候显示其坐标.
写了一个方法
  public void drawMoreZheXian(ArrayList TimeSeriesLIst, ArrayList showList,
                              ArrayList colorList, String[] groupArr,
                              String[] titleArr, String zmStr,
                              JspWriter out, int width, int height,
                              String[] colorArr, int bgcolor) {
    CombinedDomainXYPlot plot = new CombinedDomainXYPlot(new DateAxis(zmStr));
    if (groupArr != null && groupArr.length >= 1) {      for (int i = 0; i < groupArr.length; i++) {
   //String[] numArr = groupArr[i].split(",");
//循环把各组值放到 collection中
TimeSeriesCollection  dataset = new TimeSeriesCollection();
        dataset.addSeries( (TimeSeries) TimeSeriesLIst.get(i));//生产工具提示信息的ArrayList
        ArrayList[] tooltips = new ArrayList[showList.size()];
        for (int k = 0; k < showList.size(); k++) {
          tooltips[k] = getCurveSeries( (String[]) showList.get(k));
        }        ////////////////////////井数
        NumberAxis rangeAxis1 = new NumberAxis(titleArr[i]);        CustomXYToolTipGenerator ttg1 = new CustomXYToolTipGenerator();
        //加入各条曲线的工具提示条
          ttg1.addToolTipSeries(tooltips[i]);        //生成曲线的透视层
        StandardXYItemRenderer renderer1 = new StandardXYItemRenderer(
            StandardXYItemRenderer.SHAPES_AND_LINES,
            ttg1, null);
        rangeAxis1.setAutoRangeIncludesZero(false);
        rangeAxis1.setAutoRangeStickyZero(false);
        //设置小数位数
        rangeAxis1.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
        XYPlot subplot1 = new XYPlot(dataset, null, rangeAxis1, renderer1);
        subplot1.setBackgroundPaint(new GradientPaint(0, 100,
            new Color(0xccccff), 130, 240, new Color(0xeffcd0), true));
        plot.setDomainGridlinePaint(Color.white);
        plot.setRangeGridlinePaint(Color.white);
        plot.setAxisOffset(new RectangleInsets(5.0, 5.0, 5.0, 5.0));
        plot.add(subplot1, 1);
        plot.setBackgroundPaint(new Color(bgcolor));
        if (colorList != null && colorList.size() > 0) {
          renderer1.setSeriesPaint(0, (Color) colorList.get(i));
        }        rangeAxis1.setAutoRange(true);      JFreeChart chart = new JFreeChart("",
                                          JFreeChart.DEFAULT_TITLE_FONT, plot, false);
        chart.setBackgroundPaint(new Color(bgcolor));        plot.setDomainCrosshairVisible(false);
        plot.setRangeCrosshairVisible(false);        DateAxis axis = (DateAxis) plot.getDomainAxis();
        axis.setTickUnit(new DateTickUnit(DateTickUnit.DAY, 1,
                                          new SimpleDateFormat("MM-dd")));
        XYItemRenderer xyitemrenderer = plot.getRenderer();
        if (xyitemrenderer instanceof XYLineAndShapeRenderer) {
          XYLineAndShapeRenderer xylineandshaperenderer = (XYLineAndShapeRenderer)
              xyitemrenderer;
          xylineandshaperenderer.setBaseShapesVisible(true);
          xylineandshaperenderer.setBaseShapesFilled(true);
        }
        FileOutputStream fos_jpg = null;
        String[] imgUrl = null;
        ChartRenderingInfo info = null;
        try {
          imgUrl = ImgScgz.getImgUrl();
          fos_jpg = new FileOutputStream(imgUrl[0]);
          info = new ChartRenderingInfo();
          ChartUtilities.writeChartAsJPEG(fos_jpg, 100, chart, width, height, info); //图形的大小        }
        catch (Exception e) {
        e.printStackTrace();
         }
         finally {
           try {
             fos_jpg.close();
           }
           catch (Exception e) {}
         }
         try {
           out.print("<img src=" + imgUrl[1] + " border=0 usemap=#mapName>");
           out.print(ChartUtilities.getImageMap("mapName", info));
         }
         catch (Exception e) {}   }
}方法getCurveSeries内容
  public ArrayList getCurveSeries(String[] str) {
    //所对应的工具提示
    ArrayList toolTips = new ArrayList();
    for (int i = 0; i < str.length; i++) {
      toolTips.add(str[i]);
    }
    return toolTips;
  }然后在jsp中调用两次这个方法,只是传递的参数不一致,但是只能显示前一个图的数据点,后一个死活出不来.貌似还是用的前一个的tooltips,因为有时两边数据一致的时候就能显示.日志里打出来的数据是又是对的.总之我是晕了,不知道怎么解决!
请教高手是怎么回事?

Answer 1

用debug试试，可能很多人都不熟悉

Answer 2

不应该调用两次，应该是一副图，jfreechart好像有做组合图的方法

Answer 3

感谢各位关注!

我的意思是:我在一个jsp页面中,要显示两付图,只是两个图关注的数据不相同,但是都是一种类型的图.所以调用两次.
其实换个例子到无所谓,但是我想知道为什么不行.

Answer 5

jfreechart是不是没前途啊
好像都没人解答
