大家好:
想問用fusionchart想畫出2條折線圖
但我卻只能畫一條，第2條就會讓頁面變空白....不然就是A線接B線後面畫下去...
以下是程式碼:

<%   
String pro[]={"一月","二月","三月","四月","五月","六月","七月","八月","九月","十月","十一月","十二月","total"};  
    double proform[]=new double [13];   
    double proformt[]=new double [13];   
    for(int i=0;i<proform.length;i++){proform[i]=i*10;}
      for(int i=0;i<proformt.length;i++){proformt[i]=i*10+10;}
%>
<%
            String chartXML = "<chart __attributes__>__set__</chart>";  
             String chartXML1 = "<chart __attributes__>__set__</chart>";
            String attributeTemplate = "__key__=\"__value__\" ";
            
            String setXMLTemplate = "<set label=\"__label__\" value=\"__value__\" />";
             String setXMLTemplate1 = "<set label=\"__label__\" value=\"__value__\" />";
            Map<String, String> dataobj = new HashMap<String, String>();     
            for(int i=0;i<pro.length;i++){dataobj.put(pro[i] ,Double.toString(proform[i]));}
             for(int i=0;i<pro.length;i++){dataobj.put(pro[i] ,Double.toString(proformt[i]));}
            ArrayList<String> setList = new ArrayList<String>();
           
          for(int i=0;i<pro.length-1;i++)
            {                
                String tempSetTemplate = setXMLTemplate;
                tempSetTemplate = tempSetTemplate.replaceAll("__label__", pro[i]);
                tempSetTemplate = tempSetTemplate.replaceAll("__value__", Double.toString(proform[i]));   
                setList.add(tempSetTemplate);    
            } 
           for(int i=0;i<pro.length-1;i++)
            {                
                String tempSetTemplate = setXMLTemplate1;
                tempSetTemplate = setXMLTemplate1.replaceAll("__label__", pro[i]);
                tempSetTemplate = setXMLTemplate1.replaceAll("__value__", Double.toString(proformt[i]));   
                setList.add(tempSetTemplate);    
            } 
         
            StringBuilder chartAttributeString = new StringBuilder();          
            StringBuilder setAttributeString = new StringBuilder();
           
            for(String s: setList)
            setAttributeString.append(s);
                       
            chartXML = chartXML.replaceAll("__attributes__",  chartAttributeString.toString());          
            chartXML = chartXML.replaceAll("__set__",  setAttributeString.toString());
            chartXML1 = chartXML1.replaceAll("__attributes__",  chartAttributeString.toString());          
            chartXML1 = chartXML1.replaceAll("__set__",  setAttributeString.toString());
            FusionCharts1 columnChart= new FusionCharts1(
            "line",// chartType pie2d bar2d column2d gantt line pie2d            
                        "chart1",// chartId
                        "800","500",// chartWidth, chartHeight
                        "chart",// chartContainer
                        "xml",// dataFormat
                       chartXML,//dataSource
                    chartXML1
                    );  
  
            %>

我都在FusionCharts1中多加一個參數dataSource1了，但為何還是不行呢??

java的程式碼
