Highcharts -导出模块

我使用highcharts来生成从数据库中提取的图形数据。

我在使用导出模块时遇到了麻烦。我已经包含了导出属性:

exporting{
  enabled:true
}

但是按钮没有出现…

我也把export .js链接到文件了…没有按钮出现…

还有其他人有这个问题吗?

代码如下:

$.ajax({
               type:"POST",
               url: "retrievechartdata.php",
           data: {questionId:qId, questionIdTwo:qIdTwo, title:title, titleTwo:titleTwo, from:from, to:to},
               dataType: "json",
               success: function(data) {
         //$("#response").html("<div class='successMessage'>"+ data.valuesTwo +"</div>");   
                   var maxY = parseInt(data.max) + 1;          
                   var minY = parseInt(data.min);          
           if(minY > 0){
             minY = 0;
           }else{
             minY -= 1;
           }
           var cdata = new Array();  
           cdata= data.values.split(',');  
           for(var i=0;i<cdata.length;i++)  
           {  
             cdata[i]= parseInt(cdata[i]);  
           } 
           var leg = false;
           var title = data.questionTitle;
           if(data.valuesTwo != "FALSE"){
             leg = true;
             title += " & "+data.questionTitleTwo; 
             var cdataTwo = new Array();  
             cdataTwo = data.valuesTwo.split(',');  
             for(var i=0;i<cdataTwo.length;i++)  
               {  
             cdataTwo[i]= parseInt(cdataTwo[i]);  
               } 
           }
              chart = new Highcharts.Chart({
