向下钻取动态值不起作用的图表。使用json我得到了所有动态值

Question

任何机构，请帮助我动态显示向下钻取图表。我正在尝试整合rgraph。但是使用静态值，一切正常。当我将其更改为动态问题时。第一次出现时间图表。点击该栏时显示为空。

我使用json编码将所有动态值存储在php数组中。以下是我使用json的jquery代码，我获得了所有值，但图表未显示。正在显示静态值图表

Data Json value=
{\"JFET\":\"2700,2325,2700,2700,7300,2700,2700,2700,2325,2700,2325,
 1204,2700,2100,2700,2700,2700,2700,800,2700,2200,2700,800,800,800,
 800,2325,2700,2325,2325,2700,0\"}
Lbel Json value=
{\"JFET\":\"'collegename1','collegename2','collegename3','collegename4'
 \"}etc

我同样得到了28种产品。 这些值在onclick函数上得到了

   var myJSONlabel = JSON.parse(objarrlabel);
  // alert(myJSON.JFET);//alert(objarr) 
    var ca = document.getElementById("cvs");
    var data           = [<?=$label1?>]; //alert(data.length)
