Question

I am trying to update a jqplot chart dynamically with Ajax requests.
My server is returning a string represtation of the data as such:

“[[‘Juice’,30],[‘Milk’,30],[‘Water’,30]]”

However I need to convert this string into an array of arrays.
Is this the correct approach to update the data and if so what is the best way to convert the string.

   $.ajax({
       url:'http://localhost',
       success:function(plotData){
       var data = plotData.split(","); 
         if(plot){
             plot.series[0].data = data;
             plot.redraw();
         }
       },
       fail:function(error){
          alert('error:'+error);         
       }
   });   

This code will convert into a one dimentional array:

0: “[[‘Helpdesk'”
1: “30]”
2: “[‘Users'”
3: “30]”
4: “[‘Auto Generated'”
5: “30]]”

You can use eval("var x= " + plotData) as an alternate solution. There are few dangers in using eval, please go through it before using it.
