jquery how can I convert a json object to javascript array for jqplot

I'm using jqplot to generate charts. It works fine when I define the source data in javascript:

  var goog2 = [["6/22/2009", 425.32],["6/8/2009", 424.84],["5/26/2009", 417.23]];

I'm now trying to pull the data from a server side web method:

  <WebMethod()> _
Public Shared Function Test() As String
    Return ("[[""6/22/2009"",425.32],[""7/22/2009"",429.32]];")
End Function

No matter what I do to the returned object I can't seem to get it into the format that's required.

   function DoAction2(cat) {
          $.ajax({
              type: "POST",
              url: "AjaxTest.aspx/Test",
              data: "{cat:" + cat + "}",
              contentType: "application/json; charset=utf-8",
              dataType: "json",
              success: function(msg) {
              alert(msg.d);
                  var d = msg.d;
                  plot = $.jqplot('chart1', [d])

Any help would be appreciated.

Is the returned string from your Test() function the entire response?

In your JS you're asking for msg.d, but there's no d element in your JSON structure (as shown).

Also, the trailing semicolon shouldn't be there. It's not valid JSON.

It seems to me you're returning the exact structure you need from the server, yes? If so, then I don't understand your attempt to access 'msg.d' in your success function. 'msg' is your data structure...

Also, I have no idea what lang you're using on the server side so I don't know much about its syntax, but that does not appear to be properly escaping quotes/etc in order to produce a valid JSON response.
