Flot and PHP

Flot and PHP

Hello I am trying to populate a flot chart using PHP but things do not seem to be working. If I put in the numbers manually for the chart everything is working fine but if I pass them via ajax from a php script nothing displays.

here is my php:
$array = array();
      
      $array[] = array(strtotime($result[0][1] ."UTC") * 1000,round($result[0][0],1));
      $array[] = array(strtotime($result[1][1] ."UTC") * 1000,round($result[1][0],1));
      $array[] = array(strtotime($result[2][1] ."UTC") * 1000,round($result[2][0],1));
      $array[] = array(strtotime($result[3][1] ."UTC") * 1000,round($result[3][0],1));
      $array[] = array(strtotime($result[4][1] ."UTC") * 1000,round($result[4][0],1));
      $array[] = array(strtotime($result[5][1] ."UTC") * 1000,round($result[5][0],1));
      $array[] = array(strtotime($result[6][1] ."UTC") * 1000,round($result[6][0],1));
      $array[] = array(strtotime($result[7][1] ."UTC") * 1000,round($result[7][0],1));
      $array[] = array(strtotime($result[8][1] ."UTC") * 1000,round($result[8][0],1));
      $array[] = array(strtotime($result[9][1] ."UTC") * 1000,round($result[9][0],1));
      $array[] = array(strtotime($result[10][1] ."UTC") * 1000,round($result[10][0],1));      
      
      print_r(json_encode($array));


and here is my javascript:
$(function () {
   
   var q1;
   
   $(document).ready(function() {
      //Question 1
      $.get("http://w3.sono-tek.com/modules/it_tickets/jQuery.php", { type: "s_result", value: "Q1" },
         function(c_data) {
            //q1 = eval("("+data+")").data;
            q1 = c_data;
            alert(q1);
         });
           });

var data = [
{ label: "Q1",
data: q1 }];

var options = {
      legend: {
         show: true,
         margin: 10,
         backgroundOpacity: 0.5
      },
      points: {
         show: true,
         radius: 3
      },
      lines: {
         show: true
      },
      xaxis: {
         mode: "time",
         timeformat: "%b"
         //ticks: 6,
         //tickDecimals: 0
      },
      yaxis: {
         min: 7,
         max: 10,
         tickDecimals: 0
      }
   };
   
   var plotarea = $("#plotarea");
   plotarea.css("height", "450px");
   plotarea.css("width", "700px");
   $.plot( plotarea , data, options );
});


The background of the chart appears but no data. I suspect that its because the json_encode returns a string. but any help would be greatly appreciated. Thanks.
