用Float Js绘制图表

Question

Not getting points on chart only can see the X and Y Axis with digits. My code of draw chart is as below

var length = 0;
var length1 = 0;
var dataXY = [];
length = allVenues.length;
 for (var i = 0; i < length; i++) {
   length1 = allVenues[i].length;
   for (var j = 0; j < length1; j++) {
    dataXY.push([allVenues[i][j].date, allVenues[i][j].price]);
   }
  }
  var result = {'label': 'chetan','data': dataXY};
  var options = {
       lines: {
        show: true
       },
       points: {
        show: true
       },
       xaxis: {
        tickDecimals: 0,
        tickSize: 1
       }
 };
 $.plot("#placeholder", JSON.stringify(result), options);

My JSON array output is like as below :

{"label":"abc","data":[["Feb 18, 2016 11:53:49 AM",12],["Feb 18, 2016 11:54:49 AM",30]]}

But still i am not able to draw a chart. I'm not able to see the points on chart as well as not getting X-Axis data as per Dates of JSON Array.
