arcgis javascript api - Polyline not showing on esri maps

I have list of points. I am pushing these points to an array. Now when i draw polyline through esri map graphics.add then its not shwoing anything.

My code for drawing polyline on esri map is as follows:

  var Points = new Array();
            var PointsGoogle = new Array();
            for (VIndex = 0; VIndex < ItemList.Coordinates.length; VIndex++)
            {
             latlng = new  esri.geometry.Point(ItemList.Coordinates[VIndex].X,ItemList.Coordinates[VIndex].Y);


                Points.push(latlng);

                //  polyline.addPath([new esri.geometry.Point(10,10), new esri.geometry.Point(20,20), new esri.geometry.Point(30,30)]);
            }

      var polylineSymbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([204, 102, 51]), 4);
          var polyline = new esri.geometry.Polyline(esrimap.spatialReference);
      polyline.addPath(Points);
      esrimap.graphics.add(new esri.Graphic(polyline, polylineSymbol));
