如何在饼图中创建动态值

Question

这里我使用饼图，我给出静态值意味着它工作正常，但我想要动态值而不是静态

1. ['单人占用的旅行'，2845]而不是我必须给['单人占用的旅行'，40]， 因为employeeTraveld 1表示total_Trip是40 像这样我必须给剩下的四个值

  

我尝试过这样但是没有骚扰

            var res=jQuery.parseJSON(result);// convert the json
        console.log(res);


            $.each( res['data'], function( key, value ) { 
                var employeeTraveld = value.employeeTraveld;
                var total_Trip = value.total_Trip;
                console.log(employeeTraveld + " = "+ total_Trip);

                {
                  "status": "success",
                  "data": [
                    {
                      "employeeTraveld": "1",
                      "total_Trip": "40"
                    },
                    {
                      "employeeTraveld": "2",
                      "total_Trip": "19"
                    },
                    {
                      "employeeTraveld": "3",
                      "total_Trip": "26"
                    },
                    {
                      "employeeTraveld": "4",
                      "total_Trip": "21"
                    }
                  ]
                }


                var data = google.visualization.arrayToDataTable([
                      ['Task', 'Hours per Day'],
                      ['Trip With Single Occupancy',     if(employeeTraveld == 1){total_Trip}],
                      ['Trip With Two Occupancy',      if(employeeTraveld == 2){total_Trip}],
                      ['Trip With Three Occupancy',  if(employeeTraveld == 3){total_Trip}],
                      ['Trip With Four Occupancy', if(employeeTraveld == 4){total_Trip}]
                    ]);
            });

google.setOnLoadCallback(drawChart);
      function drawChart() {

				var result =	{
					  "status": "success",
					  "data": [
						{
						  "employeeTraveld": "1",
						  "total_Trip": "40"

					  ]
					}
					
					//console.log(result);
			
			 var data = google.visualization.arrayToDataTable([
					  ['Task', 'Hours per Day'],
					  ['Trip With Single Occupancy',     2845],
					  ['Trip With Two Occupancy',      2717],
					  ['Trip With Three Occupancy',  5369],
					  ['Trip With Four Occupancy', 1723]
					]); 
					
					var options = {
				  title: 'My Daily Activities'
				};

				var chart = new google.visualization.PieChart(document.getElementById('piechart'));

				chart.draw(data, options);
