如何从API获取动态数据以呈现融合甘特图

如何解决如何从API获取动态数据以呈现融合甘特图

在这里，我想绘制一个动态融合甘特图。在下面的示例中，我对数据进行了硬编码以呈现图表。但是我需要一种动态格式。我的数据来自API，那么如何获取数据并动态传递呢？

我还希望x轴和y轴采用动态格式。

     FusionCharts.ready(function() {
  var smoPlan = new FusionCharts({
    type: 'gantt',renderAt: 'chart-container',width: '750',height: '300',dataFormat: 'json',dataSource: {
      "chart": {
        "theme": "fusion","dateformat": "mm/dd/yyyy","caption": " ","captionFontSize": "14","subCaption": "Project Plan","subCaptionFontSize": "12","milestoneFont": "Times New Roman","milestoneFontSize": "15"
      },"categories": [{
        "category": [{
          "start": "08/01/2014","end": "08/31/2014","label": "Aug '14"
        },{
          "start": "09/01/2014","end": "09/30/2014","label": "Sep '14"
        },{
          "start": "10/01/2014","end": "10/31/2014","label": "Oct '14"
        }]
      }],"processes": {
        "fontsize": "12","isbold": "1","align": "left","process": [{
          "label": "Identify Customers"
        },{
          "label": "Survey 500 Customers"
        },{
          "label": "Interpret Requirements"
        }
       ]
      },"tasks": {
        "task": [{
          "id": "1","start": "08/04/2014","end": "08/10/2014"
        },{
          "id": "2","start": "08/08/2014","end": "08/19/2014"
        },{
          "id": "3","start": "08/19/2014","end": "09/02/2014"
        }]
      },//Adding milestones to task with id 1 and 3
      "milestones": {
        "milestone": [{
          "date": "8/06/2014","taskid": "1","color": "#f8bd19","shape": "rhombus","tooltext": "Successful Completion of Development","label": " ","color": "#587B17"
        },{
          "date": "8/25/2014","taskid": "3","shape": "triangle","tooltext": "Successful Completion of Campaign","color": "#4838D2"
        }]
      }


    }
  }).render();
});

请帮助我解决这个问题！预先感谢。
