1.第一种：后台绑定
前台
  var options = new Highcharts.Chart({
                     chart: {
                         //将报表对象渲染到层上  
                         renderTo: 'container'
                     },title: {
                         text: ''
                     },xAxis: {
                         categories: ['1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20']
                     },labels: {
