Answer 1

js真的不怎么懂、、、 var options = {
         chart: {
                renderTo:'',
                type: 'spline'
            },
            title: {
           text: '',
          x: -20
      },
       
     xAxis:{
      },
       yAxis: {
          title: {
              text: '金额（元）'
          },
          plotLines: [{
              value: 0,
              width: 1,
              color: '#808080'
          }]
      },
      series: [],
      tooltip: {
          valueSuffix: '元'
      },
       
      plotOptions: {
               spline:{
                   dataLabels: {
                  enabled: true
               },
               animation:false,
             },
       },
    };
    
         
        var categories = [];
        var datas = [];        //南京片区
        function queryData() {
            $.ajax({
                url:'__APP__/Company/njpq',
                type:'get',
                dataType:"json",
                success:function(data) {
                 for (var a = 0; a < data.length; a++) {        
                     categories[a] = data[a][0]['RiQi'];
                     alert(categories[a]);
                     for (var j = 0; j <data[a].length;j++) {
                         datas[j] =  (typeof(datas[j]) == 'undefined' ? new Array(data.length) : datas[j]);  
                         options.series
                         options.series[j].name = data[a][j]["KHMC"];
                         datas[j][a] = data[a][j]['JE']*1;
                         options.series[j].data = datas[j];
    
                     }      
                 }
                
                        options.title.text = '南京片区';
                        options.chart.renderTo='njpq';
                        options.xAxis.categories = categories;
                        chart = new Highcharts.Chart(options);
                }
            });
        }加在哪边呢？

Answer 2

for(.....){
options.series.push({})
}

Answer 3

        //南京片区
        function queryData() {
            $.ajax({
                url:'__APP__/Company/njpq',
                type:'get',
                dataType:"json",
                success:function(data) {
                    for (var a = 0; a < data.length; a++) {        
                        categories[a] = data[a][0]['RiQi'];
                        alert(categories[a]);                         for (var j = 0; j <data[a].length;j++) {
                            datas[j] =  (typeof(datas[j]) == 'undefined' ? new Array(data.length) : datas[j]);  
                            options.series.push({});//不用很复杂, 用一个加一个
                            options.series[j].name = data[a][j]["KHMC"];
                            datas[j][a] = data[a][j]['JE']*1;
                            options.series[j].data = datas[j];
     
                        }      
                    }
                     
                        options.title.text = '南京片区';
                        options.chart.renderTo='njpq';
                        options.xAxis.categories = categories;
                        chart = new Highcharts.Chart(options);
                }
            });
        }

数据来自接口，那你需要在回调函数中写这段代码

Answer 5

這段代碼似曾相識阿…for (var a = 0; a < data.length; a++) {
    categories[a] = data[a][0]['RiQi'];
    alert(categories[a]);    for (var j = 0; j < data[a].length; j++) {
        datas[j] = (typeof (datas[j]) == 'undefined' ? new Array(data.length) : datas[j]);
        options.series[j] = (typeof (options.series[j]) == 'undefined' ? new Object() : options.series[j]);
        options.series[j].name = data[a][j]["KHMC"];
        datas[j][a] = data[a][j]['JE'] * 1;
        options.series[j].data = datas[j];    }
}options.series[j] 一樣要經過檢查，不檢查會串到突破天際
未定義則new Object() 或是 {} 也可，
 不過new Object()  運行速度快20%

Answer 6

直接操作对象就好了，看上是extjs的图表
