根据数据格式

dataGoz: [{
        "xAxis": ["2017-3-1", "2017-3-15", "2017-4-1", "2017-4-12", "2017-5-21", "2017-6-5", "2017-8-12", "2017-9-1", "2017-10-11"],
        "yAxis": [
          { "name": "TT", "data": ["23", "56", "32", "41", "32", "45", "39", "47", "58"] },
          { "name": "KK", "data": ["23333", "34533", "32234", "25551", "34265", "35032", "23332", "27932", "22438"] }
        ],
        "name": "温度"
      }]

动态实现效果

  <div>
    <div v-for="(dataset, index) in dataGoz" :key="index" :ref="'chart' + index"
      style="width: 600px; height: 200px; margin-bottom: 20px;" v-loading="loading"></div>
  </div>
