openlayers 5.0结合echarts迁移图_new adlayer

1.通过npm安装 ：npm install openlayers_echart
2.代码

import ADLayer from 'openlayers_echart'
//BJData数据格式  [
[[[{name:天津, value: 100, point: [106.7,32]}, {name: 北京, point: [107.9,34.3]}]]],
[[[{name:上海, value: 100, point: [108.7,32]}, {name: 大连, point: [109.9,34.3]}]]]
]
  static move(BJData){
    var convertData = function (data) {
      var res = [];
      for (var i = 0; i < data.length; i++) {
        var dataItem = data[i];
        var fromCoord =dataItem[0].point;
        var toCoord = dataItem[1].point;
        if (fromCoord && toCoord) {
          res.push([{
            coord: fromCoord,
            value: dataItem[0].value
          }, {
            coord: toCoord
          }]);
        }
      }
      return res;
    };
    var color = ['#a6c84c', '#ffa022', '#46bee9'];
    var series = [];
    BJData.forEach(function(item, i) {
      series.push(

    var option = {
      tooltip : {
        trigger: 'item'
      },
      series: series
    };
    var oe= new ADLayer(option,map,echarts)
    oe.render()
