echarts中百度地图使用问题

使用环境:内网 + echart + bmap
部分代码如下:
`
initChart(){

  const defaultOption = {
    bmap: {
      center: [114.22357977409055,30.77609929995922],
      zoom: 17,
      roam: true
    },
    series: []
  }
  const baseSeriesItem = {
    type: "effectScatter",
    coordinateSystem: "bmap",
    symbolSize: [30, 30],
    showEffectOn: "render",
    rippleEffect: {
      color: 'red', //涟漪的颜色
      period: 2, //涟漪特效的动画周期
      scale: 5, //涟漪特效动画中波纹的最大缩放比例
      brushType: "fill" //涟漪特效的波纹绘制方式
    },
    label: {
      normal: {
        formatter: function(params){
          let str = `{a|${params.data.locName}}`
          // console.log(444,params)
          return str
        },
        rich: {
          a: {
            fontSize: this.$fn.getResizePx(16),
            color: "#00a7d2",
            fontWeight: "normal",
            fontFamily: "OPPO",
          }
        },
        show: true,
        position: 'top',
        // position: ["-200%", "-200%"],
        // distance: 20,
        align: "center",
        
        borderRadius: 5,
        padding: this.$fn.getResizePx(20),
        shadowColor: "rgba(0,0,0,0.16)",
        shadowBlur: 6,
        shadowOffsetX: 0,
        shadowOffsetY: 3,
        width: 200
      },
      emphasis: {
        formatter: function(params){
          let str = `{a|${params.data.locName}}
{hr|}
{a|${params.data.devId}}`
          // console.log(444,params)
          return str
        },
        rich: {
          a: {
            fontSize: this.$fn.getResizePx(18),
            color: "#fdb600",
            fontWeight: "normal",
            fontFamily: "OPPO",
          },
          hr: {
            width: '100%',
            height: 5,
            borderColor: 'transparent',
            borderWidth: 1
          }
        },
        show: true,
        opacity: 1,
        backgroundColor: {
          image: require('../../../assets/windowInfo.png')
        },
      }
    },
    itemStyle: {
      normal: {
        width: 1,
        color: 'transparent'
      }
    },
    zlevel: 1
  }
  const arr = []
  if(this.chartData.length){
    this.chartData.forEach( item => {
      if(item.isAlive === '0'){
        let obj1 = {
          data: [item],
          rippleEffect: {
            color: 'red'
          }
        }
        arr.push({...baseSeriesItem,...obj1})
      }else{
        let obj2 = {
          data: [item],
          rippleEffect: {
            color: '#4bebe9'
          }
        }
        arr.push({...baseSeriesItem,...obj2})
      }
    })
  }
  defaultOption.series = arr
  this.chart = this.$echarts.init(this.$el)
  this.chart.setOption(defaultOption)
  // 获取百度地图实例,使用百度地图自带的控件
  this.bmap = this.chart.getModel().getComponent("bmap").getBMap();
  this.bmap.setMinZoom(17); // 设置地图最小缩放比例
  this.bmap.setMaxZoom(18);
  this.bmap.addEventListener('click',e => {
    console.log(e)
  })
  this.chart.on('click', function(params){
    // alert(1);
    console.log(111,params);//此处写点击事件内容
  });
  window.addEventListener('resize', () => {
    this.chart.resize()
    // this.initChart()
  })
}

`
实现效果就是地图上的水波纹效果,如
image.png

目前有两个问题:
1:屏幕缩放时,只有点重置了位置,但是地图没变化,如
缩放前
image.png
缩放后
image.png
2:点击事件,如:点击点和地图分别对应不同事件,相当于解决事件冒泡,但用stopPropagation报错
