   @Ovilia Hi Ovilia, I have tested using different zlevels, but it does not 
work in this situation. I even give each series different zlevel but the lines 
will still disappear while the scatters left there. 
   Below is the test case, you can replace the original **option** with the 
code below:

   myChart.setOption({
       // backgroundColor: '#404a59',
       title: {
           text: '全国主要城市空气质量',
           subtext: 'data from PM25.in',
           sublink: 'http://www.pm25.in',
           left: 'center',
           textStyle: {
               color: '#fff'
           }
       },
       tooltip : {
           trigger: 'item'
       },
       bmap: {
           center: [104.114129, 37.550339],
           zoom: 5,
           roam: true
       },
       series : [
           {
               id: 'scatter',
               name: 'pm2.5',
               type: 'scatter',
               zlevel:0,
               coordinateSystem: 'bmap',
               data: [],//convertData(data),
               symbolSize: function (val) {
