   If need, you can use bmap and you will meet the same issue. For example, if you first render the first two series by giving them data and setOption, and then update the data to any of the last two series by setoption({series: [{
   id: 'shunt',
   name: 'shunt',
   data: [{
   name: 'blah',
   value: [-86, 40] //for example
   }]
   }]})
   then you will find the scatter in series 0 still there but the lines in series 1 disapper. Need help to fix this bug! Thanks!!!
