   > 3D中的散点图，有个高度因素，这个因素是根据data中的第三个数值来决定的，数据小 就埋在了地图里面了。也就是球的高度小于球的半径了。

   > ```
   > {
   > type: 'scatter3D',
   > data: [
   >   [.., .., 1],     // 高度会很低
   >   [.., .., 100] 
   > ]
   > }
   > ```
   > 
   > 所以，可以统一一下 `data` 中的第三个数值，使其保证高度大于半径就好

   > ```
   > {
   > type: 'scatter3D',
   > data: [
   >   [.., .., 80, 1],     // 把高度抬高
   >   [.., .., 80, 100] 
   > ]
   > },
   > // 设置球的半径大小，如果需要的话
   > symbolSize (val) {
   >   return val[3] // val中的第三个数是80， 第四个是原始的数值
   > }
   > ```
   在版本5.0.2这个版本,这个方法并不行
