callmeYe opened a new issue #8925: line3D中画的线为折线
URL: https://github.com/apache/incubator-echarts/issues/8925
<!--
为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。
-->
### One-line summary [问题简述]
使用line3D绘制流向图，绘制出来的线是不平滑的折线，不知道有什么办法可以更改线的平滑程度。
### Version & Environment [版本及环境]
+ ECharts version [ECharts 版本]: ECharts 4.1.0
+ Browser version [浏览器类型和版本]: Chrome 68.0.3440.84
+ OS Version [操作系统类型和版本]: WIN7 SP1
### Expected behaviour [期望结果]
希望绘制出来的线可以是圆滑的曲线。
### ECharts option [ECharts配置项]
<!-- Copy and paste your 'echarts option' here. -->
<!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
```javascript
option = {
