znn0105 opened a new issue #12479:
URL: https://github.com/apache/incubator-echarts/issues/12479
### Version
4.2.1
### Steps to reproduce
series里同时存在多个type为lines的对象，effect里的trailLength(尾迹长度)会被共用
### What is expected?
多个lines同时存在时，可以分别设置不同的trailLength尾迹长度
### What is actually happening?
只要其中一个lines的trailLength不为0，其他lines的trailLength 即使设置为0也无效

修改配置即可： https://gallery.echartsjs.com/editor.html?c=xK85XdQJZO&v=3
参考文档：https://echarts.apache.org/zh/option.html#series-lines.effect
所有带有尾迹特效的图表需要单独放在一个层，也就是需要单独设置 zlevel。当然如果不同的 trailLength Effect lines 系列，需要设置不同的 zlevel，以方便 canvas 去做不同的 trailLength 渲染。
```
{
type:"lines",
coordinateSystem: "cartesian2d",
lineStyle:{
width:0
},
zlevel:3, // 与第一个 Effect 系列不同的 zlevel 即可
effect:{
show:true,
symbol:"circle",
symbolSize:4,
color:"#23E0FF",
trailLength:0.4
},
data:[
{name:"lyxtLine1",coords:[[73,48],[73,75]]},
{name:"lyxtLine2",coords:[[75,38],[75,65]]},
{name:"lyxtLine3",coords:[[95,23],[95,50]]},
{name:"lyxtLine4",coords:[[135,35],[135,75]]},
{name:"lyxtLine5",coords:[[120,55],[120,83]]},
{name:"lyxtLine6",coords:[[142,45],[142,65]]},
]
}
```
