Is there any way to overlap ribbons?

[jianlinyang]

I want to overlap ribbons like this I know circos.link() can do it. but this function need input sector and positions . So is there any way to overlap ribbons easily? Thank you

我想把连接各个区域的条带重叠在一起，我知道 circos.link() 能够做到 但是这个函数需要输入每个条带的起止位置和区域，这使用起来很麻烦，所有我想知道没有有函数能够简易的实现这一需求

谢谢 顾老师
