MATLAB | 这些美丽大方的弦图居然都是用MATLAB画的？

什么？这些美丽大方的弦图都是MATLAB画的？？？

没错都是由我本人开发的弦图绘制工具包实现的：

  • chord chart 弦图https://www.mathworks.com/matlabcentral/fileexchange/116550-chord-chart
  • Digraph chord chart 有向弦图 https://www.mathworks.com/matlabcentral/fileexchange/121043-digraph-chord-chart

这俩工具包可以去链接所示地址下载，也可去文末所示的gitee仓库下载，本期只展示怎么调用函数绘图，篇幅问题就不把工具函数进行展示了，请自行下载工具包。当然也可以直接去文末所示gitee仓库下载整和好的全部文件。

编写本篇文章的原因是，已经由很多人开始使用我开发的弦图绘制工具，但是对一些样式能不能设置不太了解，作为开发者也算是比较了解工具的实现原理，能比较灵活的运用，于是就萌生了挑战绘制各种样式弦图的想法，目前有的代码并不算短，未来有可能我会将一部分代码集成进工具里，让大家能够一两行代码实现以下好多行代码的效果。废话不多说，来看这个MATLAB工具包当前版本能做到什么程度叭：
