我给他的思路是：直接使用风玫瑰图可以画出。

rose_bar
本次我的更新和这个有些不同！是环形柱状图，可调节细节多；
只需要函数：可实现各个方面：
欢迎持续投稿，宣传自己的工作（不限代码论文等方面）！
rose_bar
使用简单：

输入数据和参数

[ph,fs] =rose_bar(datax,datay,r,R,bw1,xtickvalue);
% note: datax is x;
% datay is y;
% r is inner circle
% R is circle
% bw1 is width of bar,from 2 to inf; 2 is full; increase then thin bar;    %
% ph can control line of circle;;
% fs can control line and face color of bar

先看些结果：在解释如何做出:

默认图，所有颜色一致：

可使用代码调节某一个柱状图的颜色：
例如第十四（14）个为蓝色：
set(fs(14),‘FaceColor’,‘b’,‘EdgeColor’,‘b’)

可调节每一个颜色都不同：

可控制中心⚪的大小
⚪为零：在这里插入图片描述

⚪为大：

可以加单位：一个或多个或全部

可以什么都不要

可以更改xtick

总而言之，挺强的！
