biChordChart (bidirectional chord diagram | 有向弦图)

bidirectional/directed/self-loop/self-links chord diagram 有向弦图

bidirectional chord diagram 有向弦图

Basic usage

dataMat=randi([0,8],[6,6]);

% 添加标签名称

The 'SSqRatio' attribute can be used to adjust

the ratio of arc-shaped blocks at the end of the chord
