有人能告诉我如何更改图表中突出显示的箭头的方向吗？我花了很长时间尝试做到这一点，但不知道该怎么做 :(
太感谢了！

改变
\draw[InLineArrow=0.75] (B) arc (360-180-30:360-180-30-360:0.8) node [pos=0.41, anchor=180-180,inner sep=7pt]{};
到
\draw[InLineArrow=0.25] (B) arc (360-180-30:360-180-30+360:0.8) node [pos=0.41, anchor=180-180,inner sep=7pt]{};
同样，只需编写即可实现标签 0.6
\draw[InLineArrow=0.25] (B) arc (150:150+360:0.8)node[pos=0.25,below]{0.6};
您可以避免这些长语句，请参阅 MWE：
