![奇怪的大括号 tikz/装饰](https://linux22.com/image/321386/%E5%A5%87%E6%80%AA%E7%9A%84%E5%A4%A7%E6%8B%AC%E5%8F%B7%20tikz%2F%E8%A3%85%E9%A5%B0.png)
在我尝试使用的每个程序中,括号的右端编译时都很奇怪。有人能帮我吗?

答案1
->
由于您在所有行中使用,因此在这里
\begin{tikzpicture}[shorten >=1pt,->,draw=black!50, node distance=\layersep]
您需要添加-
此行,以便->
不使用默认行,因此正确的行是
\draw[decoration=brace, decorate,-] ...
