TikZ箭头取代交点

Question

我试图使用交点作为关节将一条弯曲路径连接到另一条弯曲路径（两个弯曲边），但是当向第二条路径添加样式为“-latex”的箭头时，曲线略有位移，交点错误。

\begin{tikzpicture}
\draw
  node (A) at (-2,-2) {A}
  node (B) at ( 0,-3) {B}
  node (C) at (-2,-4) {C}
;

\draw [name path=line] (-2,-3.5) -- (-1,-3.5);
\draw [-latex] (A) edge [bend left=45,name path=curve] (C);
\draw [name intersections={of=curve and line}] (B) edge [bend right] (intersection-1) ;
\end{tikzpicture}

下面是上述代码中含有和不含错误的图像。

是什么原因造成的？如何解决？

Answer 1

解决方法：\usetikzlibrary{bending}。这样弯曲箭头的箭头就能更好地跟随曲线：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{bending}
\usetikzlibrary{intersections}
\begin{document}
\begin{tikzpicture}
\draw
  node (A) at (-2,-2) {A}
  node (B) at ( 0,-3) {B}
  node (C) at (-2,-4) {C}
;

\draw [name path=line] (-2,-3.5) -- (-1,-3.5);
\draw [-latex] (A) edge [bend left=45,name path=curve] (C);
\draw [name intersections={of=curve and line}] (B) edge [bend right]
(intersection-1) ;
\end{tikzpicture}
\end{document}
