在节点之间的每个箭头之间创建更多空间

Question

我怎样才能使我画的箭头稍微粗一些并且与我拥有的每个节点之间的距离更远？

编辑：有没有比搜索 TexStackExchange 更好的方法来自己解决这些内容（就像一本流行的参考手册？）

\documentclass{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{tikz}

\begin{document}
\centering
\begin{tikzpicture}
  [scale=1.3,auto=left,every node/.style={rectangle,fill=blue!20}]
  \node (n8) at (1,10) {FGWC / / };
  \node (n7) at (1,8)  {WC / $\rightarrow$ / FG};
  \node (n6) at (1,6)  {WCF / $\leftarrow$ / G};
  \node (n5) at (1,4) {C / $\rightarrow$ / GFW};
  \node (n4) at (1,2)  {CFG / $\leftarrow$ / W};
  \node (n3) at (1,0)  {G / $\rightarrow$ / WFC};
  \node (n2) at (1,-2) {GF / $\leftarrow$ / WC};
  \node (n1) at (1,-4) {/ $\rightarrow$ / WCGF};

\draw [->] 
(n8) edge (n7) 
(n7) edge (n6) 
(n6) edge (n5)
(n5) edge (n4)
(n4) edge (n3)
(n3) edge (n2)
(n2) edge (n1);
\end{tikzpicture}

\end{document}

在pgfmanual我看来还不错，还有 VisualTi钾Z. 您可以用 缩短箭头shorten，用 使它们变粗thick。

\documentclass{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{tikz}

\begin{document}
\centering
\begin{tikzpicture}
  [scale=1.3,auto=left,every node/.style={rectangle,fill=blue!20}]
  \node (n8) at (1,10) {FGWC / / };
  \node (n7) at (1,8)  {WC / $\rightarrow$ / FG};
  \node (n6) at (1,6)  {WCF / $\leftarrow$ / G};
  \node (n5) at (1,4) {C / $\rightarrow$ / GFW};
  \node (n4) at (1,2)  {CFG / $\leftarrow$ / W};
  \node (n3) at (1,0)  {G / $\rightarrow$ / WFC};
  \node (n2) at (1,-2) {GF / $\leftarrow$ / WC};
  \node (n1) at (1,-4) {/ $\rightarrow$ / WCGF};

\draw [-latex,thick,shorten >=1pt,shorten <=1pt] 
(n8) edge (n7) 
(n7) edge (n6) 
(n6) edge (n5)
(n5) edge (n4)
(n4) edge (n3)
(n3) edge (n2)
(n2) edge (n1);
\end{tikzpicture}

\end{document}
