树中节点的右移

我想将一个节点向右移动，因为它与另一个节点重合：

没有说明

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{trees}

\begin{document}

\begin{tikzpicture}[sibling distance=2.5cm, level distance=2.5cm]
\node {S}
  child {[dotted]  node {\{E.v:=0\}}}
  child {  node {E}
  child{[dotted]  node {\{T.v:=1\}}}
  child {  node {T}
  child {  node {F}
  child {  node {NB}}
  child{[dotted]  node {\{F.v:=SR(NB)\}}}}
  child{[dotted]  node {\{T.v:=T.v*F.r\}}}
  child [sibling distance=2cm]{  node {R2}
  child  {  node {$\varepsilon$}}}}
  child{[dotted]  node {\{E.v:=E.v+T.v\}}}
  child {  node {R1}
  child[sibling distance=0.8cm]{[dotted]  node {\{T.v:=1\}}}
  child [sibling distance=0.5cm]{  node {+}}
  child {  node {T}
  child {  node {F}
  child {  node {NB}}
  child{[dotted]  node {\{F.v:=SR(NB)\}}}}}
  child{[dotted]  node {\{E.v:=E.v+T.v\}}}
  child {  node {R1}
  child {  node {$\varepsilon$}}} }}
;
\end{tikzpicture}

最好sibling distance为每个级别一致地定义 s。我\tikzset在下面的代码中使用了它，但您也可以将级别样式设置为环境选项tikzpicture。

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{trees}

\begin{document}

\begin{tikzpicture}[level distance=2.5cm]

% Setting sibling distance for each level of the tree
\tikzset{
  level 1/.style={sibling distance=4cm},
  level 2/.style={sibling distance=3.5cm},
  level 3/.style={sibling distance=1.8cm},
}

\node {S}
  child {[dotted]  node {\{E.v:=0\}}}
  child {  node {E}
  child{[dotted]  node {\{T.v:=1\}}}
  child {  node {T}
  child {  node {F}
  child {  node {NB}}
  child{[dotted]  node {\{F.v:=SR(NB)\}}}}
  child{[dotted]  node {\{T.v:=T.v*F.r\}}}
  child {  node {R2}
  child  {  node {$\varepsilon$}}}}
  child{[dotted]  node {\{E.v:=E.v+T.v\}}}
  child {  node {R1}
  child {[dotted]  node {\{T.v:=1\}}}
  child {  node {+}}
  child {  node {T}
  child {  node {F}
  child {  node {NB}}
  child{[dotted]  node {\{F.v:=SR(NB)\}}}}}
  child{[dotted]  node {\{E.v:=E.v+T.v\}}}
  child {  node {R1}
  child {  node {$\varepsilon$}}} }}
;
\end{tikzpicture}

\end{document}
