减少森林中节点标签和连接线之间的距离

Question

我使用以下代码来生成像图中左边两棵树。

\documentclass{minimal}

\usepackage{forest}

\forestset{
sn edges/.style={for tree={parent anchor=south, child anchor=north,align=center,base=bottom,where n children=0{tier=word}{}}}, 
background tree/.style={for tree={text opacity=0.2,draw opacity=0.2,edge={draw opacity=0.2}}}
}


\begin{document}

\begin{forest}
sn edges
[S
  [NP [er\\he] ]
  [NP
    [Det [das\\the] ]
    [N [Buch\\book] ] 
  ]
  [NP
    [Det [der\\the] ]
    [N [Frau\\woman] ] 
  ]
  [V [gibt\\gives] ]
]
\end{forest}

\end{document}

我想减少这个距离，以便它看起来像右边的树（用 绘制tikz-qtree）。有没有办法做到这一点（并将其设置为默认值）？

Answer 1

你想要类似的东西吗

l sep-=<some length>

这将减少层之间的距离<some length>？

下面分别将默认值与1em和的减少进行比较2em：

\documentclass{standalone}

\usepackage{forest}

\forestset{
sn edges/.style={for tree={parent anchor=south, child anchor=north,align=center,base=bottom,where n children=0{tier=word}{}}},
background tree/.style={for tree={text opacity=0.2,draw opacity=0.2,edge={draw opacity=0.2}}}
}


\begin{document}

\begin{forest}
sn edges
[S
  [NP [er\\he] ]
  [NP
    [Det [das\\the] ]
    [N [Buch\\book] ]
  ]
  [NP
    [Det [der\\the] ]
    [N [Frau\\woman] ]
  ]
  [V [gibt\\gives] ]
]
\end{forest}
\begin{forest}
  for tree={
    l sep-=1em,
  },
sn edges
[S
  [NP [er\\he] ]
  [NP
    [Det [das\\the] ]
    [N [Buch\\book] ]
  ]
  [NP
    [Det [der\\the] ]
    [N [Frau\\woman] ]
  ]
  [V [gibt\\gives] ]
]
\end{forest}
\begin{forest}
  for tree={
    l sep-=2em,
  },
sn edges
[S
  [NP [er\\he] ]
  [NP
    [Det [das\\the] ]
    [N [Buch\\book] ]
  ]
  [NP
    [Det [der\\the] ]
    [N [Frau\\woman] ]
  ]
  [V [gibt\\gives] ]
]
\end{forest}

\end{document}
