如何在纸上放一棵大树并改变一些节点的位置？

Question

我用以下代码制作了这棵树

    \begin{forest}
  for tree={
    rounded corners,
    draw,
    align=center,
    top color=white,
    bottom color=blue!20,
  },
  forked edges,
  [a
    [$ q_{1}k_{1} $
    [$ q_{2}k_{2} $
    [$ q_{3}k_{3} $]
    [$ \cdots $]
    [$ q_{3}k_{3} +(k_{3}-1)$]]
    [$ \cdots $]
    [$ q_{2}k_{2} +(k_{2}-1)$
        [$ q_{3}k_{3} $]
    [$ \cdots $]
    [$ q_{3}k_{3} +(k_{3}-1)$]
    ]]
    [$ \cdots $]
    [$ q_{1}k_{1} +(k_{1}-1)$
    [$ q_{2}k_{2} $
    [$ q_{3}k_{3} $]
    [$ \cdots $]
    [$ q_{3}k_{3} +(k_{3}-1)$]]
    [$ \cdots $]
    [$ q_{2}k_{2} +(k_{2}-1)$
[$ q_{3}k_{3} $]
    [$ \cdots $]
    [$ q_{3}k_{3} +(k_{3}-1)$]]    
    ]]

\end{forest}

我有两个问题

1- 这棵树不适合我的论文。

2-我怎样才能将带有...的盒子带到中间？

Answer 1

一种方法是将图旋转 90 度：

\documentclass{book}
\usepackage[edges]{forest}
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%
