是否可以复制这张精确的 jpg 图像？

Question

我的问题是关于在乳胶中创建这棵精确的树。

我尝试了几种方法，但没有结果。

我的代码如下

\documentclass[a4paper,12pt,twosided]{book}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{tikz}
\begin{document}


\begin{tikzpicture}[sibling distance=9em,
every node/.style = {shape=rectangle, rounded corners,
    draw, align=center,
    top color=white, bottom color=blue!20}]]
\node {Numri i firmave ?}[a]
child { node {1 firm\"e} 
    child { node {} 
        child {node{monopol}}}}
child { node {Pak firma} 
    child {node {}
        child {node {oligopol}}}
}
child { node {Shum\"e firma}
    child { node {lloji i produktit}
        child{node {konk monop}}
        child{node {konk e plt}
}}};


\end{tikzpicture}
\end{document}

Answer 1

你的MWE和你的图不完全一样，我遵循的是前者。

\documentclass[a4paper,12pt,twosided]{book}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{tikz}
\usetikzlibrary{positioning}

\begin{document}
\begin{figure}[ht]
    \centering
\begin{tikzpicture}[
    sibling distance=10em,
    mynode/.style = {
            shape=rectangle,         rounded corners,
            draw, align=center,
            top color=white, bottom color=blue!20
            },
    myquest/.style = {shape=rectangle,        draw, align=center,
        fill=blue!20},
    ]
    \node[myquest] {Numri i firmave ?}
        child { node[mynode, yshift=-4em] (monop) {monopol}
            edge from parent
                node[left=16pt] {1 firm\"e} 
            }
        child {node[mynode, right=of monop] (olig){oligopol} edge from parent node[right] {Pak firma}}
        child {  
        node[myquest] {lloji i produktit}
            child{node[mynode, right=of olig] (monocomp) {konk monop}}
            child{node[mynode, right=of monocomp] {konk e plt}}
        edge from parent node[above right] {Shum\"e firma}
     };
\end{tikzpicture}

\end{figure}
