将矩阵水平放置在中心

Question

我想将树定位在页面的北中心，但出于某种原因，前进的 x 坐标不会改变任何东西。使用相对定位在中node-0绘制也无济于事。node-0current page.north

有谁知道这里可能出了什么问题？

\begin{tikzpicture} [    
    array/.style = { 
        matrix of nodes, 
        nodes = { draw, minimum size = 7mm, anchor = center, fill = violet!30 },         
        nodes in empty cells        
    },    
    edge/.style = { -> }    
] 
    \matrix[array] (node-0) at (14, 0) { 0 & 1 & 2 & 3 \\ };
    \matrix[array] (node-1) [below left=0.4cm and 0.4cm of node-0] { 0 & 1 & 2 & 3 \\ };
    \matrix[array] (node-2) [below right=0.4cm and 0.4cm of node-0] { 0 & 1 & & \\ };

    \draw[edge] (node-0-1-1.south) to (node-1.north);
    \draw[edge] (node-0-1-2.south) to (node-2.north);    
\end{tikzpicture}

请尝试以下操作

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{matrix, positioning}

\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}[
array/.style = {
matrix of nodes,
nodes = { draw, minimum size = 7mm, anchor = center, fill = violet!30 },
nodes in empty cells
},
edge/.style = { -> }
]
\matrix[array] (node-0) at (14, 0) { 0 & 1 & 2 & 3 \\ };
\matrix[array] (node-1) [below left=0.4cm and 0.4cm of node-0] { 0 & 1 & 2 & 3 \\ };
\matrix[array] (node-2) [below right=0.4cm and 0.4cm of node-0] { 0 & 1 & & \\ };

\draw[edge] (node-0-1-1.south) to (node-1.north);
\draw[edge] (node-0-1-2.south) to (node-2.north);    
\end{tikzpicture}
\end{figure}

\end{document}
