How to make this rectangle a node (TikZ)?
You can specify the minimum height
and minimum width
for a node. In conjunction with draw
, you'll end up with a rectangle with the specified dimensions:
\node (rect) at (4,2) [draw,thick,minimum width=2cm,minimum height=2cm] {};
Another solution with fit
library. Following example shows how to use two opposite corner coordinates to define an rectangular node.
\documentclass[tikz,border=5]{standalone}
\usetikzlibrary{fit}
\begin{document}
\begin{tikzpicture}
\draw[help lines] (0,0) grid (6,4);
\fill[red] (3,1) circle (1pt) node[below left] {(3,1)} (5,3) circle (1pt) node[above right] {(5,3)};
\node[fit={(3,1) (5,3)}, inner sep=0pt, draw=blue, thick] (rect) {};
\draw[red] (rect.east) to[out=0,in=-90] (rect.south);
\end{tikzpicture}
\end{document}
You can define a node and put the rectagle inside. Then you can add more objets as nodes with relative posititions.
\documentclass[tikz,border=5]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}
\node(cuadrado){
\tikz {\draw[thick] (3,1) rectangle ++(2,2);}
};
%Text inside the rectangle
\node[at={($(cuadrado.center)$)},anchor=center] (texto) {asd asd asd};
\end{tikzpicture}
\end{document}
