Tikz add parenthesis to a tikzpicture

Question

I would like to add in my tikz picture a parenthesis like this :

I have already tried adding a \[\left( before and a \right)\] around the tikzpicture.

But it doesn't give the desired result:

Here's my code :

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{patterns}
\usetikzlibrary{decorations.pathreplacing,angles,quotes}
% defining the new dimensions and parameters
\newlength{\hatchspread}
\newlength{\hatchthickness}
\newlength{\hatchshift}
\newcommand{\hatchcolor}{}
% declaring the keys in tikz
\tikzset{hatchspread/.code={\setlength{\hatchspread}{#1}},
         hatchthickness/.code={\setlength{\hatchthickness}{#1}},
         hatchshift/.code={\setlength{\hatchshift}{#1}},% must be >= 0
         hatchcolor/.code={\renewcommand{\hatchcolor}{#1}}}
% setting the default values
\tikzset{hatchspread=10pt,
         hatchthickness=0.4pt,
         hatchshift=0pt,% must be >= 0
         hatchcolor=black}
% declaring the pattern
\pgfdeclarepatternformonly[\hatchspread,\hatchthickness,\hatchshift,\hatchcolor]% variables
   {custom north west lines}% name
   {\pgfqpoint{\dimexpr-2\hatchthickness}{\dimexpr-2\hatchthickness}}% lower left corner
   {\pgfqpoint{\dimexpr\hatchspread+2\hatchthickness}{\dimexpr\hatchspread+2\hatchthickness}}% upper right corner
   {\pgfqpoint{\dimexpr\hatchspread}{\dimexpr\hatchspread}}% tile size
   {% shape description
    \pgfsetlinewidth{\hatchthickness}
    \pgfpathmoveto{\pgfqpoint{0pt}{\dimexpr\hatchspread+\hatchshift}}
    \pgfpathlineto{\pgfqpoint{\dimexpr\hatchspread+0.15pt+\hatchshift}{-0.15pt}}
    \ifdim \hatchshift > 0pt
      \pgfpathmoveto{\pgfqpoint{0pt}{\hatchshift}}
      \pgfpathlineto{\pgfqpoint{\dimexpr0.15pt+\hatchshift}{-0.15pt}}
    \fi
    \pgfsetstrokecolor{\hatchcolor}
%    \pgfsetdash{{1pt}{1pt}}{0pt}% dashing cannot work correctly in all situation this way
    \pgfusepath{stroke}
   }
\begin{document}
\begin{center}
\begin{tikzpicture}
\draw fill=orange!50,draw=black rectangle (0.2,10);
\draw[pattern=custom north west lines] (0,6) rectangle (0.2,7);
\draw fill=orange!50,draw=black rectangle (0.2,6);
\draw fill=orange!50,draw=black rectangle (2.2,10);
\draw[pattern=custom north west lines] (2,6) rectangle (2.2,7);
\draw fill=orange!50,draw=black rectangle (2.2,6);
\draw fill=orange!50,draw=black rectangle (4.2,10);
\draw[pattern=custom north west lines] (4,6) rectangle (4.2,7);
\draw fill=orange!50,draw=black rectangle (4.2,6);
\end{tikzpicture}
\end{center}
\end{document}

Does anyone have an idea? Thank you in advance !

Answer 1

Define a suitable baseline of the picture. The parentheses \left(...\right) extend as far below the baseline as the object is high. Use e.g.

 \begin{tikzpicture}[baseline={(0,4.9)}]

For a pure tikz solution, see "draw round/rectangular bracket embracing nodes in tikz".
