填滿由多行界定的區域並添加文本

Question

我對 Tex 很陌生，正在嘗試使用 tikz 套件繪製圖表。

這是我寫的程式碼

\documentclass{article}
\usepackage{tikz}
\begin{document}
\ifx\du\undefined
  \newlength{\du}
\fi
\setlength{\du}{15\unitlength}
\begin{tikzpicture}
\pgftransformxscale{1}
\pgftransformyscale{-1}
\pgfsetlinewidth{0.1\du}
\draw (0\du,0\du)--(13\du,-13\du);
\draw (0\du,0\du)--(4\du,-1\du);
\draw (4\du,-1\du)--(9\du,-5\du);
\draw (9\du,-5\du)--(11\du,-8\du);
\draw (11\du,-8\du)--(13\du,-13\du);
\node[anchor=west] at (7\du,-5\du){some text};
\end{tikzpicture}
\end{document}

我試圖填充這些線所包圍的區域，並且讓“一些文字”可見。

有人可以幫忙嗎？

Answer 1

正如我可以理解你在尋找什麼，這裡有一個解決方案，擺脫這些不需要的低級 pgf 線並相應地修改 y 坐標以避免這種情況y 變換形狀。

\documentclass{article}
\usepackage{tikz}
\begin{document}
    \ifx\du\undefined
      \newlength{\du}
    \fi
    \setlength{\du}{15\unitlength}
    \begin{tikzpicture}
        \draw[line width=0.1\du, fill=pink] (0\du,0\du)--(13\du,13\du) -- (11\du,8\du) -- (9\du,5\du) -- (4\du,1\du) -- cycle;
        \node at (7\du,5\du){some text};
    \end{tikzpicture}
\end{document}

Answer 2

\documentclass[tikz, border=1cm]{standalone}
\begin{document}
\begin{tikzpicture}
\newcommand{\du}{15pt}
\draw[fill=cyan,very thick] (0,0) -- (13*\du,13*\du) -- (11*\du,8*\du) -- (9*\du,5*\du)  -- (4*\du,\du) -- cycle;
\node[anchor=west, red, font=\large] at (7*\du,5*\du){some text};
\end{tikzpicture}
\end{document}
