TikZ 情節太冗長

我想知道是否有更簡潔的方式來表達以下情節（我使用的是普通格式）：

\input tikz
\tikzpicture
  \draw[help lines, ystep=.5] (-.2,-10) grid (12.5,15);
  \draw[->] (0, -10) to (0, 15) node[above] {$y$};
  \draw[->] (0, 0) to (12.5, 0) node[right] {$x$};
  \draw (1,-.5) node {$1$};
  \draw (2,-.5) node {$2$};
  \draw (3,-.5) node {$3$};
  \draw (4,-.5) node {$4$};
  \draw (5,-.5) node {$5$};
  \draw (6,-.5) node {$6$};
  \draw (7,-.5) node {$7$};
  \draw (8,-.5) node {$8$};
  \draw (9,-.5) node {$9$};
  \draw (10,-.5) node {$10$};
  \draw (11,-.5) node {$11$};
  \draw (12,-.5) node {$12$};

  \draw (-.5,-10) node {$-20$};
  \draw (-.5,-9) node {$-18$};
  \draw (-.5,-8) node {$-16$};
  \draw (-.5,-7) node {$-14$};
  \draw (-.5,-6) node {$-12$};
  \draw (-.5,-5) node {$-10$};
  \draw (-.5,-4) node {$-8$};
  \draw (-.5,-3) node {$-6$};
  \draw (-.5,-2) node {$-4$};
  \draw (-.5,-1) node {$-2$};
  \draw (-.5,0) node {$0$};
  \draw (-.5,1) node {$2$};
  \draw (-.5,2) node {$4$};
  \draw (-.5,3) node {$6$};
  \draw (-.5,4) node {$8$};
  \draw (-.5,5) node {$10$};

  \draw (0,-10) circle (2pt);
  \draw (1,-9) circle (2pt);
  \draw (2,-8) circle (2pt);
  \draw (3,-7) circle (2pt);
  \draw (4,-6) circle (2pt);
  \draw (5,-5) circle (2pt);
  \draw (6,-4) circle (2pt);
  \draw (7,-3) circle (2pt);
  \draw (8,-2) circle (2pt);
  \draw (9,-1) circle (2pt);
  \draw (10,0) circle (2pt);
  \draw (11,1) circle (2pt);
  \draw (12,2) circle (2pt);
\endtikzpicture
\bye

它太大了，無法放在一頁上。

這是一個 LaTeX 版本。

\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \draw[help lines, ystep=.5] (-.2,-10) grid (12.5,15);
  \draw[->] (0, -10) to (0, 15) node[above] {$y$};
  \draw[->] (0, 0) to (12.5, 0) node[right] {$x$};
  \foreach \X in {0,...,12}
  {\ifnum\X>0
  \node at (\X,-0.5) {$\X$};
  \fi
  \draw (\X,-10+\X) circle (2pt); }
  \foreach \Y in {-20,-18,...,10}
  {\node at (-0.5,\Y/2) {$\Y$};}
\end{tikzpicture}
\end{document}

令人驚訝的是，以下內容確實貫穿了pdftex

\input tikz
\tikzpicture
\draw[help lines, ystep=.5] (-.2,-10) grid (12.5,15);
  \draw[->] (0, -10) to (0, 15) node[above] {$y$};
  \draw[->] (0, 0) to (12.5, 0) node[right] {$x$};
  \foreach \X in {0,...,12}
  {\ifnum\X>0
  \node at (\X,-0.5) {$\X$};
  \fi
  \draw (\X,-10+\X) circle (2pt); }
  \foreach \Y in {-20,-18,...,10}
  {\node at (-0.5,\Y/2) {$\Y$};}
\endtikzpicture
\bye

因此，在花了一個晚上在試錯循環中閱讀手冊之後，在多次鄭重地說出召喚超自然力量對某物造成傷害或懲罰之後，所有這些現在都後悔了，我最終– 勝利– 形成了以下內容：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{datavisualization, datavisualization.formats.functions}
\begin{document}
\begin{tikzpicture}
  \datavisualization[
    school book axes
    , x axis={unit length=5mm}
    , y axis={
      unit length=5mm
      , ticks={step=2}
      , grid
      , scaling = min at 0cm and max at 5cm
    }
    , visualize as line
  ]
  data[format=function] {
    var x : interval [0:12];
    func y = (\value x - 10) * 2;
  };
\end{tikzpicture}
\end{document}

繁榮！噗！沙贊！神聖的函數資料格式，蝙蝠俠！這真是太好了，不得不說。

我發現的唯一麻煩是它不適用於純格式，迫使用戶下降到較低的啟蒙平面。
