tikzpic 的兩條時間線？

Question

我正在嘗試使用 tikzpicture 建立兩個時間軸。上面的一張看起來像我想要的，但我在下面的一張上遇到了麻煩。我不再產生小的垂直刻度線，而是產生大的對角線。

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{snakes}
\usepackage{fullpage}
\usepackage{graphicx}


\begin{document}
\resizebox{\linewidth}{!}{% Resize table to fit within
\begin{tikzpicture}[snake=zigzag, line before snake = 5mm, line after snake = 5mm]
%draw horizontal line
\draw (0,0) -- (19/2,0);
\draw[snake] (19/2,0) -- (25/2,0);
\draw (25/2,0) -- (30/2,0);
\draw[snake] (30/2,0) -- (35/2,0);
\draw (35/2,0) -- (40/2,0);
%draw vertical lines
\foreach \x in {0, 5, 10, 19, 30, 40}{
   \draw (\x/2,3pt) -- (\x/2,-3pt);
}
%draw nodes
\draw (-2,0) node { PHYS1060 };

\draw (0,0) node[below=3pt] { Pre-test published } node[above=3pt] { Jan 4, 2014  };
\draw (5/2,0) node[below=3pt] { Nudge } node[above=3pt] { Jan 9, 2014  };
\draw (10/2,0) node[below=3pt] { First class } node[above=3pt] { Jan 13, 2014  };
\draw (19/2,0) node[below=3pt] { Pre-test due } node[above=3pt] { Jan 22, 2014  };
\draw (30/2,0) node[below=3pt] { Midterm } node[above=3pt] { Feb 17, 2014  };
\draw (40/2,0) node[below=3pt] { Final Exam} node[above=3pt] { May 5, 2014  };


%draw horizontal line
\draw (-2,-2) node { PHYS1050 };
\draw (0,-2) -- (19/2,-2);
\draw[snake] (19/2,-2) -- (25/2,-2);
\draw (25/2,-2) -- (30/2,-2);
\draw[snake] (30/2,-2) -- (35/2,-2);
\draw (35/2,-2) -- (40/2,-2);
draw vertical lines
\foreach \x in {0, 5, 10, 19, 30, 40}{
   \draw (\x/2,-2,3pt) -- (\x/2,-2,-3pt);
}


%draw nodes
\draw (0,-2) node[below=3pt] { Pre-test published } node[above=3pt] { Aug 10, 2014  };
\draw (5/2,-2) node[below=3pt] { First class } node[above=3pt] { Aug 27, 2014  };
\draw (10/2,-2) node[below=3pt] { Nudge } node[above=3pt] { Sept 4, 2014  };
\draw (19/2,-2) node[below=3pt] { Pre-test due } node[above=3pt] { Sept 7, 2014  };
\draw (30/2,-2) node[below=3pt] { Midterm } node[above=3pt] { ?, 2014  };
\draw (40/2,-2) node[below=3pt] { Final Exam} node[above=3pt] { ?, 2014  };

\end{tikzpicture}
}

\end{document}

我做錯了什麼以及如何解決它？

謝謝！

Answer 1

我會明確定義垂直線的座標。

所以你的第一條垂直線將變成：

\foreach \x in {0, 5, 10, 19, 30, 40}{
   \draw (\x/2,-0.2) -- (\x/2,0.2);
}

第二組是

\foreach \x in {0, 5, 10, 19, 30, 40}{
   \draw (\x/2,-2.2) -- (\x/2,-1.8);
}

Answer 2

第二種情況下垂直線 y 座標的計算是錯誤的。在第一種情況下它有效，因為水平線位於 height 0。在第二種情況下，您必須新增 offset -2，這可以透過calc-library 來實現。
