答案1
以下是我的评论,我的版本如下:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{center}
\begin{tikzpicture}[scale=.5,arr/.style={line width=1pt,blue,Bar-Bar}]
\foreach \i/\x in
{
1/1,
2/3,
3/4,
4/7,
5/9,
6/11,
7/13,
8/15,
9/20,
10/21,
11/23,
12/27
}
{
\coordinate (p_\i) at (\x,0);
\filldraw (p_\i) circle (2pt) node[below=2pt] {$p_{\i}$};
}
\draw (0,0) -- (28,0);
\path (0,0) -- (0,10); %just to avoid the `transform canvas` option to get your drawings out of the page
\begin{scope}[arr,every path/.style={transform canvas={shift={(0,1)}}}]
\draw (p_1) -- (p_2);
\draw (p_3) -- (p_4);
\draw (p_11) -- (p_12);
\end{scope}
\begin{scope}[arr,every path/.style={transform canvas={shift={(0,2)}}}]
\draw (p_2) -- (p_4);
\draw (p_5) -- (p_7);
\draw (p_10) -- (p_11);
\end{scope}
\begin{scope}[arr,every path/.style={transform canvas={shift={(0,4)}}}]
\draw (p_1) -- (p_3);
\draw (p_4) -- (p_5);
\draw (p_6) -- (p_7);
\draw (p_9) -- (p_11);
\end{scope}
\end{tikzpicture}
\end{center}
\end{document}
您只需调整 p_1 到 p_12 的坐标,其余的就会随之调整。该transform canvas
选项旨在允许您在 p_i 节点之间移动路径,并避免手动实现每个段的坐标。
答案2
从这里开始,剩下的就是输入数字:
\documentclass[tikz, border=3.5mm]{standalone}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[arr/.style={Bar-Bar}]
%baseline
\draw[] (0,-0) -- (4,0);
%nodes
\draw[] (0,-0.1) -- (0,0.1);
\node[scale=0.2] at (0,-0.2) {P1};
\draw[] (1,-0.1) -- (1,0.1);
\node[scale=0.2] at (1,-0.2) {P2};
\draw[] (2,-0.1) -- (2,0.1);
\node[scale=0.2] at (2,-0.2) {P3};
%arrows
\draw[arr] (0,0.5) -- (1,0.5);
\draw[arr] (1,1) -- (2,1);
%EDIT: red dashed line
\draw[red,dashed] (0.5,0) -- (0.5,1);
\draw[red,dashed] (1.5,0.5) -- (1.5,1.5);
\end{tikzpicture}
\end{document}
