![在箱线图上将 x 轴数字更改为不同的值,](https://linux22.com/image/416790/%E5%9C%A8%E7%AE%B1%E7%BA%BF%E5%9B%BE%E4%B8%8A%E5%B0%86%20x%20%E8%BD%B4%E6%95%B0%E5%AD%97%E6%9B%B4%E6%94%B9%E4%B8%BA%E4%B8%8D%E5%90%8C%E7%9A%84%E5%80%BC%EF%BC%8C.png)
我必须创建多个箱形图,如下所示,这是我从将数字添加到蛇形图(箱线图)。
我想将轴的开始和结束值更改为不同的值,例如开始12
完成23
,这样我就可以将它们提供给我的学生,他们会给我五点总结。
我更改了值以获取最后一个刻度。我可以通过更改所有值来创建新的箱线图,但这非常耗时。

答案1
通过在循环中添加新计数器,\foreach
您可以将刻度位置的计数器和刻度的值分开:
\documentclass[]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{pgfplots}
\usepgfplotslibrary{statistics}
\pgfplotsset{compat=1.16}
\usetikzlibrary{snakes,arrows,backgrounds,decorations.pathreplacing}
\begin{document}
\begin{tikzpicture} [thick, framed]
\filldraw[fill=green!20] (2.85,0) rectangle (5.7,1);
\draw (4.45,0)--(4.45,1);
\draw (5.7,0.5)--(11,0.5);%vandret linie til max
\draw (2.85,0.5)--(1,0.5);%vandret linie til min
\draw (11,0.39)--(11,0.61);
\draw (1,0.39)--(1,0.61);
\draw [
postaction={
draw,
decoration=ticks,
segment length=1cm, % this changes number of ticks
decorate,
}
] (0,-1) -- (11.005,-1); % 11.005 need for last tick
\foreach \tick [count=\x from 0] in {12,...,23} % <----
\node at (\x,-1) [below=1pt] {\tick}; % <----
\end{tikzpicture}
\end{document}
答案2
另一个选择boxplot
是pgfplots
。
\documentclass[]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{pgfplots}
\usetikzlibrary{backgrounds}
\usepgfplotslibrary{statistics}
\pgfplotsset{compat=1.16}
\begin{document}
\begin{tikzpicture}[show background rectangle]
\begin{axis}[
axis x line=bottom,
axis x line shift=5mm,
axis y line=none,
y=1cm,
xtick distance=1,
xmin=-0.2, xmax=12.4,
]
\addplot+ [
fill=green!20, draw=black,
boxplot prepared={
lower whisker=1, lower quartile=2.85,
median=4.45,
upper quartile=5.7, upper whisker=11,
},
] coordinates {};
\end{axis}
\end{tikzpicture}
\par
\vspace{1cm}
\begin{tikzpicture}[show background rectangle]
\begin{axis}[
axis x line=bottom,
axis x line shift=5mm,
axis y line=none,
y=1cm,
xtick distance=1,

]
\addplot+ [
fill=red!20, draw=black,
boxplot prepared={

\end{tikzpicture}
