我创建了一个情节普格夫并尝试按照我想要的方式设计它。为此，我选择在块外添加标签和文本axis，因为我想创建几个节点来解释情节。
该axis块已经具有选项width、height和/bar/width以及cm值。但是指定的值使用不正确。到目前为止，我只能使整个图的宽度达到所需的宽度。我添加了一些线条作为指导以使其清晰。
脚本如下：
\documentclass[tikz, 12pt, a4paper]{article}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
ybar stacked,
width = 5cm,
height = 8cm,
y axis line style = { opacity = 0 },
axis x line = none,
ytick=\empty,
ymin = 0,
scale only axis=true,
bar width=2cm,
symbolic x coords = {2016,2017},
every axis plot/.append style={
fill
}]
\addplot[red] coordinates {(2017,47.4) (2016,43.9)};
\addplot[blue] coordinates {(2017,6.8) (2016,6.3)};
\addplot[green] coordinates {(2017,18.5) (2016,17.6)};
\addplot[orange] coordinates {(2017,5.4) (2016,5.2)};
\end{axis}
\draw (0,0) -- (5cm,0) -- (5cm,8cm); % The desired space of entire plot
\draw (2cm,0) -- (2cm,8cm); % and the right edge of first bar
\draw (3cm,0) -- (3cm,8cm); % and the left edge of second bar
\begin{scope}[xshift=-2cm,yshift=-0.8cm]
\draw[line width=3mm,red] (0,0) -- ++(0:3mm) node[right, black, align=left] {\footnotesize Lorem Ipsum};
\draw[line width=3mm,blue] (4,0) -- ++(0:3mm) node[right, black, align=left] {\footnotesize Consetetur Sadipscing};
\draw[line width=3mm,green] (0,-0.6) -- ++(0:3mm) node[right, black, align=left] {\footnotesize Magna Aliquyam};
\draw[line width=3mm,orange] (4,-0.6) -- ++(0:3mm) node[right, black, align=left] {\footnotesize Diam Nonumy Eirmod Tempor};
\end{scope}
\end{tikzpicture}
\end{document}
我怎样才能让条形达到我想要的精确宽度？
答案1
这不是一个太严肃的答案，而只是bar width=pi*1cm似乎给了你想要的东西的观察。;-)（可以通过设置来去除垂直多余的部分ymax，所以这更为严重。我想你知道人们可以用不同的方式创造传奇。）
