在多个水平堆叠条形图中显示百分比

Question

我需要在每个单元格中显示百分比而不是实际数字。最大值是 106。请帮帮我。问候

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}

\begin{document}
\begin{tikzpicture}
  \begin{axis}[
      xbar stacked,
      width=15.6cm, height=6.0cm, 
      bar width=15pt,
      nodes near coords,
      xmin=0, xmax=106,
      %enlargelimits=0.15,
      %enlarge y limits=0.01,
      %enlargelimits=0.07,
      legend style={at={(0.5,-0.20)}, anchor=north, legend columns=-1},
      %ylabel={\#participants},
      symbolic y coords={A, B, C, D, E},
      ytick=data,
    ]
      \addplot coordinates {(54,A) (49,B) (42,C) (41,D) (37,E)};
      \addplot coordinates {(3,A) (7,B) (1,C) (7,D) (16,E)};
      \addplot coordinates {(34,A) (28,B) (50,C) (43,D) (30,E)};
      \addplot coordinates {(12,A) (20,B) (9,C) (11,D) (19,E)};
      \addplot[color=violet, fill=violet!50] coordinates {(3,A) (2,B) (4,C) (4,D) (4,E)};
      \legend{\strut Agree, \strut Strongly agree, \strut neutral, \strut Disagree, \strut Strongly disagree}
  \end{axis}
\end{tikzpicture}
\end{document}

Answer 1

• 用于nodes near coords={...}自定义坐标附近的节点的内容。
• 用于\pgfmathprintnumber[fixed, precision=1]{...}获取精度为 1 的固定数字。
• nodes near coords custom当空间不足时，我也会用它来移动节点。
• 用于xticklabel={...}改变 x 标签的显示样式，方法与nodes near coords={...}
