创建堆积和分组条形图

Question

我正在尝试制作分组堆叠条形图。我已经做到了这一点，代码如下。我的问题是应该有三个条形图组 - 但此代码似乎只生成了两个条形图组。此外，我需要两组标签 - 一组用于种族，一组用于世代，但不确定如何实现这一点，尤其是考虑到当前标签不起作用。任何帮助都感激不尽。

非常感谢，波莉

Answer 1

问题在于，你bar shift对两个axis环境使用了相同的值。例如，你想要-10pt一个环境使用 0 axis，下一个环境使用 0，10pt最后一个环境使用 0。

我可能还会添加hide axis前两个axis环境，以便轴框、刻度和刻度标签仅绘制一次。

\documentclass{article}    
\usepackage{pgfplots}
\pgfplotsset{compat=1.15}
\begin{document}
\begin{tikzpicture}[
  every axis/.style={ % add these settings to all the axis environments in the tikzpicture
    ybar stacked,
    ymin=0,ymax=11,
    x tick label style={rotate=45,anchor=east},
    symbolic x coords={
      White Other,
      African Caribbean and White,
      African,D,E
    },
  bar width=8pt
  },
]

% bar shift -10pt here
\begin{axis}[bar shift=-10pt,hide axis]
\addplot coordinates
{(White Other,1) (African Caribbean and White,1) (African,3) (D,2) (E,1.5)};
\addplot coordinates
{(White Other,1) (African Caribbean and White,1) (African,3) (D,2) (E,1.5)};
\addplot coordinates
{(White Other,1) (African Caribbean and White,1) (African,3) (D,2) (E,1.5)};
\end{axis}

% zero bar shift here    
\begin{axis}[hide axis]
\addplot+[fill=blue!50!gray] coordinates
{(White Other,1.5) (African Caribbean and White,1.5) (African,3.5) (D,2.5) 
(E,1)};
\addplot+[fill=red!50!gray] coordinates
{(White Other,1.5) (African Caribbean and White,1.5) (African,3.5) (D,2.5) 
(E,1)};
\addplot+[fill=yellow!50!gray] coordinates
{(White Other,1.5) (African Caribbean and White,1.5) (African,3.5) (D,2.5) 
(E,1)};
\end{axis}

% and bar shift +10pt here
\begin{axis}[bar shift=10pt]
\addplot+[fill=blue!50!gray] coordinates
{(White Other,1.5) (African Caribbean and White,1.5) (African,3.5) (D,2.5) 
(E,1)};
\addplot+[fill=red!50!gray] coordinates
{(White Other,1.5) (African Caribbean and White,1.5) (African,3.5) (D,2.5) 
(E,1)};
\addplot+[fill=yellow!50!gray] coordinates
{(White Other,1.5) (African Caribbean and White,1.5) (African,3.5) (D,2.5) 
(E,1)};
