我有多个条形图，我想对齐它们，以便所有条形图都从同一点开始 - 我该如何实现这一点？

编辑：我忘了提的一件事是，中间还有其他元素。我相应地编辑了 MWE。也许是为了更清楚：它用于显示问卷的结果。因此格式是标题 -> 枚举列表 -> 标题 -> 图表 -> 标题 -> 枚举列表 -> 标题 -> 图表等等

我想要的是：

左边的红线是开始\textwidth，右边的红线表示对齐

我拥有的：

\documentclass{article} 
\usepackage{pgfplots}
\pgfplotsset{
   compat=newest,
   axispower/.style={
    xbar,
    y axis line style={ opacity=0 },
    axis x line=none,
    tickwidth=0pt,
    xmin=0,
    y=20pt,
    nodes near coords,
    bar shift=0pt,
    ytick=data
  }
}
\begin{document}

\subsubsection{Notification-System} \label{results1}
\begin{tikzpicture}
  \begin{axis}[axispower, symbolic y coords={Chat,E-Mail,SMS,Web}]
  \addplot coordinates {(68,Web)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{axis}
\end{tikzpicture}

\vspace{1cm}

\subsubsection{Notification-System 2} \label{results2}
\begin{tikzpicture}
  \begin{axis}[axispower, symbolic y coords={Chat,E-Mail,SMS,Web-Notification}]
  \addplot coordinates {(68,Web-Notification)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{axis}
\end{tikzpicture}

\end{document}

答案1

您可以更改标签的样式，使得它们的最小宽度都大于最大宽度。

 yticklabel style={text width=28mm,align=right},

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

\newcommand{\axispower}{
    xbar,
    y axis line style={ opacity=0 },
    axis x line=none,
    yticklabel style={text width=28mm,align=right},
    tickwidth=0pt,
    xmin=0,
    y=20pt,
    nodes near coords,
    bar shift=0pt
}
\begin{document}

\begin{tikzpicture}
  \begin{axis}[\axispower, symbolic y coords={Chat,E-Mail,SMS,Web,Web-Notification}]
  \addplot coordinates {(68,Web)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{axis}

  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{axis}
\end{tikzpicture}

你可以把它们放在同一个tikzpicture环境中。第二个axis环境低几厘米，这里是 3.5 厘米。

%\begin{tikzpicture}
  \begin{axis}[\axispower, symbolic y coords={Chat,E-Mail,SMS,Web-Notification},yshift=-3.5cm]

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

\newcommand{\axispower}{
    xbar,
    y axis line style={ opacity=0 },
    axis x line=none,
    tickwidth=0pt,
    xmin=0,
    y=20pt,
    nodes near coords,
    bar shift=0pt
}
\begin{document}

\begin{tikzpicture}
  \begin{axis}[\axispower, symbolic y coords={Chat,E-Mail,SMS,Web},local bounding box=premiere]
  \addplot coordinates {(68,Web)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};

答案2

快速解决方法是使用

\hspace{3cm}\begin{tikzpicture}[trim axis left]

对于两个tikzpictures，trim axis left设置 的边界框tikzpicture，使其左边缘位于 的左边缘axis，不包括标签。水平空间用于确保标签不会进入左边距。

  \addplot coordinates {(52,Chat)};

环境groupplot（来自pgfplots库groupplots）适用于需要在网格中对齐多个轴的情况，这基本上就是您在此处所做的。它相当简单，使用环境groupplot而不是axis，使用设置网格中的行数和列数group style={group size=1 by 2}（在这里您还可以设置轴之间的空间和其他内容），axis然后添加常用选项。使用开始每个新轴\nextgroupplot[<local settings for this axis>]。

在下面的代码中，我还创建了axispower一种样式而不是宏，我认为这更有意义。

\documentclass{article} 
\usepackage{pgfplots,showframe}
\usepgfplotslibrary{groupplots}
\pgfplotsset{
   compat=newest,
   axispower/.style={
    xbar,
    y axis line style={ opacity=0 },
    axis x line=none,
    tickwidth=0pt,
    xmin=0,
    y=20pt,
    nodes near coords,
    bar shift=0pt,
  }
}
\begin{document}

\begin{tikzpicture}
  \begin{groupplot}[
     group style={group size=1 by 2},
     axispower
]

\nextgroupplot[symbolic y coords={Chat,E-Mail,SMS,Web}]
  \addplot coordinates {(68,Web)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};

\nextgroupplot[symbolic y coords={Chat,E-Mail,SMS,Web-Notification}]
  \addplot coordinates {(68,Web-Notification)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{groupplot}
\end{tikzpicture}

\end{document}

另一个可能的解决方案：将两者放在axis一个tikzpicture环境中并使用anchor选项来对齐它们。

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

\newcommand{\axispower}{
    xbar,
    y axis line style={ opacity=0 },
    axis x line=none,
    tickwidth=0pt,
    xmin=0,
    y=20pt,
    nodes near coords,
    bar shift=0pt
}

\begin{document}

\begin{tikzpicture}
  \begin{axis}
  [\axispower,
   symbolic y coords={Chat,E-Mail,SMS,Web},
   name=top plot,]
  \addplot coordinates {(68,Web)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{axis}
%\end{tikzpicture}

%\vspace{1cm}

%\begin{tikzpicture}
  \begin{axis}[
  \axispower, 
  symbolic y coords={Chat,E-Mail,SMS,Web-Notification},
  anchor=north west,
  at={(top plot.below south west)},
  yshift=-5mm]
  \addplot coordinates {(68,Web-Notification)};
  \addplot coordinates {(22,SMS)};
  \addplot coordinates {(50,E-Mail)};
  \addplot coordinates {(52,Chat)};
  \end{axis}
\end{tikzpicture}

\end{document}
