条形图:更改不同图表和相应图例条目的垂直顺序

条形图:更改不同图表和相应图例条目的垂直顺序

我想使用水平条形图比较两个不同年份的百分比。

这两个年份(1996 年和 2011 年)的值是通过 pgfplots 表给出的。我希望 1996 年的值显示在相应的 2011 年值的顶部。但是,当按正确的顺序添加它们时,图例条目的顺序却相反(先显示 2011 年,然后显示 1996 年)。

梅威瑟:

\begin{document}

        ]
        \addplot table [x=1996, y=Type] {\data};
        \addplot table [x=2011, y=Type] {\data};
        \legend{1996,2011}
        \end{axis}
    \end{tikzpicture}

我尝试手动更改图例顺序,如下所述这个帖子,但这导致图例中的条形图和文本之间的垂直对齐变得丑陋:

\documentclass[a4paper,11pt,twoside]{memoir}
\usepackage{pgfplots}
\usepackage{pgfplotstable}

\begin{document}

\pgfplotstableread[col sep=comma,header=true]{
Type,1996,2011
type1,41.26,46.57
type2,55.42,38.76
type3,0.14,0.11
type4,0.24,0.05
type5,0.79,13.20
type6,2.14,1.31
}\data

\begin{figure} [tb]%
    \centering
    \begin{tikzpicture}     
        \begin{axis}[    
            width=12cm,
            xbar,                                 
            xtick={0,10,20,...,100},    
            xmin=0,
            xmax=100,       
            grid=major,
            nodes near coords, nodes near coords align={horizontal},
            symbolic y coords={type6,type5,type4,type3,type2,type1},
            ylabel={Type},
            xlabel={Percentage},
            y label style={at={(-0.1,0.5)}},
            enlarge x limits={abs=0},
            extra description/.code={
         \matrix[/pgfplots/every axis legend]
         {
                        \ref{1996} \pgfmatrixnextcell \node{1996};\\
                        \ref{2011} \pgfmatrixnextcell \node{2011};\\             
         };
         } 
        ]       
        \addplot table [x=2011, y=Type] {\data};        
        \label{2011}        
        \addplot table [x=1996, y=Type] {\data};
        \label{1996}
        \end{axis}
    \end{tikzpicture}
\label{fig:distribution}
\end{figure}

\end{document}

正如帖子中建议的那样,我查阅了tikz手册,但没有找到解决此问题的方法(至少对于我的乳胶技能而言)。有什么提示吗?

有一些键reverse legend可以精确地执行您想要的操作。

将其添加到选项列表中会产生

\documentclass[a4paper,11pt,twoside]{memoir}
\usepackage{pgfplots}
\usepackage{pgfplotstable}

\begin{document}
\thispagestyle{empty}

\pgfplotstableread[col sep=comma,header=true]{
Type,1996,2011
type1,41.26,46.57
type2,55.42,38.76
type3,0.14,0.11
type4,0.24,0.05
type5,0.79,13.20
type6,2.14,1.31
}\data

\begin{figure} [tb]%
    \centering
    \begin{tikzpicture}     
        \begin{axis}[    
            width=12cm,
            xbar,                                 
            xtick={0,10,20,...,100},    
            xmin=0,
            xmax=100,       
            grid=major,
            nodes near coords, nodes near coords align={horizontal},
            symbolic y coords={type6,type5,type4,type3,type2,type1},
            ylabel={Type},
            xlabel={Percentage},
            y label style={at={(-0.1,0.5)}},
            enlarge x limits={abs=0},
            reverse legend,
        ]
        \addplot table [x=2011, y=Type] {\data};
        \addplot table [x=1996, y=Type] {\data};
        \legend{2011,1996}
        \end{axis}
    \end{tikzpicture}
\label{fig:distribution}
\end{figure}

\end{document}
