如何调整此条形图的元素？

我有以下 MWE：

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}

\pgfplotsset{compat=1.11,
    /pgfplots/ybar legend/.style={
        /pgfplots/legend image code/.code={%
            \draw[##1,/tikz/.cd,yshift=-0.25em]
            (0cm,0cm) rectangle (0.8em,0.8em);},
    },
}

\begin{document}


\begin{tikzpicture}
\scriptsize
\begin{axis}[
ybar, bar width = 0.2cm,
axis lines=left, 
enlargelimits = 0.15,
% y and x axis ticks
y tick label style={/pgf/number format/.cd, fixed, fixed zerofill,precision=1,/tikz/.cd},
ymin = 0.0,
xtick=data,
x tick label style={rotate = 90},
symbolic x coords={US, Euro, UK, PR China, Singapore, Indonesia, Malaysia, Korea, Taiwan, Philippines},
% legends and labels
legend style={at={(0.5, 0.9)},anchor=north},
ylabel={Annual change (\%)},
y label style={at={(axis description cs:0.15,1)},rotate=-90,anchor=south},
% data labels
nodes near coords,
nodes near coords style={/pgf/number format/.cd, fixed, fixed zerofill,precision=1,/tikz/.cd},
]
\addplot[red, fill = red] coordinates {(US,2.0) (Euro,1.2) (UK,1.2) (PR China,6.1) (Singapore,0.2) (Indonesia,5.1) (Malaysia,4.7) (Korea, 2.1) (Taiwan, 1.7) (Philippines,5.6)};
\addplot[green!20!black, fill = green!20!black] coordinates {(US,1.9) (Euro,1.1) (UK,1.0) (PR China,6.0) (Singapore,0.1) (Indonesia,5.0) (Malaysia,4.4) (Korea,2.0) (Taiwan,2.9) (Philippines,5.9)};
%\addplot[red, fill = red] coordinates {(US,2.0) (Euro,1.2) (UK,1.2) (China,6.1)};
%\addplot[green!20!black, fill = green!20!black] coordinates {(US,1.9) (Euro,1.1) (UK,1.0) (China,6.0)};
\legend{\phantom{a}2Q19, \phantom{a}3Q19}
\end{axis}
\end{tikzpicture}

\end{document}

结果是：

大多数调整我都能够找到方法。但有 3 个调整让我很纠结：

  1. 如何删除 0 以下的 y 轴空间？尽管我声明了，但它仍然从 -0.5 开始ymin = 0.0。
  2. 如何删除红色条上的所有数据标签？我只想调出 2019 年第三季度系列的数据（黑色条）。

答案1

  1. 这enlargelimits=0.15是在数据下方和数据左侧添加额外空间。通过设置enlargelimits=false然后enlarge x limits=0.15您可以修复轴问题。
  2. 正在nodes near coords为两个数据系列创建标签。在下面的解决方案中，我已将其从 的选项中删除axis，并将其添加到 的选项中\addplot。

最终的代码如下：

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}

\pgfplotsset{compat=1.11,
    /pgfplots/ybar legend/.style={
        /pgfplots/legend image code/.code={%
            \draw[##1,/tikz/.cd,yshift=-0.25em]
            (0cm,0cm) rectangle (0.8em,0.8em);},
    },
}

\begin{document}


\begin{tikzpicture}
\scriptsize
\begin{axis}[
ybar, bar width = 0.2cm,
axis lines=left, 
enlargelimits=false,
enlarge x limits=0.15,
% y and x axis ticks
y tick label style={/pgf/number format/.cd, fixed, fixed zerofill,precision=1,/tikz/.cd},
ymin = 0.0,
xtick=data,
x tick label style={rotate = 90},
symbolic x coords={US, Euro, UK, PR China, Singapore, Indonesia, Malaysia, Korea, Taiwan, Philippines},
% legends and labels
legend style={at={(0.5, 0.9)},anchor=north},
ylabel={Annual change (\%)},
y label style={at={(axis description cs:0.15,1)},rotate=-90,anchor=south},
nodes near coords style={/pgf/number format/.cd, fixed, fixed zerofill,precision=1,/tikz/.cd},
]
\addplot[red, fill = red] coordinates {(US,2.0) (Euro,1.2) (UK,1.2) (PR China,6.1) (Singapore,0.2) (Indonesia,5.1) (Malaysia,4.7) (Korea, 2.1) (Taiwan, 1.7) (Philippines,5.6)};
\addplot[green!20!black, fill = green!20!black, nodes near coords] coordinates {(US,1.9) (Euro,1.1) (UK,1.0) (PR China,6.0) (Singapore,0.1) (Indonesia,5.0) (Malaysia,4.4) (Korea,2.0) (Taiwan,2.9) (Philippines,5.9)};
%\addplot[red, fill = red] coordinates {(US,2.0) (Euro,1.2) (UK,1.2) (China,6.1)};
%\addplot[green!20!black, fill = green!20!black] coordinates {(US,1.9) (Euro,1.1) (UK,1.0) (China,6.0)};
\legend{\phantom{a}2Q19, \phantom{a}3Q19}
\end{axis}
\end{tikzpicture}

\end{document}

对我来说，编译如下。请注意，这看起来不太像您的屏幕截图，我怀疑是因为您的屏幕截图不是 MWE 的屏幕截图，而是来自原始文件的屏幕截图，其中包含一些其他设置。
