如何使用 pgfplots 设置列宽和列间距

Question

该代码运行正常，但我想使列更大并且它们之间的空间更小，我该如何使用来实现呢pgfplots？

\begin{tikzpicture}
\begin{axis}[
    ybar,
    legend style={at={(0.5,-0.15)},
      anchor=north,legend columns=-1},
    ylabel={\#Percentage},
    symbolic x coords={Slow,Medium,Fast},
    xtick=data,
    ymin=0,ymax=100,
    nodes near coords,
    nodes near coords align={vertical},
    ]
\addplot coordinates {(Slow,90.7) (Medium,89.3) (Fast,93.7)};
\addplot coordinates {(Slow,39.7) (Medium,43.3) (Fast,39.6)};
\legend{Messages received,Messages retransmitted}
\end{axis}
\end{tikzpicture}

您可以使用 增加条形的宽度bar width。此外，我认为您需要enlarge x limits避免条形被剪切。

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
    ybar,
    bar width=25,enlarge x limits=0.25, %  <--- added
    legend style={at={(0.5,-0.15)},
      anchor=north,legend columns=-1},
    ylabel={\#Percentage},
    symbolic x coords={Slow,Medium,Fast},
    xtick=data,
    ymin=0,ymax=100,
    nodes near coords,
    nodes near coords align={vertical},
    ]
\addplot coordinates {(Slow,90.7) (Medium,89.3) (Fast,93.7)};
\addplot coordinates {(Slow,39.7) (Medium,43.3) (Fast,39.6)};
\legend{Messages received,Messages retransmitted}
\end{axis}
\end{tikzpicture}
\end{document}
