pgfplot - 垂直网格线越过轴

无论出于什么原因，在这个 pgfplot 中，垂直网格线与轴重叠（看起来很丑），尽管我在另一个网格线不重叠的图中使用了非常相似的轴。它看起来像这样：

最小工作示例：

\documentclass[a4paper,12pt]{report}

\usepackage{float}
\usepackage{tikz}
\usepackage{pgf}
\usepackage{pgfplots, pgfplotstable}

      \end{tikzpicture}

数据socket_ltncy_30s_recvmsg_8x1080p50_24g.csv看起来像这样

我希望它们向内“弯曲”，像这样：

这不是网格线，而是刻度。添加tick align=inside到axis选项中，后选项ybar。（ybar似乎设置了xtick align=outside，因此您需要覆盖该设置。）

不相关的旁注：pgfplots加载tikz，因此也pgf加载 ，因此当您有 时，您无需明确加载后两者pgfplots。我认为，环境\centering中的tikzpicture实际上不做任何事情，因此您可以将其删除。

最小示例：

\documentclass{report}
\usepackage{pgfplots}
\begin{document}
    \begin{tikzpicture}
        \begin{axis}[
            ybar,
            %tick align=inside % uncomment this to see difference
            ]
            \addplot {rnd};
        \end{axis}
      \end{tikzpicture}
\end{document}
