ymajorgrids 打印在区域样式上

Question

这是我的 MWE：

\documentclass{article}
\usepackage{pgfplots}
\begin{document}

\begin{tikzpicture}
\begin{axis}[
    area style,
    ymajorgrids=true,
    bar width=0.6cm
    ]

\addplot+[ybar interval, mark=no, fill=black!20, draw=black!40] coordinates{(0.0,1) (0.75,1) 
(0.75,1) (1.5,1) 
(1.5,1) (2.25,1) 
(2.25,0) (3.0,0) 
(3.0,0) (3.75,0) 
(3.75,2) (4.5,2) 
(4.5,1) (5.25,1) 
};
\end{axis}
\end{tikzpicture}

\end{document}

正如您在下面看到的，这些线条ymajorgrids位于我绘图的“条”上方。

有没有什么办法可以防止这种情况发生？

谢谢

这是因为area legend样式设置了axis on top。要获得所需结果，只需将其删除并重命名mark=no为mark=none。
