电流输出

Question

我的文档中有很多 pgfplot，其中的曲线垂直穿过我想要 x 刻度标签的点。这使得这些标签难以阅读。

我确实希望这些标签仍然在那里。我在想，有没有办法将所有 x 刻度标签的背景颜色设为白色，以便在标签所在的曲线上留出一点空隙？

理想情况下，我希望将一些命令放在文档的开头，然后文档中的所有图表都会执行此操作。（而不是每个图表的命令。）

要填充刻度标签的背景，您可以使用ticklabel style={fill=white}。但它们是在绘图之前绘制的...要更改此顺序，您可以定义并使用新的图层集。

\pgfplotsset{
    standard/.style={
        axis x line=middle,
        axis y line=left,
        ticklabel style={fill=white},
        set layers=tick labels on top% use layers and choose the new layer set
    },
    layers/tick labels on top/.define layer set=% define the new layer set based on the standard one
        {axis background,axis grid,axis ticks,axis lines,main,%
          axis tick labels,% <- tick labels before main
          axis descriptions,axis foreground}
        {/pgfplots/layers/standard}
}

代码：

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.13}

\pgfplotsset{
    standard/.style={
        axis x line=middle,
        axis y line=left,
        ticklabel style={fill=white},
        set layers=tick labels on top% use layers and choose the new layer set
    },
    layers/tick labels on top/.define layer set=% define the new layer set based on the standard one
        {axis background,axis grid,axis ticks,axis lines,main,%
          axis tick labels,% <- tick labels before main
          axis descriptions,axis foreground}
        {/pgfplots/layers/standard}
}

\begin{document}
\begin{tikzpicture}[]
\begin{axis}[standard,
             domain=0:2,
             xtick={1},
             xticklabels={label},
             ] 
    \addplot[blue] 
    coordinates {
    (0,-1)
    (1,-1)
    (1,1)
    (2,1)
    }; 
\end{axis}
\end{tikzpicture}
\end{document}

将xticklabel style = {fill=white}和添加set layers = axis on top到轴上：

\documentclass{article}

\usepackage{pgfplots}
\pgfplotsset{compat=1.13}


\begin{document}

\pgfplotsset{
    standard/.style={
        axis x line=middle,
        axis y line=left,
        fill = blue
    }
}


\begin{tikzpicture}[]
\begin{axis}[standard,
             domain=0:2,
             xtick={1},
             xticklabels={label},
             xticklabel style = {fill=white},
             set layers = axis on top
             ] 
    \addplot[blue] 
    coordinates {
    (0,-1)
    (1,-1)
    (1,1)
    (2,1)
    }; 
\end{axis}
\end{tikzpicture}

您能否检查一下这是否有帮助：

    \begin{tikzpicture}[]
    \begin{axis}[standard,
                 domain=0:2,
                 xtick={1},
    %             xticklabels={label},
                 ] 
        \addplot[blue]
        coordinates {
        (0,-1)
        (1,-1)
        (1,1)
        (2,1)
        }; 
        \node[fill=white] at (axis description cs:.5,.445) {label};
    \end{axis}
    \end{tikzpicture}
