删除轴和矩阵图之间的边距

在以下 MWE 中，如何删除矩阵和轴之间的边距（红色箭头）？

\documentclass[margin=1cm]{standalone}

\usepackage{pgfplots}
\usetikzlibrary{3d}

\pgfplotsset{compat=1.14}

\begin{document}
    \begin{tikzpicture}

    \begin{axis}[%
    enlargelimits=false,
    axis equal,
    scale only axis,
    nodes near coords={\pgfmathprintnumber\pgfplotspointmeta},
    every node near coord/.append style={xshift=0pt,yshift=-7pt, black, font=\scriptsize},
    ytick=\empty,
    xtick=\empty
    ]

    \addplot[
    matrix plot*,
    point meta=explicit]
    table[meta=C]{
        x y C
0 0 0.0
0 1 0.0
0 2 0.3

1 0 0.0
1 1 1.0
1 2 0.0

2 0 0.0
2 1 0.0
2 2 .7
    };
    \end{axis}
    \end{tikzpicture}
\end{document}

以下是使用 Ti 调整边界框的一种方法钾Z 方法。不过我不确定这是否是你想要的。

\documentclass[margin=0.5cm]{standalone}

\usepackage{pgfplots}

\pgfplotsset{compat=1.16}

\begin{document}
    \begin{tikzpicture}
    \begin{pgfinterruptboundingbox}
    \begin{axis}[%
    enlargelimits=false,
    axis equal,
    scale only axis,
    nodes near coords={\pgfmathprintnumber\pgfplotspointmeta},
    every node near coord/.append style={xshift=0pt,yshift=-7pt, black, font=\scriptsize},
    ytick=\empty,
    xtick=\empty
    ]

    \addplot[
    matrix plot*,
    point meta=explicit]
    table[meta=C]{
        x y C
0 0 0.0
0 1 0.0
0 2 0.3

1 0 0.0
1 1 1.0
1 2 0.0

2 0 0.0
2 1 0.0
2 2 .7
    };
    \end{axis}
    \end{pgfinterruptboundingbox}
    \draw[use as bounding box] ([xshift=1cm,yshift=0.5cm]current axis.south west) 
    rectangle ([xshift=-1cm,yshift=-0.5cm]current axis.north east);
    \end{tikzpicture}
\end{document}

这相当于 pgfplots 手册第 379 页中所写的内容。

\documentclass[margin=0.5cm]{standalone}

\usepackage{pgfplots}

\pgfplotsset{compat=1.16}

\begin{document}
    \begin{tikzpicture}
    \begin{axis}[%
    enlargelimits=false,
    axis equal,
    scale only axis,
    nodes near coords={\pgfmathprintnumber\pgfplotspointmeta},
    every node near coord/.append style={xshift=0pt,yshift=-7pt, black, font=\scriptsize},
    ytick=\empty,
    xtick=\empty
    ]

    \addplot[
    matrix plot*,
    point meta=explicit]
    table[meta=C]{
        x y C
0 0 0.0
0 1 0.0
0 2 0.3

1 0 0.0
1 1 1.0
1 2 0.0

2 0 0.0
2 1 0.0
2 2 .7
    };
    \end{axis}
    \pgfresetboundingbox
    \draw[use as bounding box] ([xshift=1cm,yshift=0.5cm]current axis.south west) 
    rectangle ([xshift=-1cm,yshift=-0.5cm]current axis.north east);
    \end{tikzpicture}
\end{document}
