pgfplots：将 xlabel 拆分为两行

Question

我想将 xlabel 拆分成行。我的 MWE 如下：

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.7}

\begin{document}

\begin{tikzpicture}
    \begin{axis}[
       % xlabel = Temp, $N$ \newline Slice at X
        xlabel = Temp $N$ \newline Slice at X        
        , ylabel = $P$
        , zlabel = Response
        , xmin = -1
        , xmax = 1
        , ymin = -1
        , ymax = 1
        %, x dir = reverse
        , view={-40}{30}]
   \addplot3
   [
    surf
   ,  faceted color=blue
   , samples  = 15
   , domain   = -1:1
   , y domain = -1:1
   ]
    {56+ 1* x + 2* y + 3*x*y};
    \end{axis}
\end{tikzpicture}

\end{document}

我想知道如何将 xlabel 拆分为两行以及如何在 xlabel 中放置逗号 (,)。谢谢

xlabel打印为节点。因此，您可以设置特定的文本宽度。这允许换行。可以通过选项进行修改xlabel style。第 173 页的文档中显示了一个示例：

xlabel style={align=right,text width=3cm}

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.7}

\begin{document}

\begin{tikzpicture}
    \begin{axis}[
       % xlabel = Temp, $N$ \newline Slice at X
        xlabel style={draw,rectangle,align=left,text width=2cm},
        xlabel = Temp $N$ \newline Slice at X        
        , ylabel = $P$
        , zlabel = Response
        , xmin = -1
        , xmax = 1
        , ymin = -1
        , ymax = 1
        %, x dir = reverse
        , view={-40}{30}]
   \addplot3
   [
    surf
   ,  faceted color=blue
   , samples  = 15
   , domain   = -1:1
   , y domain = -1:1
   ]
    {56+ 1* x + 2* y + 3*x*y};
    \end{axis}
\end{tikzpicture}

\end{document}
