顯示彼此相鄰且 x 軸對齊的兩個圖表

如何對齊以下兩個圖表以使它們的 x 軸對齊？在這兩個圖中，y 軸的頂部都比我想要的要高。它的高度似乎在 13 到 14 之間。

\documentclass{amsart}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11}

\begin{document}

\begin{tikzpicture}
\begin{axis}[width=3in,axis equal image,
    axis lines=middle,
    xmin=-4,xmax=8,samples=101,
    xlabel=$x$,ylabel=$y$,
    ymin=-2,ymax=10,
    restrict y to domain=-2:10,
    enlargelimits={abs=1cm},
    axis line style={latex-latex},
    ticklabel style={font=\tiny,fill=white},
    xtick={2,10},ytick={},
    xlabel style={at={(ticklabel* cs:1)},anchor=north west},
    ylabel style={at={(ticklabel* cs:1)},anchor=south west}
]
\addplot [latex-latex,domain=-4:8] {x + 2} node [pos=0.9, anchor=north west, font=\footnotesize] {$y=f(x)$};
\draw [fill=white] (2,4) circle [radius=1.5pt] node[right,font=\tiny]{$(2, \, 4)$};
\end{axis}
\end{tikzpicture}

若要使最大 y 值相同，請消除並指定兩個圖表所需enlargelimits的值：ymax=11

在此輸入影像描述

筆記：

  • 要使兩個圖表彼此相鄰，您需要消除\end{tikzpicture}和之間的空白行\begin{tikzpicture}。
  • 這還需要添加一個left選項來放置圖形標籤。

代碼：

    restrict y to domain=-2:10,
    %enlargelimits={abs=1cm},

    xtick={2,10},ytick={},
    xlabel style={at={(ticklabel* cs:1)},anchor=north west},
    ylabel style={at={(ticklabel* cs:1)},anchor=south west}
]
\addplot [latex-latex,domain=-4:8] {x + 2} node [pos=0.9, anchor=north west, font=\footnotesize, left] {$y=f(x)$};
\draw [fill=white] (2,4) circle [radius=1.5pt] node[right,font=\tiny]{$(2, \, 4)$};
\end{axis}
\end{tikzpicture}
