如何使用 tikz 在同一图形中绘制两个图表？

Question

我想用 tikz 绘制两个图表（一个在左边，另一个在右边）。这是我的代码，但它只能在一个图中绘制一个图表。非常感谢

\begin{figure}[htb] 
    \centering
    \begin{tikzpicture}


    \begin{axis}[
        ybar,
        xlabel = X,
        xmin = -0.3,xmax = 4.3,
        ymin = 0, ymax = 10,
        axis x line* = bottom,
        axis y line* = left,
        ylabel= Y,
        width= 0.9\textwidth,
        height = 0.6\textwidth,
        ymajorgrids = true,
        bar width = 0.5mm,
        xticklabels = \empty,
        extra x ticks = {0,1,2,3,4},
        extra x tick labels = {0,1,2,3,4},
        legend pos=north east,
        ]

        \addplot coordinates {
            (0,2)
            (1,6)
            (2,6)
            (3,6)
            (4,6)
        };
        \addplot coordinates {
            (0,5)
            (1,5)
            (2,5)
            (3,5)
            (4,5)
        };
        \addlegendimage{empty legend}
        \addlegendentry{$A$}
        \addlegendentry{$B$}
    \end{axis} 
    \end{tikzpicture}
    \caption{chart}
\end{figure}

这显示了如何向一个图形添加两个（子标题包）子图。有许多不同的包带有子图，但它们都是美化的迷你页面。

这是一份包含群体地块的提案。
