我想使用 minipage 将所有 4 个图表放在一页（一个面板）上。另外，我是否可以将图表垂直放置而不是水平放置？谢谢。

答案1
您可以缩小每个轴的尺寸，并将其与 一起放置\caption在 中minipage，然后将所有四个 放在minipage同一个 中figure。但由于所有轴标签可能会变得有点拥挤，所以我建议另一种方法，使用groupplots。
要使条形图垂直，您需要从 切换xbar到ybar，并将所有 切换x<things>到y<things>，反之亦然。例如，xtick切换到ytick。坐标的顺序也必须改变，例如从coordinates {(0,1) (4.1,2) (16.8,3) (54.4,4)}切换到
coordinates {(1,0) (2,4.1) (3,16.8) (4,54.4)};
