r - 尝试平衡 grid.arrange 和arrangeGrob 中图的底部。还尝试移动 Y 轴标签

Question

我有 3 个地 block ，其中两个地 block 堆叠在一起以显示为一个地 block 。我制作了一个并排(2 列)图，因此它看起来像是两个相邻的图(尽管同样，一个图实际上是两个图堆叠在一起)。我有两个问题:

1. 无论我尝试什么(垂直调整、缩放等)，我都无法使两个并排图的底部均匀。

2. 我无法获得以堆叠图为中心的 Y 轴标签，因为您无法制作跨越两个图的标签。我尝试对整个面板使用“标题”，但无法更改字体大小以匹配其余标签。

我尝试过使用 vjust、为整个绘图添加标题、使用plot_grid 以及我能想到的其他所有方法。

grid.arrange(arrangeGrob(g.top, g.bottom), gg, ncol = 2)

您可以使用patchwork package布置情节。有关布局系统如何工作的详细信息，请参阅 Vignette:

从 github 安装包:

devtools::install_github("thomasp85/patchwork")

那么，

library(patchwork)

{g.top + g.bottom + plot_layout(ncol=1)} - gg
