`facet_wrap` 与 `facet_col`：试图强制 geom_tile 在分面面板中具有相同大小的图块并为每个分面保留 x 轴标签

Question

我正在使用 ggplot2 制作日历。我希望日历看起来像这样：

library(tidyverse)
library(lubridate)
library(ggforce)

datedb <- tibble(date = seq(as.Date("2021-09-01"), 
                                as.Date("2021-12-31"), by = 1),
                    day = day(date),
                     week_no = epiweek(date),
                     Month = month(date, label = TRUE, abbr = FALSE),
                     Wday = wday(date, label = TRUE, abbr = TRUE))

ggplot(datedb, aes(Wday, week_no)) +
  geom_tile(color = "black", fill = NA) +
  geom_text(aes(label = day), size = 3) +
  scale_y_reverse() +
  scale_x_discrete(position = "top") +
  facet_wrap(~ Month, ncol = 1, scales = "free",
             strip.position = "top") +
  theme_void() +
  theme(axis.text.x = element_text(size = 9),
        strip.placement = "outside",
        strip.text = element_text(size = 13))

但是，我注意到 10 月份的图块比其他月份小 - 10 月份的天数比其他月份多一排。我想让所有的单元格都一样大。我可以使用 ggforce 中的 facet_col 参数而不是 facet_wrap 来执行此操作：ggforce::facet_col(vars(Month), scales = "free_y", space = "free") + ...但后来我松开了我的 x 轴标签（见下图），这很重要 - 我希望每个月都显示星期几。

是否有任何“简单”的解决方案可以使我的网格单元保持相同大小和我的 x 轴标签？

采用facet_col()方法；将 scales = "free_y" 更改为 scales = "free" 不能解决问题吗？

                 day = day(date),
                 week_no = epiweek(date),
                 Month = month(date, label = TRUE, abbr = FALSE),
                 Wday = wday(date, label = TRUE, abbr = TRUE))
