How to compartmentalize labels on the x axis

[Hersh]

Hello everyone,
As indicated in the title of the topic, I would like to be able to compartmentalize my labels on the x-axis in a ggplot (geom_col).

For example I have a graph with several attributes on the X axis:
1 2 3 4 5 6 7 8 9 10

For example, I would like to create compartments that will be seen on the X axis
For example having 1,2 and 6 under one compartments, etc.
Here is an example :

thank you very much

Will this do the job? I've done something slightly hacky with facets but it seems to do the job. You might want to change the theming of the facet strip.

library(tidyverse)

df = tibble(x = 1:10) %>% 
  mutate(
    area = case_when(
      x %in% c(1,2,6) ~ "Area 1",
      x %in% c(4,5,8) ~ "Area 2",
      x %in% c(3,7,9,10) ~ "Area 3"
    ),
    x = factor(x),
    y = 1:10) 

ggplot(df, aes(x, y)) +
  geom_col() +
  facet_wrap(~area, scales = "free_x", strip.position = "bottom") +
  theme_light() +
  theme(strip.placement = "outside",
        panel.border = element_blank(),
        axis.line = element_line()) +
  labs(x = "X LABEL", y = "Y LABEL")

Hi @JackDavison Thank you very much, that's exactly it!
How do I find my subcategories in my database?
I have a single database and the 1:10 categories are for example in a "Subarea" column. How would you integrate them from a dataframe that we will call df?

Thanks for your time
