Continuous baseline for faceted plots

tidyverse

Thank you @nwerth. I want to maintain some separation between the groups - my actual data is considerably more dense than the example. Adding scale_x_discrete(expand=expand_scale(add=1)) does the trick!

library(ggplot2)

ggplot(mpg, aes(class, fill=class)) + 
  geom_hline(yintercept=0) +
  geom_bar() + 
  facet_grid(cyl~trans, switch='x') +
  theme_minimal() +
  theme(axis.ticks=element_blank(),
  axis.text.x=element_blank(),
  panel.spacing.x = unit(0, "null"),
  panel.grid=element_blank()) +
  labs(x='') +
  scale_x_discrete(expand=expand_scale(add=1))
