Bar graph name in ggplot2

Question

I made this chart with geom_bar(), would like the title (a) followed the direction of ylab, but I’m not getting it.

I used this function parameter geom_bar()

theme(plot.title = element_text(hjust = 0, size = 13))

with this result:

would like the title to be aligned with the ylab, as follows:

How to proceed? using the hjust = 0, hoped that the title would already align with the margin of ylab, but it doesn’t, I tried negative values too and I couldn’t.

Answer 1

The values of hjust can be negative for you to do what you need.

For example:

library(ggplot2)

ggplot(iris, aes(x = Species)) +
  geom_bar() +
  ggtitle("Titulo") + 
  theme(plot.title = element_text(hjust = -0.07, size = 13))
