Histogram using scale_x_continuous() to start from 0

Question

I'm trying to create a histogram with tick marks at each bar. However, when I use scale_x_continuous(), the x-axis adjusted to the lowest number, which happens to be not 0. How can I make the x-axis start from 0? I tried x_lim(0,20) but it got over-ruled by scale_x_continuous().

set.seed(1234)

dat <- as_tibble(sample(20, 100, replace = TRUE)) %>% 
  filter(value > 5)

ggplot(dat, aes(value)) +
  geom_histogram(color = "white", fill = "dark grey", binwidth = 1, boundary = -0.5) +
  scale_x_continuous(breaks = seq(0, 20, 1))

Answer 1

It's xlim(0,20) not x_lim(0,20)

library(tidyverse)

set.seed(1234)

dat <- as_tibble(sample(20, 100, replace = TRUE)) %>% 
  filter(value > 5)


ggplot(dat, aes(value)) +
  geom_histogram(color = "white", fill = "dark grey", binwidth = 1, boundary = -0.5) +
  scale_x_continuous(breaks = seq(0, 20, 1)) +
  xlim(0,20)
