library(ggplot2)
a <- ggplot(mtcars, aes(x = mpg)) + geom_histogram(binwidth = 4) + 
  theme(plot.margin=unit(c(1, 1, 1, 1),'cm'))

b <- ggplot(mtcars, aes(x = mpg)) + geom_histogram(binwidth = 4) + 
  theme(plot.margin=unit(c(2, 2, 2, 2),'cm'))

c <- ggplot(mtcars, aes(x = mpg)) + geom_histogram(binwidth = 4) + 
  theme(plot.margin=unit(c(3, 3, 3, 3),'cm'))

d <- ggplot(mtcars, aes(x = mpg)) + geom_histogram(binwidth = 4) +
