Based on this question Force the origin to start at 0 I want to implement this into a new created theme and not just as a default setting.
data(iris)
ggplot(iris, aes(x = Species)) +
geom_bar() +
scale_y_continuous(expand = expansion(mult = c(0, 0.05)))
How can I do this without defining it every single plot?
As far as I know this not possible via theme(). But you can define a wrapper around scale_y_continuous like so
library(ggplot2)
data(iris)
scale_y_origin <- function(...) {
scale_y_continuous(expand = expansion(mult = c(0, 0.05)), ...)
}
ggplot(iris, aes(x = Species)) +
geom_bar() +
scale_y_origin()
