These functions extract just the axes from a ggplot. get_y_axis() pulls the y-axis, while get_x_axis() pulls the x-axis.

get_y_axis(plot, position = c("left", "right"))

get_x_axis(plot, position = c("bottom", "top"))

Arguments

plot

A ggplot or gtable.

position

Which side of the plot is the axis on? For the x-axis, this can be "top" or "bottom", and for the y-axis, it can be "left" or "right".

Examples

library(ggplot2) p <- ggplot(mpg, aes(displ, cty)) + geom_point() ggdraw(get_y_axis(p))
p <- p + scale_x_continuous(position = "top") ggdraw(get_x_axis(p, position = "top"))
