Cartesian coordinates with x and y flipped

Flip cartesian coordinates so that horizontal becomes vertical, and vertical, horizontal. This is primarily useful for converting geoms and statistics which display y conditional on x, to x conditional on y.

coord_flip(xlim = NULL, ylim = NULL, expand = TRUE)

Arguments

xlim	Limits for the x and y axes.
ylim	Limits for the x and y axes.
expand	If TRUE, the default, adds a small expansion factor to the limits to ensure that data and axes don't overlap. If FALSE, limits are taken exactly from the data or xlim/ylim.

Examples

# Very useful for creating boxplots, and other interval
# geoms in the horizontal instead of vertical position.

ggplot(diamonds, aes(cut, price)) +
  geom_boxplot() +
  coord_flip()

h <- ggplot(diamonds, aes(carat)) +
  geom_histogram()
h
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
h + coord_flip()
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
h + coord_flip() + scale_x_reverse()
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

# You can also use it to flip line and area plots:
df <- data.frame(x = 1:5, y = (1:5) ^ 2)
ggplot(df, aes(x, y)) +
  geom_area()
last_plot() + coord_flip()
