scale_x_break — scale_x_break • ggbreak

Set an axis break point for a 'gg' plot

scale_x_break(
  breaks,
  scales = "fixed",
  ticklabels = NULL,
  expand = TRUE,
  space = 0.1
)

scale_y_break(
  breaks,
  scales = "fixed",
  ticklabels = NULL,
  expand = TRUE,
  space = 0.1
)

Arguments

breaks: break point
scales: relative width or height of subplots, default is "fixed". If scale is 'free', all subplots have equal width or height. It also can be any number to set relative width or height compare to first subplot.
ticklabels: the axis labels to subplot, default is NULL.
expand: default is TRUE, logical or a vector of range expansion constants used to add some padding around the data to ensure that they are placed some distance away from the axes. Use the convenience function expansion() of ggplot2 to generate the values for the expand argument. The defaults are to expand the scale by 5% on each side for continuous variables. If it is logical, the TRUE means the default of ggplot2 (foregoing statement), and FALSE means no expand for the plot.
space: the blank space among the subplots after break, default is 0.1 (cm).

Value

gg object

Details

This scale function set an axis break point for a 'gg' plot. Either 'x' and 'y' axes are supported. The result is still a 'gg' object and user can progressively add layers to it.

Examples

require(ggplot2 )
set.seed(2019-01-19)
d <- data.frame(
  x = 1:20,
  y = c(rnorm(5) + 4, rnorm(5) + 20, rnorm(5) + 5, rnorm(5) + 22)
)

p <- ggplot(d, aes(x, y)) + geom_col()
x <- p+scale_y_break(c(7, 17 ) )
print(x)
