This is a shortcut for supplying the limits argument to the individual scales. By default, any values outside the limits specified are replaced with NA. Be warned that this will remove data outside the limits and this can produce unintended results. For changing x or y axis limits without dropping data observations, see coord_cartesian().

lims(...)

xlim(...)

ylim(...)

Arguments

...

For xlim() and ylim(): Two numeric values, specifying the left/lower limit and the right/upper limit of the scale. If the larger value is given first, the scale will be reversed. You can leave one value as NA if you want to compute the corresponding limit from the range of the data.

For lims(): A name--value pair. The name must be an aesthetic, and the value must be either a length-2 numeric, a character, a factor, or a date/time. A numeric value will create a continuous scale. If the larger value comes first, the scale will be reversed. You can leave one value as NA if you want to compute the corresponding limit from the range of the data. A character or factor value will create a discrete scale. A date-time value will create a continuous date/time scale.

Examples

# Zoom into a specified area ggplot(mtcars, aes(mpg, wt)) + geom_point() + xlim(15, 20)
#> Warning: Removed 19 rows containing missing values (geom_point).
# reverse scale ggplot(mtcars, aes(mpg, wt)) + geom_point() + xlim(20, 15)
#> Warning: Removed 19 rows containing missing values (geom_point).
# with automatic lower limit ggplot(mtcars, aes(mpg, wt)) + geom_point() + xlim(NA, 20)
#> Warning: Removed 14 rows containing missing values (geom_point).
# You can also supply limits that are larger than the data. # This is useful if you want to match scales across different plots small <- subset(mtcars, cyl == 4) big <- subset(mtcars, cyl > 4) ggplot(small, aes(mpg, wt, colour = factor(cyl))) + geom_point() + lims(colour = c("4", "6", "8"))
ggplot(big, aes(mpg, wt, colour = factor(cyl))) + geom_point() + lims(colour = c("4", "6", "8"))
