This is a shortcut for supplying the limits argument to the
individual scales. Note that, by default, any values outside the limits
will be replaced with NA.

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
A character or factor value will create a discrete scale. A date-time value will create a continuous date/time scale. |
For changing x or y axis limits without dropping data
observations, see coord_cartesian(). To expand the range of
a plot to always include certain values, see expand_limits().

# You can also supply limits that are larger than the data.
# This is useful if you want to match scales across different plots
