geom_area {ggplot2} | R Documentation |
An area plot is the continuous analog of a stacked bar
chart (see geom_bar
), and can be used to
show how composition of the whole varies over the range
of x. Choosing the order in which different components
is stacked is very important, as it becomes increasing
hard to see the individual pattern as you move up the
stack.

An area plot is a special case of
geom_ribbon
, where the minimum of the range
is fixed to 0, and the position adjustment defaults to
position_stacked.
