A theme for population pyramids — theme

theme_pyramid() is ggplot2::theme_minimal() adjusted for pyramids. It removes the grid lines that run along the bars, which the age axis already marks, keeps the major grid lines across the value axis, and puts the legend above the plot, where it reads as a heading for the two sides.

Usage

theme_pyramid(..., flipped = FALSE)

Arguments

...: Arguments passed on to ggplot2::theme_minimal(), such as base_size or base_family.
flipped: If FALSE (the default), the pyramid is horizontal, with age on the y axis. Set it to TRUE for a vertical pyramid, with age on x.

Value

A ggplot2 theme.
