ggplot_donut: Create a ggplot Donut (Doughnut) Plot

In jabenninghoff/jbplot: A Personal Collection of ggplot2 Themes

Create a ggplot Donut (Doughnut) Plot

Description

Create a donut plot from a data frame containing groups and corresponding values with ggplot2::ggplot().

Usage

ggplot_donut(data, group = "group", value = "n", hsize = 2)

Arguments

data	Default dataset to use for plot. If not already a data.frame, will be converted to one by fortify(). If not specified, must be supplied in each layer added to the plot.
group	Name of column to use for the plot colors.
value	Name of column to use for the sector size.
hsize	Size of the donut hole. Defaults to 2, and must be a non-negative value. A value of 0 creates a pie chart.

Details

Implemented using ggplot2::geom_col(), ggplot2::coord_polar(), and ggplot2::xlim(), adapted from guides in The R Graph Gallery and R CHARTS.

Some default plot elements are disabled using ggplot2::theme() and ggplot2::element_blank().

Examples

library(dplyr, warn.conflicts = FALSE)
library(ggplot2)
