geom_donut_slice {ggtricks}

Create donut slice plot using Cartesian coordinates system

Description

There are two arguments absolutely needed in aes() mappings:

• cat A discrete categories vector.

• val A numerical values vector.

Usage

geom_donut_slice(
  mapping = NULL,
  data = NULL,
  show.legend = NA,
  na.rm = FALSE,
  inherit.aes = TRUE,
  slice_angle = 180,
  init_angle = 0,
  x0 = 0,
  y0 = 0,
  r1 = 1,
  r2 = 0.65,
  color = "black",
  alpha = 1,
  linewidth = 0.5,
  slice_position = NA,
  labels_with_tick = FALSE,
  link_with_origin = FALSE,
  labels_family = "",
  labels_size = 5,
  labels_col = "black",
  labels_hjust = 0.5,
  labels_vjust = 0.5,
  labels_fontface = "plain",
  labels_lineheight = 1.2,
  tick_lwd = 1,
  ...
)

Arguments

mapping

Set of aesthetic mappings created by aes() or aes_(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.

data

to be displayed in this layer

show.legend

logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes. It can also be a named logical vector to finely select the aesthetics to display.

na.rm

If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.

inherit.aes

If FALSE, overrides the default aesthetics, rather than combining with them.

slice_angle

Pie slice angle

init_angle

Starting angle

x0

Init position x

y0

Init position y

r1

Outer circle radius

r2

Inner circle radius, should inferior to r1 value. r1 and r2 values are swapped otherwise.

color

Plot border colour

alpha

Filling colour transparency [0,1]

linewidth

Plot border size

slice_position

Pie slice position

labels_with_tick

TRUE if we want tick when labelling categories

link_with_origin

TRUE if we want to link slice borders with origin

labels_family

Labels font family

labels_size

Labels font size

labels_col

Labels colour

labels_hjust

Labels horizontal adjusting

labels_vjust

Labels vertical adjusting

labels_fontface

Labels font face

labels_lineheight

Labels line height

tick_lwd

Ticks Size

...

other arguments passed on to layer().

Value

A ggplot2 layer.

Examples

my_df <- data.frame(cat = c("Apple", "Banana", "Pineapple"), val = c(2.65, 4.5, 6.25))
my_df |>
  ggplot2::ggplot() +
  geom_donut_slice(ggplot2::aes(cat = cat, val = val)) +
  ggplot2::coord_equal()
