geom_scatterpie

Description

scatter pie plot

Usage

geom_scatterpie(
  mapping = NULL,
  data,
  cols,
  pie_scale = 1,
  sorted_by_radius = FALSE,
  legend_name = "type",
  long_format = FALSE,
  donut_radius = NULL,
  bg_circle_radius = NULL,
  ...
)

Arguments

mapping

aes mapping

data

data

cols

cols the pie data

pie_scale

amount to scale the pie size if there is no radius mapping exists

sorted_by_radius

whether plotting large pie first

legend_name

name of fill legend

long_format

logical whether use long format of input data

donut_radius

numeric the radius of donut chart (relative the radius of circle), default is NULL. it should be between 0 and 1, if it is provided, the donut chart will be displayed instead of pie chart.

bg_circle_radius

numeric the radius of background circle, default is FALSE, we suggest setting it to between 1 and 1.5 .

...

additional parameters

Value
