In cograph: Analysis and Visualization of Complex Networks

Draw Polygon Donut Node

Description

Draws a donut ring on a polygon shape where segments follow polygon edges. The fill shows a proportion (0-1) as filled segments starting from the top vertex.

Usage

draw_polygon_donut(
  x,
  y,
  size,
  fill,
  border_color,
  border_width,
  alpha = 1,
  values = NULL,
  colors = NULL,
  inner_ratio = 0.5,
  bg_color = "gray90",
  donut_shape = "square",
  show_value = TRUE,
  value_size = 8,
  value_color = "black",
  value_fontface = "bold",
  value_fontfamily = "sans",
  value_digits = 2,
  value_prefix = "",
  value_suffix = "",
  value_format = NULL,
  donut_border_width = NULL,
  ...
)

Arguments

x, y	Node center coordinates (NPC units).
size	Node radius (NPC units).
fill	Fill color for the donut ring.
border_color	Border color.
border_width	Border line width.
alpha	Transparency (0-1).
values	Single numeric value (0-1) specifying fill proportion. 0.1 = 10% filled, 0.5 = 50% filled, 1.0 = full ring.
colors	Override fill color (optional).
inner_ratio	Ratio of inner to outer radius (0-1). Default 0.5.
bg_color	Background color for unfilled portion. Default "gray90".
donut_shape	Base polygon shape: "circle", "square", "hexagon", "triangle", "diamond", "pentagon".
show_value	Logical: show value in center? Default FALSE.
value_size	Font size for center value.
value_color	Color for center value text.
value_fontface	Font face for center value.
value_fontfamily	Font family for center value.
value_digits	Decimal places for value display.
value_prefix	Text before value.
value_suffix	Text after value.
value_format	Custom format function.
donut_border_width	Border width for donut ring (NULL = use border_width).
