plot_radial_distance: Radial Distance Visualization with Collision Avoidance

In STDistance: Spatial Transcriptomics Distance Calculation and Visualization

Radial Distance Visualization with Collision Avoidance

Description

Creates a radial plot with automatic label placement to prevent overlaps between nodes and text labels.

Usage

plot_radial_distance(
  distance_result,
  reference_type,
  id_col = "barcode",
  scale_radius = 1,
  show_labels = TRUE,
  palette = "Set2",
  label_padding = 0.15,
  center_label_expansion = 1.5
)

Arguments

distance_result	Data.frame from calculate_nearest_distances()
reference_type	Name of the reference cell type (center node)
id_col	Name of ID column (default: "barcode")
scale_radius	Scaling factor for layout (default: 1)
show_labels	Whether to show distance labels (default: TRUE)
palette	Color palette name (default: "Set2")
label_padding	Radial padding for labels (default: 0.15)
center_label_expansion	Center expansion for labels (default: 1.5)

Value

A ggplot2 object

Examples

plot_radial_distance(distance_results,id_col = "Newbarcode",
                     reference_type = "Macrophages",label_padding = 0.3,
                     show_labels = TRUE,palette = "Dark2")
