get_plot_extremes: Calculate plot extremes

In ggchord: Multi-Sequence 'BLAST' Alignment Chord Diagram Visualization Tool

Calculate plot extremes

Description

Extracts x/y coordinate extremes from all plot elements (sequence arcs, ribbons, gene arrows, etc.) for adjusting the plot range

Usage

get_plot_extremes(
  allRibbon = NULL,
  seqArcs = NULL,
  axisLines = NULL,
  axisTicks = NULL,
  gene_arrows = NULL,
  gene_polys = NULL,
  show_axis = FALSE
)

Arguments

allRibbon	data.frame, ribbon data (with x, y columns), default NULL
seqArcs	List, sequence arc data (each element is a data frame with x, y, seq_id), default NULL
axisLines	data.frame, axis line data (with x, y, seq_id columns), default NULL
axisTicks	data.frame, tick mark data (with x0, y0, x1, y1, label_x, label_y columns), default NULL
gene_arrows	data.frame, gene label data (with text_x, text_y columns), default NULL
gene_polys	data.frame, gene arrow polygon data (with x, y columns), default NULL
show_axis	Logical, whether to include extreme value calculation for axis-related elements, default FALSE

Value

List containing x_min (minimum x), x_max (maximum x), y_min (minimum y), y_max (maximum y)
