Calculate plot dimensions with aspect ratio and legend consideration

Centralized helper for computing plot height and width based on content, aspect ratio, legend position, and optional bounds. Replaces per-function ad-hoc dimension logic.

Usage

calculate_plot_dimensions(
  base_height = 4.5,
  base_width = NULL,
  aspect.ratio = NULL,
  n_x = NULL,
  n_y = NULL,
  x_scale = 0.5,
  y_scale = 0.5,
  legend.position = "right",
  legend.direction = "vertical",
  legend_n = 1,
  legend_nchar = 5,
  flip = FALSE,
  min_dim = 3,
  max_dim = 12
)

Arguments

base_height

Base height (inches) before legend adjustments

base_width

Base width; if NULL derived from aspect.ratio

aspect.ratio

Panel height/width ratio; NULL = independent sizing

n_x

Number of categories on x-axis (width scaling)

n_y

Number of categories on y-axis (height scaling)

x_scale

Per-category width increment

y_scale

Per-category height increment

legend.position

Legend position string

legend.direction

Legend direction string

legend_n

Number of legend items (for horizontal legend row estimation)

legend_nchar

Max characters in legend labels

flip

Whether coordinates are flipped

min_dim

Minimum dimension (inches)

max_dim

Maximum dimension (inches)

Value

List with height and width components
