calculate_plot_dimensions: Calculate plot dimensions with aspect ratio consideration

In plotthis: High-Level Plotting Built Upon 'ggplot2' and Other Plotting Packages

Calculate plot dimensions with aspect ratio consideration

Description

This function calculates plot height and width taking into account:

• Content-based scaling (number of items on axes)

• Aspect ratio constraints

• Legend position and direction

• Minimum and maximum dimension bounds

Usage

calculate_plot_dimensions(
  base_height = 4.5,
  aspect.ratio = 1,
  n_x = NULL,
  n_y = NULL,
  x_scale_factor = 0.5,
  y_scale_factor = 0.5,
  legend.position = "right",
  legend.direction = "vertical",
  legend_n = 1,
  legend_nchar = 5,
  flip = FALSE,
  min_width = 3,
  min_height = 3,
  max_width = 12,
  max_height = 12
)

Arguments

base_height	Base height for the plot (before legend adjustments). Default is 4.5.
aspect.ratio	Aspect ratio (height/width). If NULL, width is calculated independently.
n_x	Number of categories on x-axis (for width scaling)
n_y	Number of categories on y-axis (for height scaling)
x_scale_factor	Scaling factor per x-axis category. Default is 0.5.
y_scale_factor	Scaling factor per y-axis category. Default is 0.5.
legend.position	Position of legend ("none", "right", "left", "top", "bottom")
legend.direction	Direction of legend ("vertical" or "horizontal")
flip	Whether the plot is flipped (inverts aspect ratio)
min_width	Minimum width in inches. Default is 3.
min_height	Minimum height in inches. Default is 3.
max_width	Maximum width in inches. Default is 12.
max_height	Maximum height in inches. Default is 12.

Value

A list with height and width components
