#' Dynamic Figure Length Generator
#'
#' This function calculates the appropriate figure height depending on the
#' number of items.
#'
#' @param default_size The default figure length. Must be numeric.
#' @param number_of_items Number of peak files, or terms.
#' @param max_items Maximum number of peak files, or terms.
#'
#' @return Figure height/width. A number.
#' @keywords internal
