#'
#' @param method Which method was used to differ variables in a plot? Two possible value: color or fill.
#' @param color Which color group we want to implement? Four possible group: categorical colors,diverging_colors, sequential colors or other color vector. Default value: categorical_colors
#' @param legend_title Title of legend. Default value: "Legend"
