#' Axis scales format
#'
#' The \code{_comma} ones set comma format for axis text, the \code{_percent}
#' ones set percent format for axis text, \code{_dollar} for collar currency,
#' and \code{_abbr} for abbreviated format. Lastly, use \code{_formatNum} to
#' further customize your numerical scales with \code{formatNum}.
#'
#' @param ... Arguments passed to \code{ggplot2::continuous_scale} or
#' \code{formatNum} depending on the function.
#' @return Reformatted scales on ggplot2 object
