Documented in small_margin

#' @title Margin
#' @description If each variable is smaller, then the margin of it is smaller, so plot region become larger.
#' But title and x axis title will be vanished.
#'
#'@details  To show FROC curve or signal and noise distributions in Shiny Graphical devices,
#'the author write down this function \code{small_margin}. By taking margin too small, we gives more larger plot regions
