#' Individual plot

#' @param ctr pmx controller
#' @param which_pages \code{integer} page(s) to display, or \code{character}
#' "all" to display all pages (argument previously called npage, now deprecated)
#' @param ... others graphics parameters passed :
#' \itemize{
#' \item \code{\link{pmx_gpar}} internal function to customize shared graphical parameters
#' \item \code{\link{individual}} generic object for individual plots.
#' \item \code{\link{pmx_update}} function.

#' \strong{individual parameters}
#' @param dname \code{character} name of dataset to be used. User can create his own
#' dataset using \code{\link{set_data}} and pass it as dname to be plotted.
#' @param pred_line \code{list} some ipred line geom properties aesthetics
#' @param ipred_line \code{list} some pred line geom properties aesthetics
#' @param point \code{list} some point geom properties aesthetics
#' @param is.legend \code{logical} if TRUE add a legend
#' @param use.finegrid \code{logical} if FALSE use predictions data set
#' @param bloq \code{pmxBLOQ} object created by \code{\link{pmx_bloq}}.


#'
#' \strong{pmx_update parameters}

#' @param filter \code{expression} filter which will be applied to plotting data.
#' @param strat.facet \code{formula} optional stratification parameter by facetting.
#' This split plot by strats(each strat in a facet)
#' @param facets \code{list} facet_wrap parameters.
#' @param strat.color \code{character} optional stratification parameter by grouping.
#' This will split the plot by group (color) of strat.
#' @param trans \code{character} define the transformation to apply on x or y or both variables
#' @param pmxgpar a object of class pmx_gpar possibly the output of the

#'
#' \strong{pmx_gpar: Shared basic graphics parameters}

#' @param labels \code{list} list containing plot and/or axis labels: title, subtitle, x , y
#' @param axis.title \code{list} containing element_text attributes to customize
#' the axis title. (similar to ggplot2 axis.title theme)
#' @param axis.text \code{list} containing element_text attributes to customize
#' the axis text (similar to ggplot2 axis.text theme)
#' @param ranges \code{list} limits of x/y ranges
#' @param is.smooth \code{logical} if set to TRUE add smooth layer
#' @param smooth \code{list} geom_smooth graphical/smoothing fun parameters
#' @param is.band \code{logical} if TRUE add horizontal band
#' @param band \code{list} horizontal band parameters. geom_hline graphical parameters.
#' @param is.draft \code{logical} if TRUE add draft layer
#' @param draft \code{list} draft layer parameters. geom_text graphical parameters.
#' @param is.identity_line \code{logical} if TRUE add an identity line
#' @param identity_line \code{list}geom_abline graphical parameters.
#' @param scale_x_log10 \code{logical} if TRUE use log10 scale for x axis.
#' @param scale_y_log10 \code{logical} if TRUE use log10 scale for y axis.
#' @param color.scales \code{list} define scales parameter in case of strat.color \code{\link{pmx_settings}}
#' @param print  \code{logical} if TRUE the ouptut will be a print not a ggplot2. This
#' is useful for rmarkdwon output to avoid verbose list index print.
