\usage{
\method{plot}{CalGR}(x, xlab = NULL, ylab = NULL, main = NULL, which = c("perf", "iter", "ts"), ...)
}


\arguments{
  \item{x}{[object of class \emph{CalGR}] see \code{\link{CalGR}} for details}
  
  \item{xlab}{(optional) [character] a label for the x axis: see \code{\link{title}}}
  
  \item{ylab}{(optional) [character] a label for the y axis (flow and precipitation) (see \code{\link{title}})}
  
  \item{main}{(optional) [character] a main title for the plot (see \code{\link{title}})}
  
  \item{which}{[character] choice of the plot type (\code{"perf"} (default): plot diagnostics; \code{"iter"}: parameter values and the calibration criterion during the progression steps of calibration; \code{"ts"}: time series of observed precipitation and observed and simulated flows)}
  
  \item{...}{other parameters to be passed through to plotting functions}
}
