\title{Plots the acf for multiple chains on top of each other.}
\description{
  Plots the autocorrelation function for a \code{mcmc.list} object.
  Plots the acf for different chains on top of each other with different
  colors. 
}
\usage{
overlayedacfplot(x, ..., main = paste("Autocorrelation for ", substitute(x)))
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{x}{A \code{mcmc.list} object containing a single variable.}
  \item{\dots}{Argument to \code{plot}}
  \item{main}{Main title for plot.}

\note{Because of the way the overlay works, this will show the worst
  autocorrelation across all chains.
