\name{kronoviz}
\alias{kronoviz}
\title{Plot Multiple Chronograms on the Same Scale}
\description{
The main argument is a list of (rooted) trees which are plotted on the
same scale.
}
\usage{
kronoviz(x, layout = length(x), horiz = TRUE, ...,
direction = ifelse(horiz, "rightwards", "upwards"), side = 2)
}
\arguments{
\item{x}{a list of (rooted) trees of class \code{"phylo"}.}
\item{layout}{an integer giving the number of trees plotted
simultaneously; by default all.}
\item{horiz}{a logical specifying whether the trees should be plotted
rightwards (the default) or upwards.}
\item{\dots}{further arguments passed to \code{plot.phylo}.}
\item{direction}{a character string specifying the direction of the
tree. Four values are possible: "rightwards" (the default),
"leftwards", "upwards", and "downwards".}
\item{side}{Where to put the axis, see example.}
}
\details{
The size of the individual plots is proportional to the size of the
trees.
