\title{ Default Panel Function for barchart}
\description{
Default panel function for \code{barchart}.
}
\usage{
panel.barchart(x, y, box.ratio = 1,
horizontal = TRUE,
origin = NULL, reference = TRUE,
stack = FALSE,
groups = NULL,
col = if (is.null(groups)) bar.fill$col else superpose.fill$col,
\dots)
}
\arguments{
\item{x}{ Extent of Bars. By default, bars start at left of panel,
unless \code{origin} is specified, in which case they start there
}
\item{y}{ Horizontal location of bars, possibly factor}
\item{box.ratio}{ratio of bar width to inter-bar space}
\item{horizontal}{ logical. If FALSE, the plot is `transposed' in the
sense that the behaviours of x and y are switched. x is now
the `factor'. Interpretation of other arguments change
accordingly. See documentation of \code{bwplot} for a fuller
explanation.
}
\item{origin}{ origin of the bars. For grouped displays with
\code{stack = TRUE}, this argument is ignored and the origin set to
0. Otherwise, defaults to \code{NULL}, in which case bars start at
leftmost end of panel.
}
\item{reference}{ logical, whether a reference line is to be drawn at
the origin
}
\item{stack}{ logical, relevant when groups is non-null. If
\code{FALSE} (the default), bars for different values of the
grouping variable are drawn side by side, otherwise they are
stacked.
}
\item{groups}{ optional grouping variable}
\item{col}{ Color of the bars. By default, the trellis parameter
\code{bar.fill} is used if there is no grouping variable, otherwise
\code{superpose.fill} is used.
}
\item{\dots}{ extra arguments will be accepted but ignored }
}
\details{
A barchart is drawn in the panel. Note that most arguments controlling
the display can be supplied to the high-level \code{barchart} call
directly.
