\alias{dyLegend}
\title{dygraph legend}
\usage{
dyLegend(dygraph, show = c("auto", "always", "onmouseover", "follow",
"never"), width = 250, showZeroValues = TRUE, labelsDiv = NULL,
labelsSeparateLines = FALSE, hideOnMouseOut = TRUE)
}
\arguments{
\item{dygraph}{Dygraph to configure legend options for.}
\item{show}{When to display the legend. Specify "always" to always show the
legend. Specify "onmouseover" to only display it when a user mouses over
the chart. Specify "follow" to have the legend show as overlay to the chart
which follows the mouse. The default behavior is "auto", which results in
"always" when more than one series is plotted and "onmouseover" when only a
single series is plotted.}
\item{width}{Width (in pixels) of the div which shows the legend.}
\item{showZeroValues}{Show zero value labels in the legend.}
\item{labelsDiv}{Show data labels in an external div, rather than on the
graph. This value should be a div element id.}
\item{labelsSeparateLines}{Put a <br/> between lines in the label string.
Often used in conjunction with \code{labelsDiv}.}
\item{hideOnMouseOut}{Whether to hide the legend when the mouse leaves the
chart area. This option applies when \code{show} is set to "onmouseover".
Note that this also affects the hiding of the \code{\link{dyHighlight}} on
mouse out.}
}
\value{
A dygraph with customized legend options
}
\description{
