\item{dygraph}{Dygraph to configure highlighting behavior for.}
\item{highlightCircleSize}{The size in pixels of the dot drawn over
highlighted points.}
\item{highlightSeriesBackgroundAlpha}{Fade the background while highlighting

\item{highlightSeriesOpts}{When set, the options from this list are applied

\code{\link{dySeries}} for additional details on options that can be set.}
\item{hideOnMouseOut}{Whether to hide the highlighting effects when the mouse

\code{\link{dyLegend}} on mouse out.}
}
\value{

\description{
Configure options for data series mouse-over highlighting. Note that
highlighting is always enabled for dygraphs so this function is used to
customize rather than enable highlighting.

See the
\href{https://rstudio.github.io/dygraphs/gallery-series-highlighting.html}{online
documentation} for additional details and examples.
