+\usage{
+hc_freq_by_year_ci(
+  df,
+  as.alternatives = FALSE,
+  ylabel = if (as.alternatives) "\%" else "ipm",

+}
+\arguments{
+\item{df}{data frame like the value of a \code{\link{frequencyQuery}}}
+
+\item{as.alternatives}{boolean decides whether queries should be treated as mutually exclusive and exhaustive wrt. to some meaningful class (e.g. spelling variants of a certain word form).}
+
+\item{ylabel}{defaults to \% if \code{as.alternatives} is \code{true} and to "ipm" otherwise.}
+
+\item{smooth}{boolean decides whether the graph is smoothed using the highcharts plot types spline and areasplinerange.}
+
+\item{...}{additional arguments passed to \code{\link{hc_add_series}}}
+
+\item{hc}{highchart}

+\description{
+Experimental convenience function for plotting typical frequency by year graphs with confidence intervals using highcharter.
+\bold{Warning:} This function may be moved to a new package.
+
+Adds on-click events to data points of highcarts that were constructed with
+\code{\link{frequencyQuery}} or \code{\link{collocationScoreQuery}}. Clicks on data points
+then launch KorAP web UI queries for the given query term and virtual corpus in
+a separate tab.
