# plotOptions.series.events.legendItemClick

Fires when the legend item belonging to the series is clicked. One parameter, `event`, is passed to the function. The default action is to toggle the visibility of the series. This can be prevented by returning `false` or calling `event.preventDefault()`.

Note: This option is deprecated in favor of legend.events.itemClick.
