The on-series-click setting provides an option of linking widgets displayed on the same portal for interactive behavior such as drill-down.

on-series-click specifies an action that will be performed when the user clicks on a series. In the case of a calendar widget it’s a row of summarization periods.

Multiple on-series-click actions can be triggered to update multiple widgets simultaneously.

on-series-click = var seriesConfig = $.extend({}, c.config.originalConfig.series[0], {entity: series.entity, tags: series.tags});
on-series-click = c.replaceSeries([seriesConfig], interval)

Note: the on-series-click setting does not affect the behavior of the widget on the header click handler.
