Helpers to use highcharter as input in shiny apps — hc_add_event

When you use highcharter in a shiny app, for example renderHighcharter('my_chart'), you can access to the actions of the user using and then use the hc_add_event_point via the my_chart input (input$my_chart). That's a way you can use a chart as an input.

Usage

hc_add_event_point(hc, series = "series", event = "click")

hc_add_event_series(hc, series = "series", event = "click")

Arguments

hc: A highchart htmlwidget object.
series: The name of type of series to apply the event.
event: The name of event: click, mouseOut, mouseOver. See https://api.highcharts.com/highcharts/plotOptions.areasplinerange.point.events.select for more details.

Note

Event details are accessible from hc_name_EventType, i.e. if a highchart is rendered against output$my_hc and and we wanted the coordinates of the user-clicked point we would use input$my_hc_click
