SharedData

shared_launches <- SharedData$new(launches, key = ~agency_type)

line_chart <- shared_launches %>%
  plot_ly() %>%
  group_by(launch_year, agency_type) %>%
  summarize(n = n()) %>%
  ungroup(launch_year) %>%
  add_lines(x = ~launch_year, y = ~n, color = ~agency_type) 
bar_chart <- shared_launches %>%
  plot_ly() %>%
  group_by(agency_type) %>%
  summarize(n = n()) %>%
  add_bars(y = ~fct_reorder(agency_type, n), x = ~n, color = ~agency_type) %>%
  layout(barmode = "overlay", yaxis = list(title = ""))

Views koppelen met subplot()

subplot(bar_chart, line_chart) %>% 
  hide_legend() %>% 
  highlight()

Views koppelen met bscols()

bscols(
  widths = c(4, NA),
  bar_chart %>% highlight(),
  line_chart %>% highlight()
)

highlight()-opties

Argument	Beschrijving
`on`	selectie-event: `'plotly_click'`, `'plotly_hover'` of `'plotly_selected'`
`off`	event om selectie uit te zetten: `'plotly_doubleclick'`, `'plotly_deselect'` of `'plotly_relayout'`
`persistent`	Selecties vasthouden? `TRUE` of `FALSE`
`dynamic`	Widget toevoegen om kleuren te wijzigen? `TRUE` of `FALSE`
`color`	string met kleur(en) voor highlighten van selecties
`selectize`	selectize.js-widget toevoegen voor het selecteren van keys? `TRUE` of `FALSE`

Selector-widgets

bscols(widths = c(2, NA),
  list(filter_checkbox(id = "agency", label = "Type agentschap", shared_launches, ~agency_type),
       filter_select(id = "agency2", label = "Dropdown agentschapstype", shared_launches, ~agency_type)),
  line_chart %>% highlight(on = "plotly_selected", off = "plotly_deselect")
)
