Using Shift on event_data("plotly_click") only stores last key

Inizia con l’app Shiny minima presente nell’issue e traccia event_data("plotly_click") insieme a highlight() e event_data("plotly_selected"). Confronta il modo in cui lo stato del clic con Shift viene rappresentato per entrambi gli eventi, quindi definisci il completamento come la restituzione di tutte le chiavi evidenziate per gli eventi di clic oppure come la documentazione e l’implementazione di un modo per disabilitare Shift per i clic mantenendo il comportamento di selezione.

When using the SHIFT-key on a plotly_click event, it returns only the last clicked key, whereas using SHIFT on plotly_selected stores all selected keys.

Is it possible to adapt the event_data("plotly_click") to be consistent with the highlighting and return all clicked/highlighted elements?

Or can I deactivate SHIFT for click-events alltogether and leave it activated for selection-events?

Shiny-App:

library(shiny)
library(ggplot2)
library(plotly)

dfN <- data.frame(
  time_stamp = seq.Date(as.Date("2018-04-01"), as.Date("2018-07-30"), 1),
  val = runif(121, 100,1000),
  col = "green", stringsAsFactors = F
)


ui <- fluidPage(
  plotlyOutput("plot"),
  verbatimTextOutput("clicked"),
  verbatimTextOutput("selection")
)

server <- function(input, output, session) {
  output$plot <- renderPlotly({
    key <- highlight_key(dfN)
    p <- ggplot() +
      geom_col(data = key, aes(x = plotly:::to_milliseconds(time_stamp), y = val, fill=I(col))) +
      theme(legend.position="none")
    
    ggplotly(p, source = "Src") %>% layout(xaxis = list(tickval = NULL, ticktext = NULL, type = "date")) %>% 
      highlight(selectize=F, off = "plotly_doubleclick", on = "plotly_click", color = "blue",
                opacityDim = 0.5, selected = attrs_selected(opacity = 1))
  })
    

  output$clicked <- renderPrint({
    s <- event_data("plotly_click", source = "Src")
    s
  })
  output$selection <- renderPrint({
    s <- event_data("plotly_selected", source = "Src")
    s
  })
}

shinyApp(ui, server)
