event_data doesn't work with scatterplot (type = "scattergl") #624
Description
Hello,
I was trying to follow the examples from these two links:
Shiny-coupled-events
#596
Everything works fine until I changed the type = 'scatter' to type = 'scattergl'
I lost the "box select" option after the change.
In comparison, it work fine for ggplot + ggplotly and I can still get the data info from the selected box area.
I would like to use the additional features from plot_ly instead of switching back to ggplot
Thank you for your help.
Here is a minimal example code
library(shiny)
library(plotly)
adds <- mtcars[1:5, ]
adds[, c(1, 6)] <- NA
rownames(adds) <- paste(rownames(adds), "(NA)")
some_null_cars <- rbind(mtcars, adds)
ui <- fluidPage(
radioButtons("plotType", "Plot Type:", choices = c("ggplotly", "plotly")),
plotlyOutput("plot"),
verbatimTextOutput("brush")
)
server <- function(input, output, session) {
output$plot <- renderPlotly({
# use the key aesthetic/argument to help uniquely identify selected observations
key <- row.names(some_null_cars)
if (identical(input$plotType, "ggplotly")) {
p <- ggplot(some_null_cars, aes(x = mpg, y = wt, colour = factor(vs), key = key)) +
geom_point()
ggplotly(p) %>% layout(dragmode = "select")
} else {
plot_ly(some_null_cars, x = mpg, y = wt, key = key, mode = "markers", type = "scattergl") %>%
layout(dragmode = "select")
}
})
output$brush <- renderPrint({
d <- event_data("plotly_selected")
if (is.null(d)) "Click and drag events (i.e., select/lasso) appear here (double-click to clear)" else d
})
}
shinyApp(ui, server)

Marking this as a duplicate since this is a known limitation of gl2d trace types -- plotly/plotly.js#130

Sorry I missed it. Thanks

I know this is supposed to have been fixed in plotly.js but I find that the 2d scatter plot using either type='scattergl' or toWebGL() breaks the plotly_click event in plotly.r. It works fine for me for scatter3d. I want to show a 2d plot of 21,000 points, hence the need for scattergl.
This issue was reported here: plotly/plotly.js#743
but is supposed to have been completed here: plotly/plotly.js#994
Here is demo code:
