Description
When using plotly with Shiny, would it be possible to implement a feature in plotly::plotlyOutput() similar to plotOutput("plot", click = "plot_click") to capture the exact coordinates of a mouse click like in the example below?
library(shiny)
ui <- basicPage(
plotOutput("plot1", click = "plot_click"),
verbatimTextOutput("info")
)
server <- function(input, output) {
output$plot1 <- renderPlot({
plot(mtcars$wt, mtcars$mpg)
})
output$info <- renderText({
paste0("x=", input$plot_click$x, "\ny=", input$plot_click$y)
})
}
shinyApp(ui, server)
I am hoping to be able to reproduce the exact mouse click positions during a data analysis and reuse them in a different analysis.

- Open a pull request that references the issue number.
Research direction
The request centers on plotly::plotlyOutput() and the Shiny plotOutput(..., click=...) behavior shown in the example. First trace how plotly outputs integrate with Shiny, then verify that mouse clicks expose exact x and y coordinates through the requested input; done means a working equivalent API demonstrated with those coordinate values.
