Crosstalk with barplots

General
1

i am having trouble finding an example of using barplots with cross talk. it seems unresponsive to clicks on the barplots. What am i doing wrong? @cpsievert?

library(crosstalk)
library(plotly)

shared_data <- SharedData$new(data.frame(x=1:10,y=rnorm(10),z=sample(1:4,10,replace = TRUE)),key = ~z)

p1 <- plot_ly(shared_data,x=~x,y=~y,text=~z,type='bar')%>%highlight('plotly_click',color='red')
p2 <- plot_ly(shared_data,x=~x,y=~abs(y),text=~z,type='bar')%>%highlight('plotly_click',color='red')
p3 <- plot_ly(shared_data,x=~x,y=~y,text=~z,type='scatter',mode='markers')%>%highlight('plotly_selected',color='red')


bscols(subplot(p1, subplot(p2,p3,nrows=1),nrows=2))

You can only have one highlight() definition in a single plotly graph (which is why this code chunk returns the Can only have one: highlight warning). Brushing and dragging bars (or points) actually works in this case (because plotly is taking the last highlight definition). This is closer to what you want:

bscols(p1, p2, p3)

PS. somewhat relatedly, plotly has pretty good support for targeting aggregated trace types (e.g., bar, box, violin, etc), but when the selection derives from an aggregated trace type, things can get a bit wonky (this example works because you've pre-specified bar heights). This would be a fairly big endeavor to solve completely, and isn't one of our priorities, but if you'd like to support development, please get in touch.

ok, thanks.

the layout of (1,1,2,3,nrow=2) is important to me. how do i get it to have same layout without nesting subplots?

regarding PS, i'll put it on my todo list :).

doing what you suggested made my rstudio session freeze with spinning colour wheel

bscols(p1, p2, p3, widths = c(12, 6, 6))

and the more concerning freeze problem?

Try re-running outside of RStudio in a clean session? Works for me inside RStudio...
