How to choose variable to display in tooltip when using ggplotly?

Question

I have a simple data frame:

seq <- 1:10
name <- c(paste0(\"company\",1:10))
value <- c(250,125,50,40,40,30,20,20,10,10)
d <- data.frame(seq,name,         


        

Answer 1

You'll have to modify the plotly object to do this. Or use plot_ly() to create the graph instead...

EDIT: With the release of plotly 4.0 the syntax will change a little bit.

seq <- 1:10
name <- c(paste0("company",1:10))
value <- c(250,125,50,40,40,30,20,20,10,10)
d <- data.frame(seq,name,value)

require(plotly)
gg <- ggplot(data = d,aes(x=seq,y=value))+geom_line() + geom_point()

gg <- plotly_build(gg)

#OLD:
gg$data[[1]]$text <- paste("Seq:", d$seq, "
",
                           "Value:", d$value, "
",
                           "Company:", d$name)

#UPDATED: 
#Plotly_build creates two separate traces:
#One with mode = markers and the other with mode = lines
#Hence modify text for the second trace

gg$x$data[[2]]$text <- paste("Seq:", d$seq, "
",
                           "Value:", d$value, "
",
                           "Company:", d$name)
