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,

Building on @UweBlock's answer, you can also create dummy aesthetics in order to display multiple labels in tooltips. I can't find where this is documented, but discovered it emperically. The dummy variables show up in the order you specify them, but priority is given to the default variables (e.g. x and y). To get around this, you can specify those variables in a separate aesthetic, as shown below:

library(plotly)
p = ggplot(iris, aes(label=Species, label2=Petal.Length, label3=Petal.Width)) + 
  geom_point(aes(Sepal.Length,Sepal.Width))
ggplotly(p)
