How to set up hover information in a ggplotly object?

Question

Is there a way to configure hoverinfo in a ggplotly object?

For instance,

p <- ggplot(mtcars, aes(x = disp, y= am, color = as.factor(cyl)))+geom_point()

ggplotly(p)

The guidance field contains three variables: disp, am, and factor (cyl). How to include more variables or exclude existing variables in the hover info field?

Thank!

You can include the required variables in aes(), then use tooltipto indicate what should be displayed:

p <- ggplot(mtcars, aes(x = disp, y= am, color = as.factor(cyl), 
                        gear=gear, hp=hp))+geom_point()
ggplotly(p,tooltip = c("x", "gear", "hp"))
