Changing the default

 wine %>%
  count(Type) %>%  
  plot_ly(x = ~Type, y = ~n,
      # Changing the default info displayed
          hoverinfo = "y" 
  ) %>%
  add_bars()

hoverinfo =

"all"
"x"
"y"
"x+y"
"x+y+z"

Custom hover text

wine %>%
  plot_ly(x = ~Flavanoids, y = ~Alcohol,

    hoverinfo = "text",

    text = ~paste("Flavanoids:", Flavanoids, "<br>",
                  "Alcohol:", Alcohol)

          ) %>%
  add_markers()

tilde, ~, to map columns to aesthetic parameters
