ggvis in R: Change color when mouse hover

Question

Is there a code that can realize the first example picture on the GGVIS homepage?

The function I want is that the color changes when I hover over the bar.

Thanks.

Answer 1

Try the fill.hover argument:

library(ggvis)

faithful %>% 
ggvis(~eruptions, fill := "#fff8dc", fill.hover := "#fcb5a2") %>%
  layer_histograms(width = 0.25)
