R: gradient fill for geom_rect in ggplot2

Question

I want to create in R a graphic similar to the one below to show where a certain person or company ranks relative to its peers. The score will always be between 1 and 100.

Answer 1

I think that geom_tile() will be better - use sales for y and fill. With geom_tile() you will get separate tile for each sales value and will be able to see the gradient.

ggplot(mydf) +
  geom_tile(aes(x = 1, y=sales, fill = sales)) +
  scale_x_continuous(limits=c(0,2),breaks=1)+
  scale_fill_gradient2(low = 'blue', mid = 'white', high = 'red', midpoint = 50) +
  theme_minimal()
