You mean:
dat <- data.frame(x = rnorm(100))
dat1 <- data.frame(
x = c(0,0),
y = c(1,0),
Label = c("Point1", "Point2")
)
ggplot(dat, aes(x)) +
geom_histogram(aes(fill = ..count..)) +
geom_point(aes(x, y, colour = Label), data = dat1, size = 4) +
scale_fill_gradient("Count", low = "green", high = "red")
Unfortunately not. In the future, you will be able to do +
scale_colour_discrete(legend = F)
