scale_color_manual colors won't change

Question

I am trying to change the colors in a plot manually but

My code with dummydata:

df2=data.frame(y=runif(10), ontopic=c(F,F,F,F,F,T,T,T,T,T))

plot_right &         


        

Answer 1

Using scale_fill_manual instead of scale_colour_manual should work.

ggplot(df2, aes(y, fill = ontopic, colour= ontopic)) + 
  geom_density(alpha = 0.5) + 
  coord_flip()  + theme(legend.position = "none")+
  scale_y_continuous(breaks=seq(0, 1, 0.5)) +
  scale_fill_manual(values=c("#999999", "#E69F00"))
