Hi, I am trying to do add a legend to an overplot, something like this:
ggplot() + geom_density(data = df1, aes(x = x), fill = "green", show_guide = FALSE) + geom_area(data = df2, aes(x = x), fill = "yellow", show_guide = FALSE) + scale_color_manual(values = c("green", "yellow"), labels = c('df1', 'df2')) But the legend doesn't actually show up when I plot it. How should I fix this?
