I have the following plot like below.
It was created with this command:
library(ggplot2) df <- data.frame(cond = factor(rep(c("A", "B"), each = 200)), rating = c(rnorm(200), rnorm(200, mean=.8))) ggplot(df, aes(x=rating, fill=cond)) + geom_density(alpha = .3) + xlab("NEW RATING TITLE") + ylab("NEW DENSITY TITLE")
Now next thing I want to do is to modify the legend title from cond into NEW LEGEND TITLE.
So what I did is to just add the following line add the end of the above code:
+labs(colour="NEW LEGEND TITLE")
But it doesn’t work. What’s the right way to do it?
This should work:
p <- ggplot(df, aes(x=rating, fill=cond)) + geom_density(alpha=.3) + xlab("NEW RATING TITLE") + ylab("NEW DENSITY TITLE") p <- p + guides(fill=guide_legend(title="New Legend Title"))
p + scale_fill_discrete(name = "New Legend Title")
