ggplot2: Legend title
I'm designing a set of plots intended for a general audience; here's the code for one of them, using the latest version of ggplot:
plot.enr.all <-
ggplot(data=df1, aes(x=HS_GRAD_YEAR, y=Percentage, group=Enrolled_by,
color=Enrolled_by, shape=Enrolled_by, fill=Enrolled_by)) +
geom_line() + geom_point(size=3.5) +
scale_y_continuous(breaks=seq(0, 100, 10),
