I would like to put my plot legend inside the plot, inside the first plot of a facet.
Here is some example code:
df=data.frame(
x=runif(10),
y=runif(10),
facet=rep(c("a","b"),5),
color=rep(c("red","blue"),5))
ggplot(data=df,aes(x=x,y=y,color=color))+
geom_point()+
facet_wrap(~facet,ncol=1)
Here is the resulting plot:
And here is roughly how I would like it to look:
Thanks for any help you can provide!
Assuming your plot is saved as p
p + opts(
legend.position = c(0.9, 0.6), # c(0,0) bottom left, c(1,1) top-right.
legend.background = theme_rect(fill = "white", colour = NA)
)
If you want the legend background partially transparent, change the fill
to, e.g., "#ffffffaa"
.
