Consider the example plot below. I\'d like to make the little boxes around each of the symbols in the legend go away. How an I do this?
ggplot(mtcars, aes
You're looking for:
+ opts(legend.key = theme_blank())
You can see lots of examples of all sorts of this stuff in ?opts
. I couldn't remember off the top of my head which one it was, so I just tried a few until I got it right.
Note: Since version 0.9.2 opts
has been replaced by theme
:
+ theme(legend.key = element_blank())
