Suppose I have a ggplot with more than one legend.
mov <- subset(movies, length != "")
(p0 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
geom_point()
)
I can turn off the display of all the legends like this:
(p1 <- p0 + theme(legend.position = "none"))
Passing show_guide = FALSE to geom_point turns off the shape legend.
(p2 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
geom_point(show_guide = FALSE)
)
But what if I want to turn off the color legend instead? There doesn't seem to be a way of telling show_guide which legend to apply its behavior to. And there is no show_guide argument for scales or aesthetics.
(p3 <- ggplot(mov, aes(year, rating, colour = length, shape = mpaa)) +
scale_colour_discrete(show_guide = FALSE) +
geom_point()
)
# Error in discrete_scale
(p4 <- ggplot(mov, aes(year, rating, shape = mpaa)) +
aes(colour = length, show_guide = FALSE) +
geom_point()
)
#draws both legends
I want to be able to do something like
p0 + guides(
colour = guide_legend(show = FALSE)
)
but guide_legend doesn't have a show argument.
How do I specify which legends get displayed?
