ggplot multiple legends into one box
Solution 1:
I think you're looking for legend.box.background instead of legend.background:
ggplot(iris) +
theme_classic() +
geom_point(aes(x = Petal.Length, y = Sepal.Length,
color = Species, size = Sepal.Width)) +
theme(legend.position = c(0.1, 0.75),
legend.box.background = element_rect(fill = "white", color = "black"),
legend.spacing.y = unit(0,"cm"))
