Hi @zjwinn, you can achieve the previous behavior by adding show.legend = TRUE in your call to geom_segment(). A simplified reprex:
library("ggplot2")
dat <- data.frame(
x = 1:2,
y = 1:2,
z = factor(c(1, 2), levels = c("1", "2", "3"))
)
ggplot(dat, aes(x = x, y = y, color = z)) +
geom_point(show.legend = TRUE) +
scale_color_manual(values = c("1" = "goldenrod", "2" = "coral", "3" = "sienna"), drop = FALSE)
Created on 2024-06-28 with reprex v2.1.0
from ggplot2.
