使用ggplot在同一图上的三组不同的点

install.packages("ggplot2")

library(ggplot2)

data <- data.frame(
  x = c(group1_x, group2_x, group3_x),
  y = c(group1_y, group2_y, group3_y),
  group = rep(c("Group 1", "Group 2", "Group 3"), each = length(group1_x))
)

plot <- ggplot(data, aes(x = x, y = y))

plot + geom_point(aes(color = group))

plot + geom_point(aes(color = group), shape = "o", size = 3, alpha = 0.5)

plot + geom_point(aes(color = group), shape = "o", size = 3, alpha = 0.5) +
  labs(color = "Group", x = "X", y = "Y", title = "Three Groups of Points") +
  theme_minimal()
