使用ggplot2将多个数据框合并到一个图中

install.packages("ggplot2")

library(ggplot2)

df1 <- data.frame(x = c(1, 2, 3), y = c(4, 5, 6))
df2 <- data.frame(x = c(1, 2, 3), y = c(7, 8, 9))

p <- ggplot() +
  geom_point(data = df1, aes(x = x, y = y), color = "blue") +
  geom_point(data = df2, aes(x = x, y = y), color = "red")

library(ggplot2)

df1 <- data.frame(x = c(1, 2, 3), y = c(4, 5, 6))
df2 <- data.frame(x = c(1, 2, 3), y = c(7, 8, 9))

p <- ggplot() +
  geom_point(data = df1, aes(x = x, y = y), color = "blue") +
  geom_point(data = df2, aes(x = x, y = y), color = "red") +
  labs(title = "Multiple Data Frames", x = "X", y = "Y")

print(p)
