如何在一个图中绘制两个直方图(不同的行长) (ggplot)

library(ggplot2)

# 准备数据
data1 <- c(1, 2, 3, 4, 5)
data2 <- c(2, 4, 6, 8, 10)

# 创建数据框
df <- data.frame(
  value = c(data1, data2),
  group = c(rep("Group 1", length(data1)), rep("Group 2", length(data2)))
)

# 绘制直方图
ggplot(df, aes(x = value, fill = group)) +
  geom_histogram(binwidth = 1, position = "dodge") +
  labs(x = "Value", y = "Count", title = "Comparison of Two Histograms")
