理想的结果是在图表上有24个点（从2011年到2012年的12个月），并且有一条无缝线你显然没有意识到你的“日期”实际上是字符值，将2011和2012值混合在一起，因为字符值是基于前导字符排序的，在您的示例中，前导字符是一个月中的几天。它完全混淆了对季节趋势的任何正确估计，因此首先要做的是通过构造“真实”的R日期值，然后使用
geom_smoothdf$dt <- as.Date(df$dteday, format="%d/%m/%Y")
ggplot(df, aes(x=dt, y=cnt, group = 1))+
geom_line() +
labs(title = "Bike Rentals According to Month",

y = "Count",
color = "lightblue") + geom_smooth()
df$dt啊，这就是我的日期值混乱的原因。谢谢
