我未能使用以下代码使用月份的首字母在 x 轴上绘制折线图:
yrange<-range(c(Estimate, lcl,ucl))
plot(nmonth, Estimate, type = "b", pch = 20, ylim = yrange,
xlab = "Months", ylab = expression(hat(beta) * " estimates" * " & " * " confidence " * " levels "))
lines(nmonth, ucl, lty = 2)
lines(nmonth, lcl, lty = 2)
abline(h = 0, lty = 3)
还有这个。
ggplot(data=df1, aes(x=nmonth, y=Estimate)) + geom_line() + geom_point() + geom_line(size=0.1) + geom_line(aes(y = ucl)) + geom_line(aes(y = lcl))
使用数字月份(nmonth)我可以制作一个图,但标签不是我想要的。如何在 x 轴上绘制月份的所有首字母?
数据是这样的:
