将 ts.plot 的 y 轴更改为对数

Question

考虑以下代码：

library(ggplot2)

t1 <- c(1, 2, 3)
t2 <- c(4, 5, 4)
t3 <- c(7, 7, 5)
data <- data.frame(t1, t2, t3)

ts.plot(t(data), gpars = list(col = ggplot2::alpha("black", 0.5), ylim = c(0, 10),
xlim = c(0, 10), xlab = "Years", ylab = "Cumulative Numbers"))

如何将 y 轴更改为对数刻度？

Answer 1

这样做有用吗？

ts.plot(t(data), gpars = list(col = ggplot2::alpha("black", 0.5), ylim = c(0.5, 10),
                              xlim = c(1, 10), xlab = "Years", ylab = "Cumulative Numbers"),log = 'y')

输出：

将 ts.plot 的 y 轴更改为对数

Change y-axis of ts.plot to logarithmic

plot

r

time-series
