绘制两个不同长度相同比例的系列

想要将一个图表中的两个系列绘制在x的15个数据实例（两个系列同时结束）之后的y（较短的系列）中，而不会错过图表中x的前15个数据实例。 / p>

谢谢

Answer 1

您可以尝试类似的行：

plot(var1T ~ var1S, type="l",col="red", xlim=range(c(var1S,var2S)), ylim=range(c(var1T,var2T)))
par(new=T)
plot(var2T ~ var2S, type="l",col="green", xlim=range(c(var1S,var2S)), ylim=range(c(var1T,var2T)))

Answer 2

从每个系列创建时间序列，然后绘制它们：

x.ts <- ts(x)
y.ts <- ts(y, start = 15)
ts.plot(x.ts, y.ts, col = 1:2, lty = 1:2)

legend("topleft", c("x", "y"), col = 1:2, lty = 1:2) # optional

Answer 3

您可以使用ggplot执行此操作：

z <- seq_len(60) # length of x
mydf <- data.frame(cbind(z, c(numeric(14), y),  x)) # bind together in df
                                                    # for ggplot
colnames(mydf) <- c("ob", "y", "x")
ggplot() + geom_line(data=mydf, aes(x=ob, y=x, color="red")) + 
  geom_line(data=mydf[15:60,], aes(x=ob, y=y, color="black")) + 
  scale_colour_manual(name="Series", values=c("red"="red", "black"="black"), labels=c("y", "x"))
