Hi Ogbos,
Hope things are going well for you. Perhaps this is what you want:
date_x1<-seq(as.Date("1953-01-02"),as.Date("2006-11-15"),length.out=8)
value_x1<-sample(1000:5000,8)
date_x2<-seq(as.Date("1957-07-26"),as.Date("1994-07-17"),length.out=6)
value_x2<-sample(0:1000,6)
plot(date_x1,value_x1,type="b",col="red",xlab="Year",ylab="x1",
ylim=c(0,max(value_x1)))
points(date_x2,value_x2,type="b",col="blue")
