If you represent your series as zoo series then you can do this: library(zoo) z <- zoo(cbind(a = 1:3, b = 4:6, c = 3:1, d = 6:4)) xyplot(z, screen = 1, type = c("p", "p", "l", "l"))
See the three vignettes that come with zoo and also see ?xyplot.zoo If you omit screen = 1 then the 4 will be on separate graphs.
