Try this: set.seed(123) x <- 1:5 y1 <- rnorm(5) y2 <- rnorm(5) par(mar = c(5,4,5,4)) plot(x, y1, xlab = "x-axis", ylab = "y-axis", type = "l") par(new = TRUE) plot(x, y2, axes = FALSE, yaxs = "i", type = "l", ann = FALSE, col = 2) axis(4, las = 2) mtext("z-axis", 4, 2)
I hope it helps. Best, Dimitris On 3/1/2012 9:13 AM, Alaios wrote:
Dear all, I would like to place into a same plot two plots. Their y values though are different a lot (first series has around -100 y values and the second one slightly over 1). The x value are the same. I would like to have in the same plot (under the same x,y axis the two plots). Is it possible then to have two y labels, one for example in the left side and an extra y label at the right. Each y label will have its own labeling and its own Font type line. CAn I do something like that in R with the normal plots and lines? I would like to thank you in advance for your help B.R Alex [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
