The ylim option in the hist function should do what you need .... A simple example with 2 sets of data .... # Create Data set.seed(123) d1 = 7*rnorm(100) d2 = runif(100) par(mfrow = c(2,1)) hist(d1, ylim=c(0,50)) hist(d2, ylim=c(0,50)) HTH Pete -- View this message in context: http://r.789695.n4.nabble.com/How-to-change-the-scale-of-the-Y-axis-tp3883843p3884112.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
