Hello, I wonder if someone can elaborate on why in the first graph I am able to set labels vertical to the x-axis but not in the second.
I tried to select the window but it didnt really help. Many Thanks Paolo ExtAvgCWV = rnorm(200) ExtAvgDemand = rnorm(200) ExtGasDays = seq(from = as.Date("2010-8-4", "%Y-%m-%d"), along.with = ExtAvgCWV, by = "days") plot(ExtAvgCWV, ann=FALSE, xaxt="n", yaxt="n" ) tickplaces <- seq( from = 1, by = 21, to = length(ExtGasDays)) Labels = ExtGasDays[tickplaces] axis(side =1 , at = tickplaces, labels = Labels) par(las = 3) windows() plot(ExtAvgDemand, ann=FALSE, xaxt="n", yaxt="n" ) #dev.set(which = 4) axis(side =1 , at = tickplaces, labels = Labels) par(las = 3) [[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.
