[R] Vertical Labels in plot graph - normally working fine but not on this graph

[Alexander Engelhardt]

Hey,

from what I see, you try to use the par(las=3) function after the plot 
command. You should use it before it, though. Somewhat liek this:

ExtAvgCWV = rnorm(200)
ExtAvgDemand = rnorm(200)
ExtGasDays =   seq(from = as.Date("2010-8-4", "%Y-%m-%d"), along.with =
ExtAvgCWV, by = "days")
op <- par(las = 3)
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(op)

X11() ## windows()
op <- par(las = 3)
plot(ExtAvgDemand, ann=FALSE, xaxt="n", yaxt="n" )
#dev.set(which = 4)
axis(side =1 , at = tickplaces, labels = Labels)
par(op)
