Hmm.. this how my code looks like inside my function
plot(density(100*datalist[[1]]$dataset$Utilization), xlab="Overall utilization
[ % ]", main="", ...)
colorList=colors()[seq(10,100,10)]
colorList[1]="black"
if (length(datalist) > 1) {
for (i in 2:length(datalist)) {
lines(density(100*datalist[[i]]$dataset$Utilization), lty=i, col=
colorList[i])
}
}
given on input a datalist the code above just by reading element by element of
the list adds the corresponding line(..)
I fail to see how I can calculate the min and max and then call the first plot
with the right lim.
Could you please help me?
Regards
Alex

Hi Alex,
One way or another you are going to have to set the limits in your first call
to "plot". You could do the plot first and collect the limits along the way,
then do it again, but I can't see that this has any advantage over calculating
the limits for the entire set of data that is to be plotted at the beginning
and then doing the plots. If you want to get the limits for each data set
separately, maybe:
range1<-range(x1)
range2<-range(x2)
range3<-range(x3)
ylim<-range(c(range1,range2,range3))
However, I suspect that this is of more use in helping you understand what is
happening than actually getting it done.
