Would it be possible to change the axis at the end?
My data sets seem to be quite large so I was thinking for the plot and the consequent lines to keep always 
the current minimum and maximum like
 
plot(x)
minimum=min(x)
lines(x1)
minimum=c(minimum,x1)
lines(x2)minimum=c(minimum,x2)
then if there is a good way for altering axis lines I could put the limits I want to.
 
Regards
Alex

Hi Alaois,
Try this:

ylim=range(c(x1,x2,x3))
plot(x1,ylim=ylim,type="l")
lines(x2)
lines(x3)
