cex.main .lab .axis etc. are relative so yo need for your case to
specify something like cex.axis=1/5
Not sure why you are using keys of 1-4 when you've already given nice
labels. I tried
labcurve( list( One= list( x,sin(x)), Two= list( x,cos(x)),
Three=list( x,(x*x)), Four= list( x,exp(x)) ),
pl=TRUE )
and got some nice output after reducing cex.*
