Try something like:
par(mar=c(4,2,1,12),tcl=0.2,mgp=c(1,0,0))
plot(1:10,1:10)
for (i in 1:7)
{
par(new=TRUE)
plot(1:10,(i+(1:10)+rnorm(10,0,0.4)),yaxt='n',col=i,type='l')
axis(4,line=(i-1)*1.5,col=i-1,col.ticks=i-1)
}
You may need to tweek around the options a bit and check that the tickmarks are
actually labelling the correct axes and that the colors correspond....I did not
check this thoroughly!
