People, I want to create seven plots on the one graph - each with it's own Y axis and scale - I want the plots overlaid because it is the shape of the graphs that I want to compare, not so much the values. I have found examples where people show how to put two Y axes on the left of the plot but I couldn't find examples of any more than that - is it possible? Thanks, Phil. -- Philip Rhoades GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil at pricom.com.au
Dear Philip, If the values are not important, then you don't need different Y-axes. Why not standardise the seven datasets so they have a common scale?

Jim
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!
