Hi Anoop, Not sure whether it's too late for you, but is this along the lines of what you want?:
x<-0:1000 y<-sin(x/500)+rnorm(1001)/10 z<-cos(x/500)+rnorm(1001)/100 plot(x,y,col=rgb(1,(z-min(z))/(max(z)-min(z)),0)) Or possibly like: plot(x,y,col=rainbow(256)[255*(z-min(z))/(max(z)-min(z))]) Mind that the binning could be done a bit more conscientious ;) Hope it helps, Tsjerk On Wed, Feb 9, 2011 at 6:30 PM, anoopmj <anoo...@gmail.com> wrote: > > Hi Jim, > > Thanks a lot for the response.
