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))])

Hi Jim,
Thanks a lot for the response. I finally decided to do it with ggplot2
library, qplot and layers. It works pretty well, although I did not know how
to get the time working... so thanks!
Anoop

Hi,
I am trying to plot several columns in different graphs in columns and

The first column of my data file is the time, and the third is the
