 Hi all:
Was this question ever answered?

#Is it possible to have different axis limit for each facet in a ggplot2 plot? Here is an example
library(ggplot2)
x=seq(-10,10,.1)
y=cos(x)
z=sin(x)*10
dat=melt(data.frame(x,y,z), id.var="x")
qplot( x, value, data=dat, facets=variable~., geom="line" ) + scale_y_continuous(limits=c(NA,NA))


#Both the x and y axes are now the same for both facets. But since the ranges of the 'y'
# and the 'z' variable differ so much, I would prefer their y axes to be different. This is easy to do in 'lattice':

library(lattice)
xyplot( value~x | variable, data=dat, type="l", layout=c(1,2), scale=list(y="free") )
