Hi Naresh,
You could calculate the ranges explicitly and then supply to scales():
holdRange <- vector('list', length(unique(my.df$name)))
for(i in 1:length(holdRange)){
holdRange[[i]] <-
rev(range(my.df$x[my.df$name==unique(my.df$name)[i]]))
}
holdRange
# [[1]]
# [1] -5.052890 -9.967671
# [[2]]
# [1] 2.648870 -2.629866
xyplot(y ~ x | name, data = my.df,
type = c("p", "g"),
scales = list(relation="free", limits=holdRange))

I want to draw a lattice graph where different panels have different ranges AND
the order of values is reversed. I am struggling to achieve both at the same

Thanks,

# This does not work as intended. x and y values are in reverse order. But
both panels have the same and x and y ranges. scales argument does not seem to
have any effect.
xyplot(y ~ x | name, data = my.df, xlim = rev(range(my.df$x)), ylim = rev(range(my.df$y)), scales = list(x =
"free", y = "free"), type = c("p", "g"))
# This does not work at all. panel.xyplot does not see to take xlim or ylim
arguments.
xyplot(y ~ x | name, data = my.df, scales = list(x = "free", y = "free"), panel
= function(x,y,subscripts, ...) {
panel.xyplot(x,y, ylim = rev(range(y[subscripts]), xlim =
rev(range(x[subscripts]))))
})
