Function[xx,Through[{f[#[[1]]]&,g[#[[2]]]
&}[xx]]]/@{{x1,y1},{x2,y2},{x3,y3}} could do the trick.

Thanks very much for all the previous replies. Another simple question -
though I guess this will require more complex syntax. Suppose I have the
list,
data = {{x1,y1},{x2,y2},{x3,y3}}
and I want to produce the result (for fitting/plotting)
data2 = {{f[x1],g[y1]},{f[x2],g[y2]},{f[x3],g[y3]}}
I assume that if there was only one transform I wanted to apply, f[x],
then I could say
data2 = f[data]
but how about this more complicated transform with functions f and g?
again thanks! Your replies have been very helpful!
