Subject:  a transformation required


I want to be able to plot f(x) for x in the range [-infinity..infinity],
likewise f(x) in [-infinity..infinity]  on a square screen.  What I need is a
suitable transformation to map this range onto a finite range which yields a
reasonable scaling.  Something like  x / abs(exp(x)) ?
Any suggestions?
