Doesn't Excel work for this?
If not, I use a simple one called Grafdemo.exe which is
best for plots up to 150 data points *and* has curve
fitting SW for smooth displays and approx formulas.
Or, Computer Calculus 4.0 CC4 which plots 2D and surface
plots
CC4 has good presentation of 2D with maxima *plus* you can
rotate all the axes around for best view.
Both have a good price - free.
