I've been using, very satisfactorily, two programs from Interactive
Microware. 

Scientific Plotter Version II lets you plot x,y pairs, with or without
error bars, or y values at a constant x interval.  The axes are set by
the user, there is no autoscaling, so if you plot different sets of
data, they can be compared by looking at them.  There is a variety of
point styles to choose, and connected lines are optional.  Axes can be
labeled.  Axes markings spacings are selected by the user.  It saves
the hi-res screen to disk for printing by a graphics program, or you
can dump it if you have a Grappler or Pkaso card.  PRICE IS $28 !!!
Color plotter adaptations for pen plotters are available for $28 extra.

For fitting curves to data, there is a separate Curve Fitter proram.
It does autoscaling of axes, and fits 1-6th order curves, by least
squares, or does interpolation using cubic spline, Stineman, or
polunomial.  Exponential and geometric fits are supported.  
PRICE IS $39 !!!

Both programs save their data as text files, and you can import data
from each other.  Fitted curves can thus be overlaid on the data points in
the Scientific Plotter program.  Applesoft programs can write out data
files in the format compatible with these plotter programs, for
automatic entering.  (Data can be entered from disk, keyboard, or
sensor input by writing an Applesoft data subroutine into the program.)

If you need a graphics dump program, they sell the Advanced GrafPak
printer utility, from Smartware. This supports many printer cards and
printers.  Price is $35.

They make similar products for the IBM's also.
