[I tried to reply to the original poster, brucem@merlin.MIT.EDU, but my
mail bounced.]

Also check out Igor, a graphics program from WaveMetrics for the Mac,
which is specifically research-oriented and provides publication-quality
graphs.

MacWeek favorably reviewed Igor in their April 18, 1989 and July 11, 1989
issues.  WaveMetrics recently released version 1.1 that added capabilities
not covered in the reviews.

Here are some unique features of Igor.
    - It is FAST. Graphs are updated almost instantly.
    - Number and length of data sets are limited only by available memory.
    - Each variable and data array can individually be single or double
      precision, real or complex.  
    - Imports data via text files or via the clipboard. You can also
      synthesize data using mathematical expressions.
    - Graphs can contain any number of data sets, each with it's own color
      and line style (including true dashed lines).
    - Graphs print at the highest available resolution of your printer.
    - You can print multiple graphs per page, overlay graphs and print
      poster-sized graphs.
    - Supports linear, log/log and semilog graphs with up to four axes per
      graph.
    - Labels and annotation can use sub/superscripts and any combination
      of fonts, sizes and styles.
    - Data analyses include:
        + Manipulation of data with straightforward mathematical
          expressions which can draw upon more than 80 functions.
        + Linear curve fitting to lines & polynomials; non-linear
          fits to sines, exponentials, double exponentials, Gaussians
          and Lorentzians.  Igor can automatically provide initial
          coefficients for the non-linear fits.
        + FFTs and IFFTs on real and complex data.
        + Smoothing.
        + Histogram generation.
        + Integration and differentiation.
        + Descriptive statistics.
        + Searching and sorting.
        + Very powerful and flexible waveform arithmetic.
    - All operations can be invoked from dialogs, from structured macros
      or from a command line.  You can write a simple macro to load your
      data from a file, make a graph with styles of your choice and
      print the graph.

Igor runs on a Mac Plus, SE, II or IIx. It requires a minimum of two
floppy drives and 600K of available memory. It supports the 68881
math coprocessor, color, large screens and multiple screens.

Igor is available immediately from WaveMetrics. The single quantity
price is $195 plus shipping. Quantity discounts and site licenses
are available.

Disclaimer:  My only connection with WaveMetrics is that some friends of mine
             work there and I have a copy of Igor.  QTC has absolutely no
	     connections with WaveMetrics, that I know of.
