I sent the announcement below to comp.newprod several weeks ago, and it
was never posted.  Also see the AD SHOWCASE in MacWeek, Jan 24, 1989.

At least two favorable reviews have been posted lately, which I will email
to interested parties.

WaveMetrics is proud to introduce Igor, a powerful graphing and data
analysis program for the Macintosh. Igor is designed for experimentation
with numeric data and production of publication quality scientific
and engineering graphs.

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 are printed 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.

	Graphs support zooming, panning, auto and manual scaling.
	
	Each graph can have its own cursors and cursor information panel
	providing dynamic readout of several quantities (including delta-X
	and delta-Y when two cursors are in use).
	
	Tick marks are always labeled intelligently even under pathelogical
	conditions.
	
	Most errors encountered during the execution of a user's macro
	can be corrected on-the-fly.

	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. It
requires version 3.2 or later of the Macintosh operating system
and supports MultiFinder including background processing.

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