Graf 2 v2.3.6
-------------
メIf this program proves useful to anyone out there then fine, if not then that's fine too.モ
Graf 2 is a scientific X-Y plotting and simple model fitting application that I have developed over
the years as my needs required. It features a fully parametric plotting engine that
interprets TEXT data files that can be in fairly free form. Lines of text that don't begin
with numbers are ignored and any non-numerical character (ie the ususal tab or even
commas or simple letters) can act as column separators. Graf knows about linefeeds
and even fortran double precision 'd' notation, so it can plot output directly from
many sources. It also support publish/subscribe and works well with Excel.
Large data files load almost immediately, and are limited only by RAM constraints.
Any number of curves from any number of data files can be independently drawn in a plot.
Linear curve fitting of various polynomials and simple statistics are available as well.
Best of all it is *free*, and Graf may be freely distributed, or distributed at cost
of materials and delivery (but not sold or resold).
v2.3.6 fixes a number of bugs that slipped into 2.3.4 and 2.3.5. Please don't use 2.3.4 or 2.3.5.
Some bugs with fitting routines have been addressed, and new statistics files are included in
the examples. Again, it would be best if older statistics files from earlier versions of Graf
were not used - although it will mostly be OK. It is best to make new stat windows and
generate new stats. v2.3.6 has been verified to startup without crashing on a mac Classic
and no longer needs quicktime to open files.... :) A number of other bugs with the
statistics fit preferences have been ironed out.
New for 2.3.4,5,6:
------------------
Global interface and file system overhaul. (Spring cleaning!) New Least-Squares features.
New text search and replace features. This series is the last major Graf 2 enhancement.
(Bugs fixes will continue though.)
v2.3.x will probably be the last version of Graf to support B&W only (MC68000)
machines like the mac plus. :( However, the planned improvements for the next
version (Graf 3), including 3D plotting (with hidden polygons and RGB lighting) and more
advanced analysis like FFTs, will not be practical on older machines anyway. I hope that
v2.3.x will be around for a while - I will continue to support it even after Graf 3 is released :)
so users with more modest machines and needs can still make plots for free!
I don't have access to a Mac Plus anymore, so I would be interested in test
reports and bugs from B&W mac users.
