This is Shareware and not Public Domain Software. Examine this free for
30 days and if you find it useful please send $15 registration to ATI.
When you register you will receive all updates and latest corrections
to the software and at least three months software support. You will
also make it possible for the program author to continue developing
quality software at reasonable prices.
** Please read the shareware agreement near end of this file and use the
registration form in file 'REGISTER' which also contains information
about other ATI software.

INTRODUCTION:
FDplot is an inexpensive scientific function/data plotting software
for the IBM-PC intended for high-school or college students and
instructors.
It is an alternative to expensive/complicated graphing packages and is
handy for general math/science, class and laboratory use.
FEATURES:
■ Menu driven, quick and easy to use. It will plot functions with
less fuss than most scientific graphing calculators.
■ No programming/compiling required - functions and data are entered
in BASIC syntax while the program is running.
■ Automatic selection of "nicest" integer graph scales to accomodate
all functions and data.
■ Includes paired statistics calculation.
■ Supplied with BASIC source code. => Menu is user expandable.
& Software can be custom modified by user.
COMPUTER REQUIREMENTS:
CGA, EGA, VGA or Hercules graphics and GWBASIC or QBASIC.
A hard drive is recommended.
INSTALLATION:
You can use the INSTALL.BAT which creates a directory on a hard disc
and copies the software to the directory.
Alternatively, at any time you can create a directory you want the
software in - example:
MD C:\USR\PLOT
and then copy the software files from diskette to directory
COPY A: C:\USR\PLOT
SETUP:
At least a CGA mono 640x200 monitor and graphics-card is required.
The included SETUP program will select various CGA, EGA and VGA
graphic modes.
You can experiment with the VMODE program to determine the graphics
capability if you don't know what it is. VMODE does not affect files,
only the video mode.
You can even edit T2.BAS (line 120) to suit your unique graphics card
(after using SETUP).
TO RUN THE SOFTWARE:
Just type MENU and make selection.
If you fail to define your functions or data properly you may get a
BASIC error message. In that case simply exit BASIC program and check
your PLOTF# and PLOTD# files.
OTHER INFORMATION:
A. ELLIPSA.BAS
The program has been included for calculating ellipsoid surface area
and is a part of the menu selection. If your institution has specific
programming needs please contact us for very reasonably priced custom
programming.
B. Plotting Notes:
(a) MS-DOS has a printer "GRAPHICS" command that permits you to print
screen graphics on a printer. After you use the dos GRAPHICS command
you can print the screen graphics on the printer anytime by pressing
the SHIFT-PrtSc keys. Make sure you have selected the right printer
with the graphics command. If it emulates the IBM graphics printer, no
printer selection is required after the GRAPHICS command.
(b) The program automatically selects the "nicest" axes and scales for
the functions to plot. It is possible to somewhat affect the graph
scales by selecting a special plot-data set made up of only two data
pairs which are beyond the limits of the functions - i.e. you can
define the diagonal corners of the graph. The program always defines
the axes/scales to accommodate the largest function and data given.
(c) For most cases just hit ─┘ for "function detail?" request. The
program estimates the optimum plot step size. There may be occasional
cases where the function graph looks too ragged. In that case RE-PLOT
the function and choose a number between 0 and 1.0 (the higher it is
the more detail). Alternatively if it takes too long to plot choose a
lower number between 0 and -1.0.
(d) Besides the regular BASIC functions (trig, expon, log, etc.) PI
is defined as 3.1416 and can be used for function definition (only).
C. Plot Data Definition.
Again follow directions to define data for plotting. Data is stored in
ascii file "PLOTD".
If you wish to write these files with an ascii editor their format is
as
Ascii file:
┌────────────────────┐
line 1 │N │ N= # of data sets.
line 2 │X1,Y1 │ data pair separated by comma.
line 3 │X2,Y2 │ .
line 4 │X3,Y3 │ .
. │ . │ .
. │ . │ .
. │ . │ .
. │XN,YN │
last line │ -2 │ -2 OR correlation value for statistics.
└────────────────────┘
D. Paired statistics program.
For N (X,Y) pairs it calculates mean, SD, variance, correlation,
covariance, and Linear Regression slope and intercept.
The data is stored in the ascii file PLOTD in format as above in C.
E. MENU.BAS Program
You can easily add to the menu program by inserting new lines between
lines 1000 and 1520. Do not delete line 1520 "EXIT"," " since the
program looks for it. The format of these lines is
<line number> DATA "<purpose description>","<program name or list filename>"
Line number is any from 1000 to 1499. Program names should have full
extensions - examples: STAT.BAS, EDIT.EXE, MEM.COM.
DISCLAIMER and SHAREWARE - AGREEMENT:
Users of FDplot must accept this disclaimer of warranty: FDplot is
supplied as is. The author disclaims all warranties, expressed or
implied, including, without limitation, the warranties of
merchantability and of fitness for any purpose. The author assumes no
liability for damages, direct or consequential, which may result
from the use of FDplot."
FDplot is "shareware software" and is provided at no charge to the
user for evaluation. Feel free to share it with your friends, but
please do not give it away altered or as part of another system. The
essence of "user-supported" software is to provide personal computer
users with quality software without high prices, and yet to provide
incentive for programmers to continue to develop new products. If you
find this program useful and find that you are using FDplot and
continue to use FDplot after a reasonable trial period, you must
make a registration payment of $15 to Abri Technologies. The $15
registration fee will license one copy for use on any one computer at
any one time. You must treat this software just like a book. An
example is that this software may be used by any number of people and
may be freely moved from one computer location to another, so long as
there is no possibility of it being used at one location while it's
being used at another. Just as a book cannot be read by two different
persons at the same time.
Commercial users of FDplot must register and pay for their copies of
FDplot within 30 days of first use or their license is withdrawn.
Site-License arrangements may be made by contacting Abri Technologies.
You are encouraged to pass a copy of FDplot along to your friends
for evaluation. Please encourage them to register their copy if they
find that they can use it. All registered users will receive a copy
of the latest version of FDplot and at least three months software
support.
