CRVPLOT is a general purpose data plotting and curve
fitting program. It was developed by and for engineers and
is known for its ease of use and power.
Data is entered into tables as in popular spreadsheet
programs and, like spreadsheets, it has a powerful data
manipulation capability where columns of data can be
manipulated, scaled or normalized using complex
mathematical functions. Using this feature, new columns of
data can also be generated that are mathematical functions
of other columns.
In addition, CRVPLOT has a powerful and flexible text file
reading capability that allows reading data from many
sources.
Especially popular with engineers & scientists are the
multiple axes capabilities (where up to 5 "X" and/or "Y"
axes can be included) and the ability to put up to 40
labels (of 40 characters each) anywhere on the plot.
The complete program is included in a single file which
makes installation trivial (and optional!). It loads fast
and requires very little disk space (360K).

CRVPLOT is a shareware product. It is not free. Both the
program and the manual are copyrighted and may not be copied
without written permission. The only exception to the above is
that the program (not the documentation) may be copied and given
to others for evaluation purposes. Anyone continuing to use
CRVPLOT must register the program. The registration fee is $45
(price subject to change without notice) and includes a disk
with the latest version of the program, a copy of the users
manual and occasional newsletters announcing enhanced versions,
unique techniques etc. Ohio residents add 5.5% sales tax.

CRVPLOT / QUICK REFERENCE
-------------------------
STARTING THE PROGRAM:
--------------------
When current drive contains "CRVPLOT.EXE", enter
"CRVPLOT".
A SIMPLE PLOT:
-------------
After starting the program:
(1) To enter data to be plotted, hit "1" from the
main menu to go to data table #1.
(2) Enter the "x" data in column 1 & the "y" data
in column 2. (see "Keystrokes" & "Data Entry"
below if necessary, use data values between 0
and 10 - see "Grid Definition" below).
(3) Hit "F10" to return to the main menu.
(4) Hit "D" to display the plot.
(5) When done viewing the plot, hit a carriage
return to return to the main menu.
To change the grid, hit "G" to go to the Grid menu.
To change the way the data is plotted, hit an "S"
from the Main Menu to go to the Specify Curves Menu.
KEYSTROKES:
----------
When a single keystroke is adequate to proceed, a
carriage return is normally not required. When the
cursor is in a data entry cell (a highlighted
portion of a line), you can enter data or text, as
appropriate, and the following keys can usually be
used:
Home Move to the left end of the cell.
End Move to the right end of the cell.
Ctrl-rightarrow
Move 7 character positions right within
the cell.
Ctrl-leftarrow
Move 7 character positions left within
the cell.
Ctrl-End Erase from current cursor position to
the end of the cell.
Ins Moves everything from the current cursor
position one character space to the
right (the last character on the line is
deleted).
Del Deletes the current character and moves
everything to the right of the cursor
one character position left.
The program response to other keystrokes depends
upon the context. Typically:
left/ Moves to the next character position
right left/right. If that would be out
arrow of the cell, will move to next cell
in that direction.
downarrow Moves to next cell down.
uparrow Moves to next cell up.
carriage return
Same as downarrow.
PgUp Previous page.
PgDn Next page.
F10 Return to previous menu.
Tab/ Moves to next/previous horizontal cell.
Shift-Tab
DATA ENTRY:
----------
When making an entry into a cell, if the FIRST
keystroke after entering the cell is not a right
arrow, the entire contents of the cell will be
erased.
Any action to leave a cell (EXCEPT an Esc) causes
the value entered to be retained.
DATA TO BE PLOTTED:
------------------
All data is stored in tables. Tables can be
entered from the Main Menu by entering the table
number (e.g., 1 or 2 etc) or by entering an "*"
(the program will then ask what table you want to
enter).
Use the Specify Curves screen to identify, for each
curve, what table/column is to be used for the
X-data and what table/column for the Y-data. If
the TABLE for the X-data is "0", no data will be
plotted for that curve.
To plot symbols only, use Line Style "0". To plot
the line only, use Symbol "0".
The same data can be plotted several times on the
same plot (e.g., to compare second and third degree
polynomial fits). In this case one usually sets
the Symbol to 0 for all but one of the curves.
MATHEMATICAL DATA MANIPULATION:
------------------------------
In any data table, the F7 function (GenCol) allows
mathematical data manipulation much like a
spreadsheet. Examples:
To scale data in table 4, column 3: D43=9/5*D43+32
To create data in table 2, column 4 as a function
of the prior three columns: D24=(D22-D21)/1000+D23
TEXT INFORMATION:
----------------
To individually locate labels or text information
on the plot, use the Specify Curves screen and
enter text information in the Labels column. The
text data is NOT in any way related to the curves
specified on the same line.
Text information can be located using a cursor if
the "X LOCation" of the label is specified as "C".
When the program is ready to put the label on the
plot, a note will appear on the upper left of the
screen and a cursor appear in the middle of the
screen. Position the cursor (with arrow or
shift-arrow keys, or mouse) and hit Enter when
ready. You will be given an opportunity to
re-position the label.
GRID DEFINITION:
---------------
To define the grid to be used, use the Grid Menu.
This menu is used to define the type of grid, the
axis limits, the number of major and minor
divisions along the axis, the plot title(s) etc.
VOID REGION/NOTE BLOCK:
----------------------
From the Main Menu, hit the "N" key to enter the
Notes Screen. On this screen, a void region can be
defined where the grid will not be printed. Often
the note block is positioned within the void region.
CURVE FITTING:
-------------
The curve fit type is requested on the Specify
Curves menu under the "Fit Type" column. When the
cursor is in that cell, the fit types are shown on
the bottom of the screen. The fit information will
be made available after the plot has been displayed.
HARDCOPY:
--------
Obtaining hardcopy is dependent upon the graphics
device you have. If you have an Epson compatable
printer, hit the "P" key when the plot is displayed
and the screen will be dumped to the printer. If
you have an IBM Proprinter compatable printer, hit
the "G" key. To use other printers/plotters, use
the "C"hange Graphics Device option from the main
menu to select the device, then use the "D"o Plot
option to send the plot to the device.
PEN PLOTTER SETUP:
-----------------
For a pen plotter connected to a COM port, the
settings must be 9600 baud, 7 data bits, 1 stop
bit, no parity.
