5 - MENU COMMANDS
The following describes each of WinGraph's menu commands. For a
complete index and help with procedures and examples consult
the WinGraph Help System accessible through WinGraph's "Help" Menu.
GRAPH...
Invokes a dialog box where users enter equations for graphing.
Clicking the "Overlay" button invokes a secondary dialog box
where users enter another equation for simultaneous graphing
(two-dimensional graphing only).
Clicking the "Symbols" button invokes a dialog box containing a
table of symbols that WinGraph understands. This dialog box may
remain on the screen while users enter equations or invoke other
WinGraph features.
The "Plot Type" box contains "radio buttons" indicating type of
graph -- Cartesian or Polar.
REPLOT
Immediately invokes WinGraph's calculation functions. User's can
change multiple equation plotting parameters before plotting an equation.
Then, by choosing the 'Replot' menu option or clicking the 'Replot' button
on the button bar, the equation is recalculated and replotted using the
given parameters.
COPY
Copies the image presently displayed in WinGraph's main window to
the Windows clipboard.
Users can transfer images created in WinGraph to other Windows
applications supporting bit-mapped images.
Prints the image currently displayed in WinGraph's main window.
ABOUT
Invokes a dialog box identifying the WinGraph version number and
developers.
Clicking the "Info..." button executes Microsoft Windows Notepad
and loads "Wingraph.doc" which contains information about registering
WinGraph.
QUIT
Exits WinGraph.
RANGE...
Invokes a dialog box where users specify the solution range for
graphed equations.
The maximum solution range varies depending on two factors:
resolution, and graph type (2D or 3D).
ROTATE...
Invokes a dialog box where users swivel the viewing angle of
three-dimensional graphs.
Users can rotate graphs 360 degrees around each axis.
This option is not accessible for two-dimensional graphs.
COLORS...
Invokes a dialog box where users choose the colors in which
WinGraph draw graphs.
Users can specify different colors for drawing the graphs,
individual axes, and the background grid.
ZOOM...
Invokes a dialog box where users adjust the viewing distance of
three-dimensional graphs.
Users can "zoom" into or away from the image in WinGraph's main
window.
This option is not accessible for two-dimensional graphs.
RESOLUTION...
Invokes a dialog box where users select WinGraph's drawing
resolution -- Low, Medium, or High.
High Resolution is not available for two-dimensional graphs with
ranges greater than 12, or three-dimensional graphs with ranges
greater than 7.
Polar graphs are unaffected by this option.
AXES
Toggle's WinGraph's display of axes in the main window.
When checked axes are displayed or printed; when not checked axes
are hidden.
TEXT
Toggles WinGraph's display of equation text in lower right corner
of main window.
When checked equation text is displayed or printed; when not
checked equation text is hidden.
GRID
Toggles WinGraph's display of background grid for two-dimensional
equations.
When checked grid is displayed or printed; when not checked grid
is hidden.
COORDINATES
Toggles WinGraph's display of coordinate window in top right
corner of WinGraph's main window.
When checked coordinate window is displayed; when not checked
coordinate window is not displayed.
When checked WinGraph's cursor changes to a cross and the
coordinate window indicates the coordinates at the location of
the cursor.
This option is not accessible for three-dimensional graphs.
The coordinate window indicates (x,y) coordinates for Cartesian
graphs, and (radius, angle) for Polar graphs.
SOLUTIONS
Toggles WinGraph's display of solution window(s) in top right corner of
WinGraph's main window.
When checked solution window(s) are displayed; when not checked solution
window(s) are hidden.
If two equations are graphed simultaneously two solution windows
appear -- one for each graph.
When checked the system cursor changes to the shape of a cross.
User's can solve equations simply by clicking the left mouse button.
When the left mouse button is clicked WinGraph determines the solution
argument (the value placed in the variable) based on the location of
the cross in the window. WinGraph solves the equation with that solution
argument and displays both the solution argument and the solution to the
equation in the solution window(s).
If the equation contains an 'x' variable, WinGraph replaces 'x' with the
solution argument and solves for 'y' (or f(x)). If the equation contains
a 'y' variable, WinGraph replaces 'y' with the solution argument and
solves for 'x' (or f(y)). WinGraph determines the solution argument
based on which variable the equation contains and the location of the
cursor.
For Polar graphs WinGraph determines the angle where the cursor is
located and solves for the radius.
The solution window(s) indicate (x,y) coordinates for Cartesian graphs,
and (radius, angle) for Polar graphs.
This option is not accessible for three-dimensional graphs.
SYMBOLS...
Invokes a dialog box containing a table of Operators, Constants,
Functions, and Variables and the corresponding symbols that
WinGraph understands.
This dialog box can remain on the screen while users enter
equations.
SETTINGS
Displays the current values for WinGraph's graphing options. The
option values displayed are: Range, Resolution, Roll, Yaw, Pitch,
and Distance.
BUTTON BAR
Displays a context sensitive button bar at the top of WinGraph's plotting
window. The button bar provides easy access to most of WinGraph's
plotting features.

6 - DEFINITION OF SHAREWARE
Shareware distribution gives users a chance to try software
before buying it. If you try a Shareware program and continue
using it, you are expected to register. Individual programs
differ on details -- some request registration while others
require it, some specify a maximum trial period. With
registration, you get anything from the simple right to continue
using the software to an updated program with printed manual.
Copyright laws apply to both Shareware and commercial software,
and the copyright holder retains all rights, with a few specific
exceptions as stated below. Shareware authors are accomplished
programmers, just like commercial authors, and the programs are
of comparable quality. (In both cases, there are good programs
and bad ones!) The main difference is in the method of
distribution. The author specifically grants the right to copy
and distribute the software, either to all and sundry or to a
specific group. For example, some authors require written
permission before a commercial disk vendor may copy their
Shareware.
Shareware is a distribution method, not a type of software. You
should find software that suits your needs and pocketbook,
whether it's commercial or Shareware. The Shareware system makes
fitting your needs easier, because you can try before you buy.
And because the overhead is low, prices are low also. Shareware
has the ultimate money-back guarantee -- if you don't use the
product, you don't pay for it.

7 - DISCLAIMER - AGREEMENT
Users of WinGraph must accept this disclaimer of warranty:
"WinGraph 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 conse-
quential, which may result from the use of WinGraph."
WinGraph is a "shareware program" 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 WinGraph and continue to use
WinGraph after a reasonable trial period, you must make a reg-
istration payment of $35 to XWare, Inc. The $35
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 WinGraph must register and pay for their
copies of WinGraph within 30 days of first use or their license
is withdrawn.
Authorization will be automatically granted to distributors
recognized by the (ASP) as adhering to its guidelines for
shareware distributors, and such distributors may begin offering
WinGraph immediately (However XWare, Inc. must still be advised so
that the distributor can be kept up-to-date with the latest
version of WinGraph.). Non-ASP distributors must notify XWare, Inc.
of their intention to distribute WinGraph.
You are encouraged to pass a copy of WinGraph along to your
friends for evaluation. Please encourage them to register their
copy if they find that they can use it. All registering users
will receive a copy of the latest version of the WinGraph
system.

8 - OMBUDSMAN STATEMENT
This program is produced by a member of the Association of Shareware
Professionals (ASP). ASP wants to make sure that the shareware
principle works for you. If you are unable to resolve a
shareware-related problem with an ASP member by contacting the member
directly, ASP may be able to help. The ASP Ombudsman can help you
resolve a dispute or problem with an ASP member, but does not provide
technical support for members' products. Please write to the ASP
Ombudsman at 545 Grover Road, Muskegon, MI 49442 or send a CompuServe
message via CompuServe Mail to ASP Ombudsman 70007,3536.
