0.1. YOUR EVALUATION COPY
A Note About Your Evaluation Copy
At several places in this copy of the User's Guide you'll see the
following notice.
**************************************
* Omitted from the evaluation copy *
**************************************
We honestly feel that we've supplied enough of the manual to
allow you to make a good evaluation of the program. There are
several reasons why we didn't provide the entire manual on disk.
* We'd like to encourage more of our users to pay for the
product. We've priced our software so that you can afford
it. Frankly, it's the best bargain in the industry. We also
suspect and hope that you (the buying public) will want to
cast your "vote" for lower priced software by paying readily
for such programs. Other software publishers would then be
forced to take notice.
* We feel that the honesty of our "registered" users should be
rewarded. They're entitled to some extra value that should
rightfully be denied to those who don't pay.
* It takes up too much room on the diskette.
We trust that you'll be open-minded about the omissions. We hope
that we can soon add you to our list of very satisfied customers.
The printed copy of this manual is over 55 pages long.

1. INTRODUCTION
1.1. GENERAL INFORMATION
PC-Graph is a program that allows you to plot database and report
files which have been created by PC-File. It has been designed
specifically for ease of use and understanding.
With PC-Graph you can see your data very quickly, giving you a
perspective that reports cannot (a picture is worth a thousand
words!!). With PC-Graph you can:
- Produce line graphs of Report files or Database files (up to
1000 records)
- Define the area on the screen to use for your graphs
- View all or portions of your data
- Put labels and comments on your graphs
- Save graphs to disk
- Print your graphs
Any database or report file that has been created with PC-File
may be graphed using PC-Graph. Many types of files created by
other programs (such as VisiCalc) may be imported into PC-File
and then graphed using PC-Graph.
Above all else, PC-Graph is easy to use. Most people have been
able to use it with no training or instruction. We developed
this program with you in mind, trying to give you the most
desirable features without making it overly complex. You will be
"seeing" your data, the way you want to see it, moments after
creating it with PC-File.
Any suggestions which you have for improving this program will be
thoughtfully considered and greatly appreciated.
SYSTEM REQUIREMENTS:
- 192k IBM-PC computer
- IBM (or IBM "compatible") Color/Graphics Monitor adapter
- Graphics monitor
- PC-File III database program
- An IBM graphics printer (or compatible) is recommended.

1.2. GETTING STARTED
Before trying to operate PC-Graph:
- Please carefully read this User's Guide
- Put a write protect tab on your PC-Graph diskette, so that it
can't be accidentally erased or overwritten.
- Make a copy of your disk and use the copy to run PC-Graph.
Assuming you have a two-drive system, these are the steps to
follow:
1. Put your DOS system diskette in the "A" drive, and a blank
diskette in the "B" drive.
2. If you don't have a DOS prompt on your screen, then boot-up
the DOS operating system in the usual manner. If you do not
know how to do this, refer to your DOS manual for
instructions.
3. Make sure you are defaulted to the "A" drive. To do this
type "A:" (do not type the quote marks) and press the (enter)
key.
4. Format the diskette in the "B" drive as a system diskette.
This is done by typing:
FORMAT B:/S
Caution: any data currently on the "B" diskette will be lost.
5. Remove the DOS diskette from the "A" drive.
6. Put the PC-Graph distribution diskette in drive "A"
7. Copy the PC-Graph files to the "B" disk by typing:
COPY A:*.* B:
8. Remove the diskette from the "B" drive and label it as your
PC-Graph diskette.
9. Put a write protect tab on your new PC-Graph diskette, so
that it can't be accidentally erased or overwritten.
10. Store your PC-Graph distribution diskette in a safe place.
Now that your program is backed up and your original is safely
stored away let's explore what can be done with PC-Graph.
_
2. TUTORIAL
We have included some sample files on your PC-Graph diskette for
tutorial purposes. This section will show you how to create a
plot, label it, save it and bring it back, using some of those
files. This tutorial is meant to take you by the hand through
most of the options. It won't go into a great deal of
explanation of those options or their features. If you want a
more detailed description, please refer to the PC-Graph Options
chapter.
2.1. PREPARATION
- Put your backup PC-Graph diskette in the A: drive
- Set default to your A: drive by typing "A:" (no quotes) from
a DOS prompt
- Type "pc-graph" (no quotes) and press the (Enter) key
- Enter "A" (no quotes) in response to "... default drive
[A-H]"
- Enter the appropriate response to the question on printer
type
- Now you will see the Main menu appear
_______________________________________________________________
F1 - Plot data F2 - Save plot to disk
F3 - Load plot from disk F4 - Print screen
F5 - View menu F6 - Label plot

______________________________________________________________

Page 8. PC-Graph User's Guide
2.2. PLOTTING
Press the F1 key (Plot data) and you should see the light on
drive A: come on. PC-Graph is building a list of all available
files and will present it to you when it's complete. The screen
will look like this:
_______________________________________________________________
Which file do you want to plot:
TUTOR1
TUTOR2
9-Menu
_______________________________________________________________
Type "tutor" (no quotes).
You will hear a beep and get this message:
entry not unique.... re-enter. Press any key to continue.
You got this message because PC-Graph was not able to uniquely
identify which file you wanted from the list. Press any key and
let's try again.
Type "tutor1" (no quotes).
You now have a list of available fields to plot. Some of them
will not be meaningful to plot. Only numeric fields can be
plotted; anything else will result in meaningless data (PC-Graph
will still try to plot it though).
_______________________________________________________________
Which field do you want plotted:
payee
amount#
_
PC-Graph User's Guide Page 9.
9-Menu
_______________________________________________________________
Notice that on the bottom row there is the number of a function
key displayed, followed by a word. The bottom row will almost
always display the active options you have (that's ALMOST always
because one option you have is to NOT display your options).
Whenever "9-Menu" is active, you may use it to get back to the
main menu. In fact, to get to some options you may find that you
need to go through the main menu to get to them.
Now type "amo" (no quotes).
Notice that you didn't have to enter the entire field name. With
both file names and field names, you only need to enter enough of
the name to uniquely identify it.
Now the screen will blank, the A: drive will start spinning and
you will get a new display:
_
Page 10. PC-Graph User's Guide
_______________________________________________________________
Report: TUTOR1
Field : amount#
number of data points = 17
maximum value = 205
minimum value = 6.63
9-Menu
_______________________________________________________________
Your data is being read in and the values are displayed on the
screen as PC-Graph reads them. The display is there to remind you
of the choices you made, and to let you see some activity so you
know something is happening.
If you want to be adventurous, you may press the F9 key (your
only active option) and see what happens. If you do that, just
follow the steps above to get back to this point (we'll wait for
you)......
After all the points have been read in (about 90 in this file),
you will see the CONFIGURATION MENU. You will also notice a
cursor positioned in the first field (Top edge of plot). The
cursor is moved by pressing the [tab], [arrow] or [enter] keys.
Move the cursor to the Grid field by pressing the [enter] key 4
times. Now type "N" (uppercase or lowercase).
Move to the Axes field by pressing the [down arrow] key (you
could have used [enter] but we are exploring). Type a "Y".
You told PC-Graph to plot using the following area on the screen:
The top of your plot will be at -- line 5
The bottom of your plot will be at -- line 20
The left edge of your plot will be at -- column 2
The right edge of your plot will be at -- column 78
You just told PC-Graph where on the screen you wanted the plot
located and how much space it should take up. You could make it
very small (rows 15 to 17, columns 40 to 45 for example) or very
_
PC-Graph User's Guide Page 11.
big (rows 3 to 22, columns 2 to 78 -- this is the maximum size).
You also indicated you wanted PC-Graph to place Axes in your plot
(you may have Axes or Grid or Neither, but not both) and not to
draw a box around your plot.
Later, you can read more about these parameters in the Plot Data
section. Let's move on for now.
Notice your active options at the bottom of the screen.
Now press F10.
You will now see another menu; the VIEW MENU.
The view menu lets you create the window, or view, of your data.
With it, you tell PC-Graph how much of the data you want to look
at.
The cursor is moved the same way as in the previous menu.
Position the cursor to Minimum y-value and type "20". You are
telling PC-Graph that the bottom of your plot will represent a
value of 20. Points that have a value less than 20 will not
appear in the plot.
Press the [enter] key.
Now type "22222".
Whoops! Let's say we didn't really mean "22222". Just press the
[backspace] key (the key just above the [enter] key) five times
and use the [space bar] to clear out the 2's. The field will be
cleared now (that means the maximum y-value displayed will be the
maximum y-value read in -- see Maximum y-value in the Plot Data
section).
Now you know how to enter data into fields, how to make mistakes
and how to undo them, so let's see the plot.
Press the F10 key and your plot will be drawn on the screen.
_
Page 12. PC-Graph User's Guide
It should look like this:
PUT TUTOR1 PLOT HERE
Notice that after the plot gets drawn there is some disk
activity. PC-Graph is saving temporary information about the plot
that will be used later if you decide to go into Label Mode
(we'll do that soon). While saving, all the options are turned
off (you are stuck here) until the copying is complete. You may
continue when the active options are again displayed on the
bottom row.
Let's say after all this, that you've decided you want all the
data displayed (remember we left out points that had a value less
than 20).
Press F5. This will take you back to the View Menu. The entry
that you made before is gone (View Menu will load the fields from
a default file if you create one). In fact, all the fields are
empty (unless you created a default file by running this tutorial
before).
If all the fields are empty press F10. If not, you may blank them
_
PC-Graph User's Guide Page 13.
out by moving the cursor to each field. Either use the [space
bar] to blank them out, or the [backspace] and [del] keys. When
the fields are clear, press F10.
Now you have the plot back. See the difference? You now have ALL
the points plotted on the screen.
Also notice your active options. You may activate any of these
simply by pressing the appropriate function key. Don't press
anything yet though. Some of the keys will cause you to lose your
graph and we don't want to do that yet. Before going on to
labelling, let's try one more thing.
Press F5. This will get you back to the View Menu.
Now let's enter some numbers. As this is only a tutorial, let's
be a bit daring!
For minimum x-value, enter -20 (that's right -- minus 20)
For maximum x-value, enter 100
For minimum y-value, enter -100
For y-axis spacing, enter 50
No entries are made for maximum y and x-axis spacing
Now enter a "Y" for Save for this file
Press F10 and see what you get. We wanted you to see what
happened if you "Saved for this file".
When your options are active again, press F5 and see what you
get!!
This time the fields have the entries you made before. In fact,
they have been stored on your default disk in a file called
TUTOR1.VUE. Whenever you plot this file the answers in the view
menu will be defaulted with these entries. You may change them
and re-save the file if you'd like. Later, you may delete the
file from the disk using DOS. The file is not required.
Now clear all the fields and press F10 so we can get on with
labelling.
_
Page 14. PC-Graph User's Guide
2.3. LABELLING
Press F6. This will put you in the label mode. A message will
appear at the upper left corner indicating that you are in label
mode. It will disappear when you press any key. Press any other
key except an active function key to get rid of the message.
Now let's learn how to move the cursor, enter text, and correct
mistakes.
There are several keys that allow you to move the cursor without
affecting the graph: the [arrow] keys and the [tab] key (shifted
and unshifted).
Let's try the [arrow] keys.
Try pressing the [down arrow] key several times. If you get the
number 2 instead of moving down, then press your [num-lock] key.
You can delete the 2's by pressing the [backspace] KEY or the
[del] key. Then press the [down arrow] key several times again.
This time you will move down.
Now press the [scroll lock] key (upper right corner of keyboard)
and press the [down arrow] key several times again.
Using the [scroll lock] key you can cause the cursor to move an
entire character space each time you press it, or 1/8 of a
character space. Play with it for a minute using the [scroll
lock] key and the four [arrow] keys. See what happens when you
move off the edge of the screen.
Now try the [tab] key. Press [tab] several times. Press [shift
tab] several times. The [scroll lock] does not have an effect
here. It only affects the [arrow] keys.
Next type some text. You may type anywhere you like, including
right over the top of your plot.
If you make a mistake simply press either the [backspace] key or
the [del] key.
If you want to type on the bottom 2 rows, first press F10 to turn
off the DATA row display and then press F7 to turn off the KEY
row display. Both of those keys will toggle their respective
display lines on or off.
Try entering text right over an area of the plot. Now press the
[backspace] or [del] key and see what happens. That part of the
graph is restored! This is why the graph was saved after drawing
it on the screen.
Enter as much text as you like. You can label the axes. Toggle
F10 to see the limits of the axes and the spacing, but watch out.
_
PC-Graph User's Guide Page 15.
It will clear out any typing you've done on that line.
When you're through, press F2.
2.4. SAVING THE PLOT
You save the plot to disk. It's saved exactly as it looks on the
screen -- the cursor temporarily disappears.
Next, the screen goes blank and you are asked to enter a name for
the plot. Type in a name. This name will be the file name on the
disk. Do not enter a period or the three character suffix which
is sometimes used with a file name. PC-Graph automatically
supplies its own file suffix.
After the name is entered, your plot is shown again. If you wish
you may continue labeling and save it again with a different
name, or you may go on to a different option.
2.5. PRINTING
Assuming you have a printer and did not type an "N" when asked to
"indicate printer" at the beginning of this tutorial, let's print
our graph.
Make sure your printer is set to top of form and is on-line.
Press F4.
The printing process will take about 3 minutes. If you want to
cancel the printing process, press any key on the keyboard and
you will return to the mode you came from (At this point in the
tutorial, you would return to Label Mode).
If your printer is off, you'll hear a beep. Turn the printer on
and press F4 again.
If the printer is off-line, just set the printer on-line and the
printing will start.
If you typed an "N" (indicating no printer) way back when you
were asked "indicate printer" then forget it. The print option is
not being supported. You'll hear a beep.
_
Page 16. PC-Graph User's Guide
2.6. LOADING PLOTS FROM DISK
One more thing to try. We are going to load a plot from the
disk. These are plots that have previously been saved (you just
did one).
Press F3. You'll get a list of available plots. The name you
entered will be among them. Simply type the filename you want
(or enough of the name to make it unique) and press [enter].
The graph will be drawn on the screen and will be saved in a
temporary file on the disk (as before, for labeling purposes).
Notice that F5 is not an option this time. This is because
PC-Graph did not read the actual data. Therefore, it could not
plot the file. It could only restore a saved image. You may
still label and print it, and even save it under a new name.
There are several plots that have been saved to the disk for you
to examine. Look at them so you can get an idea of what you can
do with PC-Graph.
When you want to exit the program, go back to the Main Menu (F9)
and press the [Esc] key.
For a more detailed explanation of how each of the options and
its features works, refer to the applicable section.
2.7. COMMENT
We did not show everything in this tutorial nor did we intend to.
You'll get a fuller understanding of what can be done by reading
the rest of this manual and experimenting with files. Most users
have found PC-Graph easy to use.
_
3. REFERENCE SECTION
3.1. STARTING THE PROGRAM
To start the program, put the PC-Graph diskette in your default
drive (usually the "A" drive) and type "pc-graph" (without
quotes).
When prompted with the question "Which drive has the data to be
graphed [A-H]", enter the letter corresponding to the disk drive
where your database, report or plot files will be stored.
The drive that will have those files may also be the default
drive. If this is the case, you may now remove the PC-Graph
diskette (it's not used after the program is loaded) and put your
data diskette in it's place.
PC-Graph now needs to know about your printer. Two printers are
currently supported: the IBM graphics printer and the Epson MX-80
with Graftrax. If you have the IBM, then enter an "I" (uppercase
or lower -- no quotes) and if you have the Epson, enter an "E".
If you do not have either of these then enter "N".
3.2. MAIN MENU
The PC-Graph menu looks like this:
_______________________________________________________________
PC-GRAPH MENU
'ESC' to exit
F1 - Plot data F2 - Save plot to disk
F3 - Load plot from disk F4 - Print screen
F5 - View menu F6 - Label plot
F7 - Turn key row on/off
F9 - Main menu (here)
1-Plot 3-Load 7-Kyoff
_
Page 18. PC-Graph User's Guide
_______________________________________________________________
This is what appears on your screen after the introductory
prompts. This is the list of options you may execute while
running PC-Graph. You move from one option to another by using
the function keys (F1 - F10).
However, most of the functions are not "active" all the time.
There are times when certain functions would not make any sense,
depending on what you are doing. For instance if you are at the
main menu, it would not make any sense to try to "Save plot to
disk" (F2), because there is no plot on the screen, so when you
are at the main menu, "Saving" is not an option.
Look at the bottom row of the main menu screen. It looks like
this:
1-Plot 3-Load 7-Kyoff
This row, which appears at the bottom of your screen, shows you
which options are currently active. The numbers represent
function key numbers and the labels are the options associated
with that function key (they represent the labels in the main
menu).
For example, if you wanted to plot a report or database file you
would press the F1 key. If you wanted to "Load" a previously
saved plot you would press the F3 key.
This row of "active" options will always appear at the bottom of
your screen unless you turn them off.
Now let's find out what each of these options is:

and the different file types that are used with the program.
Your PC-Graph disk comes with the following files:
**************************************
* Omitted from the evaluation copy *
**************************************
The only files you need for this version of PC-Graph are
pc-graph.exe and pctext.bin. They must both reside on the same
diskette and when you run PC-Graph you must be set default to the
drive it resides on.
