I. INTRODUCTION
This program is designed to allow the user to create, display,
and print X/Y, Log, Bar, and Pie graphs, as well as graphs of
functions of a single variable [Y = F(X)], and functions of
two variables [Z = G(X,Y)].
The program implements a "quick-and-dirty" approach to graph
construction, and may lack a few of the niceties that other
professional packages offer. However, the program should be
simple to use, and practically all popular graphics display modes
(CGA through VGA) are supported.
II. SETTING UP
To start the program, type "zgraf" (see command-line switch options,
next section). A menu should appear on the screen. Before using
the program, you may want to adjust the screen/menu colors to your
liking, and you may want to specify the system's graphics
capabilities (i.e., the graphics mode and resolution that you plan
to use for displaying graphs). To do this, go to the "Options" menu
heading, at the top, far right of the screen.
Menu and Screen colors may be changed by selecting "Menu/screen
colors" and then pressing the desired key (A-L) to change the color
of the desired section of the menu screen. By repeatedly cycling
through color combinations, it should be possible to arrive at a
satisfactory set of colors for screen display on any type of monitor
[Note that the colors selected here apply only to immediate screen
colors, and not to graph colors. Graph colors may be set at the
time of graph construction. Alernatively, graph colors and settings
may be set using the "Graph default params." sub-menu. Some
experimentation may be required in order to determine appropriate
values for each of the graph color settings, so you may want to
postpone choosing default graph colors until you have tried making a
few graphs...]
Specifying your system's graphics capability requires that you make
appropriate selections under both the "Driver type" and the
"Video mode/resolution" sub-menus (which are also both under the
main "Options" menu heading). These menus should be self-
explanatory. If, for example, you plan to use a Color Graphics
Adapter to display graphs in 640 x 200 resolution, you would select
"CGA" under the "Driver type" sub-menu, and "CGAHI (640 x 200)"
under the "Video mode/resolution" sub-menu.
Once you have selected suitable Screen Colors, Graph Colors, and an
appropriate graphics driver and mode/resolution combination, you
may save these settings by selecting the "Save Configuration" option.
If this is done, the next time the program is run, the menu will
appear in previously selected screen colors, and the graphs will be
constructed using previously specified colors and graphics settings.
Note that you are not limited to using a single graphics driver/
mode/res. combination. It is possible to "override" the "default"
settings to create graphs in a new mode/resolution, at any time.
For instance, if you have an EGA system and have selected the default
"CGA" and "CGAHI" settings as given in the example above, you can
first view a graph in this "CGA" mode, and then select new "EGA"
settings for the graphics mode/res. and driver--and immediately re-
view the same graph in an "EGA" mode. Further, if you select
"AUTODETECT" under the "Driver type" Menu, the system will
automatically select the "highest" graphics display mode/driver
available for use on your system. . .
III. COMMAND-LINE SWITCH OPTIONS
The following switches may be specified on the command-line:
/ROM -- (ROM-BIOS video) The default pgm. operating
mode is to use direct hardware video writes; if your
system will not support "direct-video" access, but is
"ROM-BIOS" compatible, use this switch--i.e., type
"zgraf /ROM" at the command-line to run the program.
The program will still run, albeit somewhat slower.
(the "/ROM" switch may also be used for "demo.exe").
IV. CONSTRUCTING GRAPHS
Instead of giving detailed directions for constructing individual
graphs, a brief description of each type of graph is given, and
an example of constructing a graph of each category is demonstrated.
The directions should become fairly intuitive after working through
just the few examples listed here. . .
A. F(X) Graph
Description: Graphs a function F(X), for X in the range
(initial value, final value), using a specified
number of intermediate data points [n], where
3 <= [n] <= 200.
Notes: For most graphs, choosing a value of [n] between
75 and 100 provides adequate "resolution"; larger
values of [n] require longer graph calculation
times. Automatic graph scaling is performed
to correspond with the minimum and maximum y-
values over the range (xmin,xmax).
Up to 130 characters may be entered for the
function F(X). The function is evaluated in
double-precision format. Most standard math
functions are allowed; see Section VI, below,
for a complete list of legal functions.
Example: Graph F(X) = sin(X)/X, for X >= -20 and
X <= 20, using [n] = 75 data points.
1. Select "Enter function F(X)", and
type in "sin(X)/X". Notice that
a capital "X" is used for the variable.
2. Select "Initial X-value", and enter
"-20.0". Notice that a floating-pt.
value was entered.
3. Select "Final X-value", and enter
"20.0". Again, notice that a floating-pt.
number was entered.
4. Select "Number of data points", and enter
"75". This corresponds to the number of
intermediate function evaluations to be
carried out by the program within the interval
(-20,20).
5. Select "Title", and enter "Graph of sin(X)/X"
as the Main Title. .
6. Select "Generate graph". After a second or
two of calculation time, the graph should
appear on the screen...
Note: Now, to experiment (or to make things
look better if the graph is now
displayed in colors that are difficult
to see) try entering variou s numbers
under the "Axis color", "Plot color",
and "Background color" categories, and
selecting "Generate graph" again to
re-view the graph. The "Screen grid
toggle" can be used to switch a grid
of dots for the graph on or off. You
can continue trying different settings
and re-generating the graph as many
times as necessary to obtain a pleasing
display. Once suitable settings for
Axis, Plot, and Background colors
are found, you can save these values
as default colors, using the "Options"
menu, "Graph default params." sub-
heading.
B. G(X,Y) Graph
Description: Graphs a function Z = G(X,Y), for X, Y, and Z in
the range (Xmin, Xmax), (Ymin, Ymax), and
(Zmin, Zmax), respectively.
Notes: Since no automatic scaling is performed, values
for the min and max values should be selected
to "include" the range of values which will
be generated. For example, if your function
is G(X,Y) = sin( 0.05 * sqrt(X*X + Y*Y) ), with
-100.0 <= X <= 100.0, and -100.0 <= Y <= 100.0
(as in the example below), one could select the
values (Zmin, Zmax) as (-1.0, 1.0), so that all
points of the sine-function will be included
and displayed.
Again, up to 130 characters may be entered for
the function G(X,Y). The function is evaluated
in double-precision format; see list of math-
functions that are supported in Sect. VI, below.
Since G(X,Y) "surface plots" require many lines
to be drawn, it may take a minute or two for the
program to draw a complete graph--please be
patient. You can abort the graph construction
process at any time while the graph is being
created by pressing [Esc]--this may save you some
time if you do make a mistake...
Example: Graph G(X,Y) = sin( 0.05* sqrt(X*X + Y*Y) ),
for X in the range (-100,100), and Y in the range
(-100,100).
1. Select "Enter function G(X,Y)", and
type in "sin( 0.05 * sqrt(X*X + Y*Y) ).
2. Select "Data variable ranges", then
under the sub-menu enter the values
-100.0 for Xmin, 100.0 for Xmax, -100.0 for
Ymin, and 100.0 for Ymax, respectively.
Notice that floating-point values are used.
3. Enter -1.0 and 1.0 for Zmin and Zmax,
respectively. Press [Esc] to return to
main G(X,Y) menu.
4. Select "Title", and enter "Surface Plot of
a Sinusoid" as the main title.
5. Select "Generate G(X,Y) graph" to create
the graph (when completed, this graph
should look like a hat (or a "bundt-cake
pan").
Again, you can try entering various numbers
under the "Axis color", "Plot color", and
"Background color" categories, and then re-
draw the graph. The "Screen Frame Toggle"
can be used to switch the "wire-frame" outline
for the graph on or off.
Note: For the current version of the program,
the "wire-frame" grid is drawn only in
the (320 x 320) and (640 x 200) video
modes (CGA through VGA); also the
"hidden-line" removal algorithm seems
to work best in these modes. For the
nicest-looking graph, it is recommended
that you do not exceed (640 x 200) res-
olution for this particular graph--but
the plot is drawn (without the "wire-
frame") in all video modes if you're
absolutely bound and determined. . .
C. Discrete X/Y Graph
Description: Graphs up to 200 (x,y) data-points (total) taken
from a data-file, displaying a user-defined symbol
at each data point. By using different symbols,
multiple "groups" of data may be displayed on a
single X/Y graph grid.
Notes: Each (x,y) coordinate must be entered on its own
line in the data-file, in floating-pt. format
(anywhere on the line, but with at least one
space separating the x- and y-coordinates). The
symbol to be displayed must be a single character,
and must follow the y-coordinate anywhere on the
line. Each "group" of data should have a unique
symbol associated with it.
If connecting lines are to be drawn between
adjacent data-points (connecting lines can be
added/removed by the "Connecting-line toggle" menu
selection), it is important to list the data-
points in the file sequentially--in the order
the data is to be plotted, as in the example
below. . .
Example: It is desired to display two groups of (x,y)
data on a graph, and to plot the first group
of data using plus-sign (+) symbols, and the
second group using "oh" (o) symbols.
The first group of data is: (0,10), (2.5,10),
(5,10), (7.5,10), (10,10), (12.5,7.5), (15,5),
(17.5,2.5), (20,0), (22.5,2.5), (25,5),
(27.5,7.5), (30,10), (32.5,10), (35,10),
(37.5,10), and (40,10).
The second group is: (0,20), (2.5,25), (5,30),
(7.5,35), (10,40), (12.5,35), (15,30), (17.5,25),
(20,20), (22.5,25), (25,30), (27.5,35), (30,40),
(32.5,35), (35,30), (37.5,25), and (40,20).
1. Create the data-file. Use an editor to edit
a file "xy.dat", so that it looks like this
(notice that floating-pt. values are used
throughout):
This is the first line of file -> 0.0 10.0 +
2.5 10.0 +
5.0 10.0 +
7.5 10.0 +
10.0 10.0 +
12.5 7.5 +
15.0 5.0 +
17.5 2.5 +
This is the first -> 20.0 0.0 +
group of data-points, which -> 22.5 2.5 +
will be displayed using -> 25.0 5.0 +
plus-signs (+) -> 27.5 7.5 +
30.0 10.0 +
32.5 10.0 +
35.0 10.0 +
37.5 10.0 +
40.0 10.0 +
Blank line(s) to separate
data-groups (ignored by pgm.) ->
0.0 20.0 o
2.5 25.0 o
5.0 30.0 o
7.5 35.0 o
10.0 40.0 o
This is the second group -> 12.5 35.0 o
of data-points, which will -> 15.0 30.0 o
be displayed using oh's (o) -> 17.5 25.0 o
20.0 20.0 o
22.5 25.0 o
25.0 30.0 o
27.5 35.0 o
30.0 40.0 o
32.5 35.0 o
35.0 30.0 o
37.5 25.0 o
This is the last line of file -> 40.0 20.0 o
When done editing, save the file, and
run the "zgraf" program.
2. Under the "Discrete X/Y" top heading, select
"Load data file". When prompted for the
name of the data-file, type "xy.dat". The
program should indicate that 34 data-points
were "loaded".
3. Select "Generate graph" to draw the graph.
Again, you may want to enter a title, and
experiment with Axis/Plot/Background color
options to obtain a more pleasing graph...
D. Log Graphs
Description: Graphs up to 200 (x,y) data-points (total) taken
from a data-file, in a similar format to that
used in the Discrete X/Y graphs discussed earlier,
but on a logarithmic-type grid.
Notes: (See Discrete X/Y Graph for description of
data-file formats).
Three types of logarithmic graphs can be
constructed:
(1) Linear X, Log Y
(2) Linear Y, Log X
(3) Log X, Log Y
For the log scales, it is required that:
(1) All data coordinates be > 0.0.
(2) The ratio of largest to smallest
coordinates in the graph must
not exceed 100,000.
Example: Given the data-points:
(1.0, 1.0),
(2.0, 100.0),
(3.0, 1000.0),
(4.0, 1000000.0)
one could create a log-log graph
using only the first 3 data-
points, because if the 4th data-
point were included, the y-
coordinate ratio would be:
10^6 / 1.0 = 10^6,
which exceeds the maximum
allowable ratio (10^5).
Example: Display two groups of data on a log-log graph,
and plot the first group of data using plus-sign
(+) symbols, and the second group using "oh" (o)
symbols.
The first group of data is: (1,8), (10,80),
(100,800), and (1000,8000).
The second group is: (50,50), (500,500),
(5000,5000), and (50000,50000).
1. Create the data-file. Use an editor to edit
a file "log.dat", so that it looks like this
(notice that floating-pt. values are used
throughout):
1.0 8.0 +
10.0 80.0 +
100.0 800.0 +
1000.0 8000.0 +
50.0 50.0 o
500.0 500.0 o
5000.0 5000.0 o
50000.0 50000.0 o
When done editing, save the file, and
run the "zgraf" program.
2. Under the "Log Graph" top heading, select
"Load data file". When prompted for the
name of the data-file, type "log.dat". The
program should indicate that 8 data-points
were "loaded".
3. Under the "Format of log graph" item,
select "3" for Log-Log graph
4. Select "Generate graph" to draw the graph.
Again, you may want to enter a title, and
experiment with Axis/Plot/Background color
options to obtain a more pleasing graph...
E. Bar Graphs
Description: Allows the user to make a bar graph, of up to
3 sets of bars.
Notes: The maximum number of bars in the graph must
not exceed 30. The number of bars is calculated
from the formula:
(# Bars, Total) = (# Bars/Set) * (# Sets).
As an example, the program could handle 3 sets
of bars, 10 bars/set (30 bars total), but not 2
sets of bars, 16 bars/set (32 bars total).
Graph Options: 2-D or 3-D bars can be drawn;
fill-color and pattern can be
selected.
Example: Create a 3-D Bargraph entitled "Average Rainfall
(in.), Jan-May", for 3 cities as follows:
Chicago:
Jan.: 18, Feb.: 22, Mar.: 30, Apr: 40, May: 35.
New York:
Jan.: 22, Feb.: 33, Mar.: 20, Apr: 11, May: 20.
Seattle:
Jan.: 58, Feb.: 72, Mar.: 40, Apr: 35, May: 25.
1. Select "Number of bar groups", and enter
"3"; select "Bars/group" and enter "5".
2. Select "Enter data" and enter the fifteen
quantities in floating-pt. format, i.e.,
"18.0 [Enter] 22.0 [Enter] 30.0 [Enter]
40.0 [Enter] 35.0 [Enter] 22.0 [Enter]
33.0 [Enter] 20.0 [Enter] 11.0 [Enter]
20.0 [Enter] 58.0 [Enter] 72.0 [Enter]
40.0 [Enter] 35.0 [Enter], and 25.0 [Enter].
3. Select "Item titles" and enter the five
bar-titles, i.e., "Jan. [Enter] Feb. [Enter]
Mar. [Enter] Apr. [Enter] May [Enter]".
4. Select "Legend titles", and type in "Chicago",
"New York", and "Seattle".
5. Select "Title", then "Main Title", then enter
"Average Rainfall (in.), Jan-May".
6. Select "3-D Bars".
7. Select "Generate bargraph" to draw the graph.
8. To experiment, you may want to try selecting
different bar colors and bar fill-patterns,
and re-generating the graph.
F. Pie Graphs
Description: Allows the user to make a pie graph.
Notes: Max. Number of Slices in Pie: 10.
Options: Single- or Multi-color pies can
be drawn.
Example: Create a Multi-colored Pie Graph entitled
"Grain Sales, by Percent" with the following
data: Wheat: 30, Corn: 25, Soybeans: 20,
Rice: 10, Other.: 15.
1. Select "Number of slices" and enter "5".
2 Select "Enter data" and enter the five
percentages in floating-pt. format, i.e.,
"30.0 [Enter] 25.0 [Enter] 20.0 [Enter]
10.0 [Enter] 15.0 [Enter]".
3. Select "Multi-color pie" (Pie will be
displayed in different colors if the
current graphics driver type & mode/res.
settings support multiple colors).
4. Select "Title" and enter "Grain Sales by
Percent" as the main title.
5. Select "Item titles" and enter the five
item-descriptions, i.e., "Wheat [Enter]
Corn [Enter] Soybeans [Enter] Rice [Enter]
Other [Enter]".
6. Select "Generate piegraph" to construct the
graph.
Notes: Aspect Ratio Adjustment
Some monitors may display an "oblong" or
not-quite-round-looking pie in some
graphics modes; you can make the pie look
more "round" by adjusting the Aspect ratio
(the height to width ratio) of displayed
pixels on the screen. In this program,
the aspect ratio may be set to any
(floating-pt.) value between 0.1 and 10.0,
where smaller numbers tend to expand the
pie in the up-and-down direction, and
larger numbers expand it in a side-to-side
direction. If a value outside the
(0.1,10.0) range (e.g., 0.0) is chosen,
the program will try to automatically
determine an appropriate aspect ratio.
The automatic aspect-ratio selection
(i.e., using 0.0 for the aspect ratio)
often (but not always) produces a nice,
round pie. Some experimentation may be
required to obtain an ideal setting in
your environment...
V. PRINTING GRAPHS
If you have a dot-matrix or equivalent printer, graphs may be
printed by pressing [Prt Sc] when a graph is displayed on-screen.
Using this "print-screen" command requires that you run the DOS
"graphics.com" program prior to running the "ZGRAF" program.
If you are unfamiliar with "graphics.com", please refer to your
DOS manual; the following example may also help. . .
Example: Create and Print a Bar Graph
(1) From the DOS command line, type "GRAPHICS" [Enter]
(Here we'll use the default "graphics.com" settings;
you'll need to specify the full pathname if
"graphics.com" is in another directory, e.g.,
"C:\DOS\GRAPHICS").
(2) From DOS, type "ZGRAF" [Enter], and create the bar
graph given in Sect. IV, part E.
(3) When the graph is displayed on-screen, press
[Prt Sc] to print the graph.
Note: Only screens in the modes supported by "graphics.com" can be
printed [i.e., only screens in the 320 x 200 and 640 x 200 (CGA)
modes are printable under MS-DOS versions 3.X and lower].
VI. MISCELLANEOUS
A. Math Functions
The following are legal math functions for this program:
ABS() -- absolute value
ACOS() -- arc cosine
ASIN() -- arc sine
ATAN() -- arc tangent
COSH() -- hyperbolic cosine
COS() -- cosine
EXP() -- e (= 2.7182) raised to the () power
LOG10() -- common logarithm (base 10)
LOG() -- natral logarithm (base e)
POW10() -- ten raised to the () power
SINH() -- hyperbolic sine
SIN() -- sine
SQRT() -- square root
SQR() -- square, i.e., () raised to 2nd power
TANH() -- hyperbolic tangent
TAN() -- tangent
These functions may be used in either the F(X) and G(X,Y)
expressions, or with the Desktop Calculator (described below) to
represent the standard mathematical functions, in double
precision.
B. Calculator Mode
Algebraic expressions may be evaluated using the built-in
calculator, under the "Options" menu (can also be accessed
with the [Alt C] hotkey). All math-functions listed above
are supported. Up to 65 characters per line are allowed.
To exit the calculator mode and return to the main menu,
press [Esc].
Example: Calculate exp( sin(2.0) ).
1. Select "Calculator" under the "Options" menu.
Under "Expression:" type in "exp(sin(2.0))",
and press [Enter].
2. The answer, 2.482578, should appear below the
"Result:" line.
C. Saving/Restoring Graphics Images
If you have a graph displayed on-screen that you would like
to "capture" and save in a file for later recall and review,
here's how to do it:
(1) Specify the file name that you wish to save
the graphics image in--you can either select
"Options", "Image load/save", then "Graphics
Image File Name", or just use the [Ctrl I]
hotkey to bring up the same prompt. If no name
is specified, the image file name will default
to "ZGRAF.GRF".
(2) Create the graph you wish to save (see Section
IV, Graph Construction for instructions, if
necessary). When the graph is displayed to your
liking, press [Ctrl S] to save the image. If
sound is enabled, you should hear a tone, and
when the disk I/O activity completes, a message
should inform you that the graphics image was
saved. . .
(3) To restore this image (or any image saved to a
file), just specify the file name of the image
file you wish to restore, as in (1) above (if
the current image file name is not already
correct), then select "Options", "Image load/
save", and "Restore Graphics Image". Altern-
atively, you may use the hotkey [Ctrl R] to
accomplish the same function. The stored
image should be redrawn on the screen. . .
My apologies for the extremely slow speed of the graphics
save/restore operations. A more efficient, hi-speed
algorithm is being sought, and should be available in future
versions of this program...
