I. ZGRAFWIN -- AN INTRODUCTION

This program is designed to allow the user to create, display, and

print X/Y, Polar, Log, Bar, Pie, and Area graphs, as well as graphs

of 2-D functions/expressions [Y = F(X), or F(X,Y) = 0], and 3-D

functions [Z = G(X, Y)] in the MS-Windows 3.X environment.

The program implements a "quick-and-dirty" approach; it may lack a

few of the fancy features that other professional packages offer,

but it does allow the user to create, display, and print a number

of popular graph styles within Windows. It also allows the

importing and exporting of graphics images in color PCX format.

If you are familiar with the DOS ZGRAF program, you will find this

program very similar in operation, and will probably not need to

read this document, other than just to get started. Otherwise, if

you're new to ZGRAF/ZGRAFWIN, you may want to run the demo

program, to get a quick overview of some of the graph styles

available.

ZGRAFWIN is a shareware program. You are encouraged to try it out

and pass it around to your friends. If you decide to use it,

please register the software. The registration fee is just $15.

Requirements for ZGRAFWIN are: MS-Windows ver. 3.0 or later. A

color VGA monitor and a mouse are strongly recommended.

II. SETTING UP

To start the program, run "ZGRAFWIN.EXE" from the Windows Program

Manager.

III. COMMAND-LINE SWITCH OPTIONS

None.

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. . .

By the way, if you need help while working with ZGRAFWIN, just

press [F1] or select the "Help" top-level pull-down menu. Help is

available on a number of topics--like information on the different

graph styles available, instructions on how to print a graph, and

more.

-------------------------------------------------------------------------------

A. F-2D Graph

Description: Graphs up to four separate "2-dimensional"

expressions in the x-y plane. The user may graph

both functions [i.e., equations of the form F(X) =

0], and non-functions [equations of the form F(X,Y)

= 0]. Data ranges may be selected for graphs

either automatically [auto-scaling ON], or manually

[manual-scaling]; in the latter case the graph

is shown over the range:

xmin <= X <= xmax and ymin <= Y <= ymax,

where the user selects the min. and max. values.

Notes:The first form [F(X) = 0] requires a true function,

e.g., F(X) = 5.0 * X + 3.0 or F(X) = sin(X). The

second form [F(X,Y) = 0] may be used to graph

"non-functions" in the x-y plane, like circles,

hyperbola, etc. For example, one would use an

equation like F(X,Y) = X*X + Y*Y - 25.0 to graph a

circle.

In each case, the user may specify the number of

intermediate data points [n] used to calculate

function values, where 3 <= [n] <= 250. For most

graphs, choosing a value of [n] between 75 and 100

provides adequate "resolution"; larger values of

[n] produce a nicer-looking graph, but will take

longer to calculate. The complexity of the

function also impacts the calculation time. On

most machines, it shouldn't take but a few seconds

to generate a F(X) graph, or a minute or two for an

F(X,Y) graph, with n = 100.

Up to 130 characters may be entered for the F-2D

expression, and the function/expression is

evaluated in double-precision. Most standard math

functions are allowed; see Sect. VI, Paragraph A

for a complete list of legal functions, and for

information on legal function syntax.

Example #1: Graph the following four equations on a single graph

over the range -20 <= X <= 20, -2 <= Y <= 5, using n =

100 intermediate data-points to evaluate each function:

F(X) = sin(X) / X

F(X) = 2.0 * sin(X) / X

F(X) = 4.0 * sin(X) / X

F(X) = 5.0 * sin(X) / X

1. There are 4 expressions. Select "Setup | Number of

expressions" and select "Four". Select "Setup |

Enter expression(s)", and type: "sin(X)/X",

"2.0*sin(X)/ X", "4.0*sin(X)/X", and "5.0*sin(X)/X"

-------------------------------------------------------------------------------

for the four entries (We use an upper- or

lower-case "X" as the variable).

2. Select "Setup | Data ranges/scaling", then select

"X-minimum" and type "-20.0". Select "X-maximum"

and type "20.0". Notice floating-pt. numbers are

used. Enter "-2.0" and "5.0" for the minimum and

maximum Y-values, respectively. Toggle the

manual-scaling ON (since we are MANUALLY selecting

the data-ranges).

3. Select "Setup | Number of data pts", and enter "100".

This corresponds to the number of intermediate

function evaluations to be used by the program

within the interval (Xmin, Xmax) = (-20, 20).

4. Select "Title", and enter "Graphs of sin(X)/X" as

the Main Title.

5. Select "Draw". After a few seconds, the graph

should appear on the screen...

After the graph is displayed, you can try using various

colors for the "Axis color", "Plot color(s)", and

"Background color" categories. Then select "Draw" to

re-view the graph. You can continue trying different

settings and re-generating the graph as necessary to

obtain a pleasing display.

The "Options | Screen grid toggle" option allows you to

switch a grid of dots for the graph on or off.

Example #2: We'll now try an expression in X and Y. We'll graph

the equation:

1.5 1.5

|X| + |Y| = 25, -10 <= X <= 10, -10 <= Y <= 10

1. To graph an expression like this, first rewrite it

in a form ZGRAFWIN can handle, i.e., in the form

"F(X,Y) = 0". Here, we rewrite the equation as:

(abs(X)) ^ 1.5 + (abs(Y)) ^ 1.5 - 25.0 = 0.0

2. There is only one expression in this case, so

click "Setup | number of expressions" and enter "1".

Select "Setup | Enter expression(s)" and type in the

formula: "(abs(X)) ^ 1.5 + (abs(Y)) ^ 1.5 - 25.0".

3. Select "Data ranges/scaling", and enter "-10.0" for

X-minimum and Y-minimum. Enter "10.0" for X-maximum

and Y-maximum. Turn Manual-scaling ON.

4. Select "Number of data points", and enter "50".

-------------------------------------------------------------------------------

5.Select "Draw". While the graph is calculating, the

approximate amount completed is displayed as a

percentage. After a minute or two of calculation

time, the graph should appear on the screen.

Example #3: Graph the equations of a hyperbola,

2 2

X - Y = 25, and of an ellipse,

2 2

(X/5) + (Y/3) = 1.

1. Select "number of expressions" and enter "2".

select "Enter expression(s)" and type in: "X*X - Y*Y

-25.0" and "SQR(X/5.0) + SQR(Y/3.0) - 1.0".

2. Repeat steps 3-5 of Example #2.

Interrupting

Calculations:For the F-2D graph, it is possible to interrupt the

calculation process by pressing/holding down the

[Esc] key while the graph is being computed, if

desired...

ZOOM Adjust:The "View | ZOOM" feature allows the user to "zoom"

into a particular area of the graph. The user may

select a rectangular region onscreen with the

mouse, and the graph is then adjusted to show the

new region more precisely.

Scroll-Bars:The Up-, down-, left-, and right- arrows on the

scroll- bars may be used to adjust the relative

positioning of the graph (Note: Both the ZOOM and

the scroll-bar action is also available on the X/Y-

Line graph, described later).

Rapid-Color

Adjustment:In ZGRAFWIN when a graph is displayed onscreen, the

left and right arrows increment and decrement the

crurrent background color, respectively. The up-

and down-arrows are used to select and change the

color of items appearing in the foreground,

respectively. In Example 3 above, there were 3

foreground items--the x-y axis, and the 2 graph

traces themselves.

I suggest you use the up- and down-arrows as

follows: First press the up-arrow as many times as

necessary until the foreground item you want to

modify is selected. Then press the down-arrow to

switch between available foreground colors for this

particular item (This rapid-color adjustment is

nice to use with the bar-, pie-, and area-graphs,

as you'll see later).

-------------------------------------------------------------------------------

B. G-3D Graph

Description: Graphs a 3-D function Z = G(X,Y), for X, Y, and Z

in the range (Xmin, Xmax), (Ymin, Ymax), and (Zmin,

Zmax), respectively.

Notes: Despite its appearance on the menu, no automatic

scaling is available for this graph. The user

should select values for the min and max values

that "include" the range of values which will be

generated. For example, if the function is:

G(X,Y) = cos( 0.05 * X *Y ),

with -10.0 <= X <= 10.0, and -10.0 <= Y <= 10.0

(as in the example below), one could select the

values (Zmin, Zmax) as (-1.0, 1.0), so that all

points of the cosine-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 notes on

math-functions and ZGRAFWIN function syntax in

Sect. VI, part A, below.

Interrupting Calc's: Since G(X,Y) "surface plots" require many lines to

be drawn, it may take a little while 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 the [Esc] key -- this may

save you some time if you do make a mistake...

Speed vs. Accuracy: Naturally, there is a tradeoff between graph

accuracy and graph calculation time for this type

of graph, and three accuracy/speed settings may be

chosen. For the first pass at a new function

you might want to use the "Low accuracy / fast"

draw option (under "Setup| Format of graph/speed")

to create a "rough draft", and then for the final

product select the "High accuracy / slow" setting

to generate a more "presentation-quality" graph.

As you might expect, the higher accuracy graph

looks a lot better, but comes at considerable

expense of CPU time--it may take 5-10 minutes

to generate a hi-accuracy graph on a slower

machine...

Example: Graph the function G(X,Y) = cos( 0.05 * X*Y ), for

X in the range (-100,100), and Y in the range

(-100,100). Use medium accuracy/speed.

1. Select "Setup | Enter 3D function", and type

"cos( 0.05 * X * Y ).

-------------------------------------------------------------------------------

2. Select "Setup | Data ranges", then manually

enter the values -10.0 for X-minimum, 10.0

10.0 for X-maximum, -10.0 for Y-min., and 10.0

for Y-max., respectively.

3. Enter -1.0 and 1.0 for Z-min. and Z-max.,

respectively.

4. Select "Setup | Format of graph/speed", then

"Medium accuracy / medium".

5. Use Windows to "Maximize" the screen window in

which ZGRAFWIN is running to full-screen (this

isn't necessary, but seems to help the

hidden-line removal algorithm for this graph

work a little better).

6. Select "Draw" to create the graph.

Wire Frame Toggle: "Options | Screen Frame Toggle" may be used to

switch the "wire-frame" outline for the graph on

or off.

Band-Colorization: A "band colorization" feature allows you to iden-

tify six distinct z-value regions in the graph by

color. This feature can be toggled on/off (see

"Band colorization toggle" under "Format of graph/

speed"). The color of each band corresponds to

each plot color, which you can select with the

"Plot color(s)" selection.

Sample Functions: If you'd like to look at some other "easy"

3-D functions, here's some to try:

sin( 0.05 * X * Y ) , -10 <= X <= 10

-10 <= Y <= 10

-1 <= Z <= 1

cos( 0.5*X ) - sin( 0.5*Y ) , -10 <= X <= 10

-10 <= Y <= 10

-2 <= Z <= 2

sin( 0.05 * sqrt(X*X + Y*Y) ),

-100 <= X <= 100

-100 <= Y <= 100

-1 <= Z <= 1

-------------------------------------------------------------------------------

C. X/Y Line Graph

Description: Graphs up to 1000 (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 you want lines drawn between data-points

(connecting lines may be added/removed by the

"Connecting-line toggle" option selection), it is

important to list the data-points in the file

sequentially--in the order in which the data is to

be plotted, as in the example below. . .

Example: It is desired to display five groups of (x,y) data

on a graph, and identify the individual groups

with the symbols "A", "B", "C", "D", and "E".

The first data group is: (0, 10), (1, 0), (2, 30),

(3, 20), (4, 10), and (5, 20).

The second data group is: (0,50), (1,60), (2,65),

(3, 65), (4, 60), and (5, 50).

The third data group is: (0,90), (1,100), (2,80),

(3, 90), (4, 100), and (5, 90).

The fourth data group is: (0, 110), (1, 120),

(2, 130), (3, 120), (4, 125), and (5, 115).

The fifth data group is: (0, 150), (1,145),

(2, 155), (3, 160), (4, 150), and (5, 135).

1. Create the data-file. Use an ASCII editor

(you can use ZGRAFWIN's built-in editor if you

like--see section VI, part B) to create a file

called "xy.dat". For convenience this file is

included with ZGRAFWIN [the "xy.dat" file has

some additional instructions in it, which you

may ignore for now, with the exception of the

"#GRAPH_TYPE" line, and some options in the

"OPTIONS" section, as will be explained]. The

data file looks like this:

This tells ZGRAFWIN the -> #GRAPH_TYPE = XY_GRAPH

type of graph to construct.

-------------------------------------------------------------------------------

These lines specify some -> #OPTIONS = GRID ^ CONNECT ^

of the different available MANUAL ^ SYMBOLS ^

graph options. The graph -> #XMIN = -1.0

has a background grid -> #XMAX = 6.0

("GRID") with connecting -> #YMIN = -20.0

lines between data points -> #YMAX = 170.0

("CONNECT"), and manual

graph scaling will be used

("MANUAL"). The graph symbols will be displayed ("SYMBOLS").

The "XMIN", "XMAX", "YMIN", and "YMAX" variables correspond to the

min. and max. values used on the X- and Y- axes on the graph. If

the XMIN, XMAX, YMIN, and YMAX values were not listed, or if the

"AUTO" (automatic scaling) option was listed instead of "MANUAL"

(manual scaling), the XMIN, XMAX, YMIN, and YMAX values would be

automatically determined by the program, based upon the X- and Y-

input-data ranges occurring in the data.

0.0 10.0 A

1.0 0.0 A

This is the first group of 2.0 30.0 A

data-points, which will be -> 3.0 20.0 A

displayed with 'A' symbols. 4.0 10.0 A

5.0 20.0 A

Blank lines or lines with a

"!" in the first column are ->

comment lines, and are

ignored by ZGRAFWIN.

0.0 50.0 B

Second group of data-points 1.0 60.0 B

will be displayed using 'B' -> 2.0 65.0 B

symbols. 3.0 65.0 B

4.0 60.0 B

5.0 50.0 B

More Blank lines (ignored) ->

(2 More Groups of Data Go

Here, And Are Displayed

Using 'C' And 'D' Symbols. ->

The data is not repeated

here, for reasons of space).

0.0 150.0 E

Fifth group of data-points 1.0 145.0 E

will be displayed using 'E' -> 2.0 155.0 E

symbols. 3.0 160.0 E

4.0 150.0 E

Last line of file -> 5.0 135.0 E

When done editing, save the file, and return

to the ZGRAFWIN "X/Y Line" menu.

2. Under the "X/Y Line" Setup menu, select "Load

data file". When prompted for the name of the

data-file, type "xy.dat". The program should

indicate that 30 data-points were "Loaded OK".

3. Select "Draw" to draw the graph.

-------------------------------------------------------------------------------

D. Polar Graph

Description: Graphs up to 1000 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 polar graph grid. Input

data may be in either RECTANGULAR (x,y) format

or in POLAR (radius, angle) format.

Notes: (Same as for X/Y Line Graph)

Example: Graph the 22 data points listed in the file

"polar.dat", included with ZGRAFWIN. Since

data in this file is in polar format, each

line of data in the file is of the form:

[r] [theta] [symbol] ,

where [r] and [theta] are the standard polar

radius and angle (radians) quantities, and

[symbol] is the symbol to be displayed (="*").

1. Use the ZGRAFWIN editor to look at the

"polar.dat" file (select "Editor" under

the "Options" menu to bring up the editor,

then "Open" to Open a File, and type in

"polar.dat"). The lines beginning with

"#" are command-lines and provide specific

graph information to ZGRAFWIN. For

example, there are commands to specify the

background, axis, and plot colors for the

graph.

There is also an "#OPTIONS" line. We use

this command (as you may have observed) to

specify any of several options for the

graph. Here, to inform ZGRAFWIN that data

for this graph is being entered in POLAR

[not (x,y) RECTANGULAR] format, the

"POLAR" switch is specified on the

"#OPTIONS" line.

The last part of the file is just a list

of 22 data points.

2. When finished examining the file, select

"Setup | Load data file". When prompted

for the name of the data-file, type in

"polar.dat". ZGRAFWIN should indicate

that 22 data-points were "Loaded OK".

3. Select "Draw" to draw the graph.

-------------------------------------------------------------------------------

E. Log Graph

Description: Graphs up to 1000 (x,y) data-points (total)

taken from a data-file, in a similar format to

that used in the X/Y line graphs discussed

earlier, but on a logarithmic-type grid.

Notes: (See X/Y Line Graph for description of data-

file formats).

Three styles of logarithmic graphs may 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 10^5.

Example: Given the data-points:

(1.0, 1.0),

THIS EXAMPLE WILL NOT WORK ! ->(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;

plot the first group of data using plus (+)

symbols, and the second group using "oh" (o's).

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.First create the data-file. Use an ASCII

editor to edit the file "log.dat", so that

it looks like this (notice that floating-

pt. values are used for the data points):

-------------------------------------------------------------------------------

! ************************

The "!" symbol in the 1st col. -> ! * Sample Log Graph. . .

indicates that these are com- ! ************************

ment lines.

The '#' symbol in 1st column -> #GRAPH_TYPE = LOG

denotes a command line. Here #OPTIONS = LOG_LOG ^ CONNECT ^

ZGRAFWIN is told that this is

a log graph, and we've chosen

the LOG_LOG ( log-X, log-Y )

format. The 2nd option says

that line-connection is turned

on, so that lines are drawn

between data points. Because

there are two options on one

line, each option is separated

with the carat "^" delimiter

(The delimiter's needed when

there are two or more words

or fields to separate).

The title of the graph is also -> #MAIN_TITLE = Sample Log Graph ^

provided. The carat symbol is

used to indicate the end of

the string here also (Since

titles may contain whitespace

between words, a space is not

used as the delimiter).

Next, set the background, -> #BKG_COLOR = 0

axis, and the 2 plot colors to #AXIS_COLOR = 12

(color 0), bright red (color #PLOT_COLORS = 13 ^ 14 ^

12), bright magenta (color

13) and bright yellow (14),

respectively. See Note #2 in

Part VI, Sect. C, "Command

Line Syntax", about Plot

and Fill Colors.

"#DATA" is an optional identi- -> #DATA

fier to indicate that the 1.0 8.0 +

8 data-points now follow. 10.0 80.0 +

100.0 800.0 +

Note: For more details on 1000.0 8000.0 +

the "#" commands and options,

refer to Section VI, Part C. 50.0 50.0 o

500.0 500.0 o

5000.0 5000.0 o

50000.0 50000.0 o

When done editing the data file, return to

the Log Graph menu.

2. Under the "Log Graph" Setup heading, select

"Load data file". Type in "log.dat" as the

name of the file. The program should

indicate 8 data-points were "Loaded OK".

3. Select "Draw" to draw the graph.

-------------------------------------------------------------------------------

F. Bar Graph

Description: Allows the user to make a bar graph, of up to 3

separate groups of bars.

Notes: The total number of bars in the graph must not

exceed 30. The number of bars is calculated

from the formula:

(# Bars, = (# Groups) x (# Samples per Group)

Total )

As an example, the program could handle 3 groups

of bars, with 10 samples in each group (30 bars

total), but not 2 groups of 16 samples each (32

bars total).

[Note: the term "sample" is used here somewhat

loosely; sampling in a statistical sense is not

necessarily implied...]

Options: 2-D or 3-D bars may be drawn; the fill-color

of each bar (group) may be chosen. Data may be

entered in manually as in Example #1 below,

or taken from a data file as in Example #2.

Automatic or manual scaling may be used to

determine the range of bar heights on the y-axis.

Example #1: Create a 3-D Bargraph entitled "Average Rainfall

(in.), Jan-May", for 3 cities, using the follow-

ing rainfall data:

Chicago:

Jan.: 18, Feb.: 25, 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. For this example, there are three groups of

bars (1 bar group for each city), and there

are five samples in each group. Select "Bar

groups" under "Setup", and enter "3"; select

"Number of samples/group" and enter "5".

2. Select "Enter data" and manually enter the

15 rainfall quantities into the first 15

cells on the form entry screen. We enter

the first sample for the first group

(Chicago), then the first sample for the

second group (New York), then the first

sample for the third group (Seattle). Then

we enter the second samples for the first,

second, and third groups, respectively,

-------------------------------------------------------------------------------

etc. [Tab] may be used to move from one

field to the next on this screen. So type

in:

"18.0 [Tab] 22.0 [Tab] 58.0 [Tab]

25.0 [Tab] 33.0 [Tab] 72.0 [Tab]

Then select the "OK" button.

3. Select "Titles | Item titles" and enter the

5 individual sample descriptions, i.e., "Jan.

[Enter] Feb. [Enter] Mar. [Enter] Apr.

[Enter] May [Enter]".

4. Select "Legend titles", and type in the 3

group legend titles, i.e., "Chicago", "New

York", "Seattle".

5. Select "Main Title", then type in "Average

Rainfall (in.), Jan-May".

6. Select "Options | Style", then "3-D Bars".

7. Press "Draw" to draw the graph.

8. To experiment, you may want to try selecting

different bar fill-colors, and re-generating

the graph. By the way, each unique fill-

color corresponds to the color of an indiv-

idual bar group in the set.

Rapid Color Adjust: For Bar Graphs, The up- and down- arrows may be

used to change the fill-color of each group

individually.

Painting in Fills: To Paint in a particular (bounded) region of the

graph, just position the mouse to a location

within the region to colorize, and click the

left button. The region will be filled in with

the current paint color [The paint color may be

set/changed under the "Options", "Colors"

submenu, or by just clicking the right mouse

button]. This is a quick way to color in

regions, and is especially useful on the pie,

bar, and area graphs for coloring in fills.

Example #2: Create the same graph demonstrated above, but

use the input data from the data-file "bar.dat"

[This file contains the same data which was

entered manually in Example #1].

1. Use an editor (e.g., the ZGRAFWIN editor)

to edit the file "bar.dat". We'll examine

in detail the commands present in this file

(listed here for convenience):

-------------------------------------------------------------------------------

Indicate the Type of Graph -> #GRAPH_TYPE = BAR_GRAPH

Indicate the Number of Bar -> #NUMBER_OF_GROUPS = 3

Groups and Samples in the #NUMBER_OF_SAMPLES = 5

bar graph.

Specify the various graph -> #DRAW_COLOR = 15

Colors and Fill Colors-- #BKG_COLOR = 0

if not specified here, the #FILL_COLORS = 12 ^ 13 ^ 14 ^

current values for these

parameters in memory will

be used. There are 3 bar

groups, so 3 fill-colors

are used. Bright red (12)

is used in the 1st bar

group, Bright magenta (13)

in the 2nd, and Yellow

(14) is used in the third.

We use a bright-white

border (15), and a black

(0) background color.

Provide legend, item, and -> #MAIN_TITLE = Av. Rain., Jan-May^

main graph titles. There #LEGEND_TITLES = Chic.^ NY ^Seattle^

are 3 group legends and 5 #ITEM_TITLES = Jan^Feb^Mar^Apr^May^

item samples (words are

abbreviated in the titles

here to allow lines to fit

on this page, but the file

uses the complete strings).

Indicate that a 3-D [not a -> #OPTIONS = 3D ^ AUTO ^

2-D graph] will be drawn.

Use automatic [not manual,

usr- specifie]e bar heigh,
