Default value: ARROLEN = 0.20 Arrow head length as a fraction of the total arrow length. Used for arrows drawn with the FIGURE command.
Default value: ARROTYP = 00
The type of arrow drawn with the FIGURE command.
ARROTYP = 00 - open head, line segment with arrowhead at one end
01 - open head, line segment with arrowhead at each end
02 - open head, no line segment
10 - closed head, line segment with arrowhead at one end
11 - closed head, line segment with arrowhead at each end
12 - closed head, no line segment
Default value: ARROWID = 0.15 Arrow head width as a fraction of the total arrow length. Used for arrows drawn with the FIGURE command.
Syntax: SET AUTOSCALE keyword{\qualifier}
Keywords: ON, OFF, COMMENSURATE, XAXIS, YAXIS
Qualifiers: \VIRTUAL
Defaults: both x- and y-axes autoscaled, \-VIRTUAL
The AUTOSCALE keyword controls autoscaling for graph axes.
Autoscaling remains in effect until either the command
SET AUTOSCALE OFF is entered, or the SCALES command is entered.
Autoscaling affects commands that draw axes, e.g., the commands
GRAPH, CONTOUR, DENSITY, REPLOT, and SLICES.
Autoscaling means to automatically choose the minimum and maximum
values for the axes, as well as the number of large, numbered,
tic marks for the axes. The type of autoscaling that is done
depends on the keyword that is used with the command.
Additional Information on:
Default value: CNTSEP = 9.5cm, %CNTSEP = 50. The separation between contour labels can be set with CNTSEP or %CNTSEP. If %CNTSEP is used, the separation is a percentage of the height of the window, that is, YUWIND-YLWIND. If CNTSEP is used, the separation is expressed in centimeters or inches, depending on the units type as set with the SET UNITS command.
Default value: LABSIZ = 0.285cm, %LABSIZ = 1.5 The size of the contour labels can be set with LABSIZ or %LABSIZ. If %LABSIZ is used, the size is a percentage of the height of the window, that is, YUWIND-YLWIND. If LABSIZ is used, the size is expressed in centimeters or inches, depending on the units type as set with the SET UNITS command.
Default value: LEGSIZ = 0.304cm, %LEGSIZ = 1.6 The size of numeric legend entries in CONTOUR and DENSITY commands. It can be set as LEGSIZ or %LEGSIZ. If %LEGSIZ is used, the size is a percentage of the height of the window, that is, YUWIND-YLWIND. If LEGSIZ is used, the size is expressed in centimeters or inches, depending on the units type as set with the SET UNITS command.
Default value: LEGFRMT = `1PE10.3' The format used for the numeric legend values in the DENSITY command and for the contour levels in the CONTOUR legend.
Default value: ERRFILL = 0.0 If the \ERRFILL qualifier is used when reading vectors, an invalid field in the data file causes either the entire record to be filled with the value of ERRFILL if a format is used, or only that invalid field will be filled with ERRFILL if no format is used.
FILL is used in the FIGURE command with BOX, POLYGON, WEDGE, CIRCLE,
ELLIPSE, and ARROWs with closed heads. It is also used with the
DENSITY\BOXES command to fill the boxes. Default value: FILL=0
FILL = 0 no filling (the default)
1 <= |FILL| <= 10 fill with hatch pattern
11 <= |FILL| <= 99 fill with dithering pattern nm, where n is the
increment number of dots to light up horizontally
and m is the increment number of dots to light up
vertically.
FILL < 0, then erase using |FILL|

Parameters: n { v a }
The SET HATCH command changes the hatch pattern definitions that are
used for text bolding, for filling areas under curves or histograms,
and for use by the TILE, PIEGRAPH, and FIGURE commands. The SET HATCH
command does not choose the hatch pattern to be used by other commands,
but only alters the definition of a hatch pattern.
If just the keyword HATCH is entered, a table of the spacings and
angles for all ten hatch patterns is displayed. You will be requested
to enter a hatch pattern number, n, a vector of spacings, v, and an
angle, a. Typing the <RETURN> key, without entering anything, will leave
the current values unchanged. If the hatch pattern number, a spacing
vector and an angle are entered, then nothing will be displayed.
1 <= n <= 10. v should have from 1 to 10 elements.
A hatch pattern is composed of an angle and from 1 to 10 spacings.
The angles are in degrees and the spacing lengths, are expressed in
centimeters, but if the units are changed to inches, with the SET UNITS
command, the lengths will be converted to inches. See the DISPLAY
command for info. on how to display examples of the hatch patterns.
When an object is being filled, a line is drawn inside the object at
the specified angle, then a parallel line is drawn at the first spacing,
and so on for the number of spacings in that pattern. This process is
repeated until the object is filled.
Parameters: n { v }
The SET LINES command is used for changing the definition of the line
types that are used by the commands: GRAPH, LINE, PICK, ELLIPSE, FIGURE,
and ZEROLINES. This command does not choose the line type to be used by
other commands. It only alters the definition of a line type. To choose
a line type, use the SET LINTYP command.
If just the keyword LINES is entered, a table of the spacings for all
ten line types is displayed. You will be requested to enter a line type
number, n, and a vector of spacings, v. Typing the <RETURN> key, without
entering anything, will leave the current values unchanged. If the line
type number and a spacing vector are entered, then nothing will be
displayed. For example, to set line type 2 to [0.05;0;0], enter:
SET LINE 2 [0.05;0;0]
1 <= n <= 10. v must have 3 elements. The line types come in 4 different
styles: ordinary solid line; double line of specified width; dashed line
with specified dash and space lengths; dashed line with 2 different dash
lengths.
v[1] v[2] v[3]
= 0 solid line:
> 0 = 0 double line: seperation v[1]
> 0 > 0 = 0 dashed line: dash length v[1], space length v[2]
> 0 > 0 > 0 dashed line: 1st dash length v[1], space length v[2],
2nd dash length v[3]
Default value: TENSION = 1.0 TENSION controls the spline tension for the functions using cubic splines: DERIV, INTEGRAL, INTERP, SMOOTH, SPLINTERP, SPLSMOOTH.
Default value: SEED = 12345 SEED is the random number seed value. This seed is updated whenever the GENERATE\RANDOM command is entered, or the RAN function is used.
Default value: POSTRES = 180 POSTRES controls the PostScript graphics output resolution in dots/inch. This applies to dot filled text characters and DENSITY plots. The resolution can be changed at any time, so different parts of a single drawing can be drawn with different resolutions.
Default value: SPEED = 20 SPEED controls the pen plotter speed. This applies to Hewlett-Packard, Houston, and Roland RDGL II pen plotters. The speed can be changed at any time, so different parts of a single drawing can be drawn at different speeds.
Default value: 80 WIDTH, 2 <= WIDTH <= 132, controls the character width of the alphanumeric monitor screen, and is equivalent to the DCL command: $SET TERMINAL/WIDTH=n
Default value: 0 XPREV is the last world x-coordinate that was drawn to by any graphics command. The value of this keyword is automatically updated.
Default value: 0 YPREV is the last world y-coordinate that was drawn to by any graphics command. The value of this keyword is automatically updated.
Default value: 0 NCURVES is the total number of data curves that have been drawn, using the GRAPH command, since the last CLEAR command. The value of this keyword is automatically updated.
This is the program version number. It is character valued, with a length of 5. The version number cannot be changed.
This is the program version date. It is character valued, with a length of 20. The version date cannot be changed.
Default value: SHOWHISTORY = 5
SHOWHISTORY controls how many lines of history to display for each
numeric variable as a result of the SHOW command.
SHOWHISTORY
n < 0 --> all stored history lines will be displayed
n = 0,1 --> only the latest history line will be displayed
n > 0 --> a maximum of n lines of history will be
displayed for each variable
Default value: MAXHISTORY = 5 SHOWHISTORY is the number of history lines to display for each numeric variable with the SHOW command. MAXHISTORY is the maximum number of history lines to store for each numeric variable, and its default is 5. MAXHISTORY was added because if a variable had its value changed within a large DO loop, a new history line was added each time the loop was processed. This could lead to virtual memory problems.
Default value: WRAP = 0 If WRAP = 0, history lines and character variable contents lines are not wrapped when displayed with the SHOW command. If WRAP is non-zero, these lines are wrapped.
Default font: TSAN FONT is the graphics font. Use the DISPLAY FONT command to draw a font table.
Additional Information on:
Parameters: CM | IN Default units: CM ( centimeters ) The SET UNITS command selects the plotting units type, either centimeters, CM, the default, or inches, IN.
Parameters: GRAPH | PERCENT | WORLD Default units: PERCENT ( % of the current window ) The SET CUNITS command selects the units type for the cursor readout when the graphics cursor is invoked by the PICK, PEAK, LINE, or FIGURE command when running under X windows and mouse button 2 is pressed. If WORLD is chosen, the numbers displayed depend on the current units type, either CM or IN, as chosen with SET UNITS. If GRAPH is chosen, the numbers displayed depend on the current graph axis scales.
Parameters: sym { size { colour { angle }}}
Examples: SET PCHAR -1
SET PCHAR P
SET PCHAR P PS PC
SET PCHAR P 1.5 PC 45
SET PCHAR controls the plotting symbols, or the appearance of the
histogram bars, when the GRAPH command is entered. Entering a constant
or a scalar is similar to entering a vector whose elements are all
equal to the constant or the scalar. The interpretations of the
parameters depend on the value of the GPLOT keyword HISTYP at the time
that the GRAPH command is entered. HISTYP can be changed with the SET
command. If HISTYP=0, the default value, subsequent graphs will be
normal line graphs.
