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.
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.

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 If the /ERRFILL qualifier is used with the READ/VECTOR command, 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: hnum { spacevec angle }
The GET HATCH command obtains 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 is used for changing the hatch pattern definitions, but does
not choose the hatch pattern to be used by other commands.
If just the keyword HATCH is entered, a table of the spacings and angles
for all ten hatch patterns is displayed. If the hatch pattern number,
hnum, is entered, then only pattern hnum will be displayed. If the hatch
pattern number, an output vector and an output scalar are entered, then
the vector will contain the spacings and the scalar will contain the
angle for that pattern number.
1 <= hnum <= 10 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 information 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 GET LINES command is used for obtaining the definition of the line
types that are used by the commands: GRAPH, LINE, PICK, ELLIPSE, FIGURE,
and ZEROLINES. The SET LINES command is used for changing the definition
of the line types. This command does NOT choose the line type to be used
by other commands, but 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 10
line types is displayed. If the line type number, n, and an output vector,
v, are entered, then nothing will be displayed. For example, to get line
type 2 into vector X2, enter: GET LINE 2 X2
See the SET LINES command for information on how the line types are
defined. There are ten line types available. The lengths are expressed
in centimeters, the default, 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 information on how to display examples of the line
types.
Default value: TENSION = 1 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 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 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.
This is the program version date. It is character valued, with a length of 20.
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 The value of the FONT keyword is a character string. So, if you enter: GET FONT X, the variable X will be a text variable. FONT is the graphics font. Use the DISPLAY FONT command to draw a font table.
Additional Information on:
The value of the DEVICE keyword is a character string. So, if you enter: GET DEVICE X, the variable X will be a text variable. DEVICE is the hardcopy device name. Use the DEVICE command to change the hardcopy device type.
Default units type: CM ( centimeters ) The value of the UNITS keyword is a character string. So, if you enter: GET UNITS X, the variable X will be a scalar text variable. UNITS is the plotting units type, either centimeters, CM, the default, or inches, IN.
Default: PERCENT ( % of the current window ) The value of the CUNITS keyword is a character string. So, if you enter: GET CUNITS X, the variable X will be a scalar text variable. CUNITS is 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: GET PCHAR P
GET PCHAR P PS PC PA
GET PCHAR obtains the plotting symbol values or arrays, as set with the
SET PCHAR command. It is not necessary to set the size, colour or angle
with the SET PCHAR command, but if these are not set, you cannot request
their values. The type of output variable that will be made for each
parameter depends on the type of variable used in the SET PCHAR command.
