wrt 705, “SM character”
NOTE
Some symbols in the following text are not else-
where defined in this manual.
Refer to Hewlett -
Packard operating manuals for complete symbol
d e f i n i t i o n s .
Symbol mode command,
"SM", is used with PA and PR commands and
provides the means to draw a symbol at the end of each vector.
Symbol is limited to a single character and may be any print-
ing character except: (ASCII 59). PA and PR commands function
as usual, except that the specified character is drawn at the
end of each vector and is centered on the plotted point.
Character will be drawn at the end of the vector whether the
pen is up or down.
Character is drawn according to the
character set currently selected when the SM instruction is
executed.
Once selected, the character is independent of
character set changes later in the program and can only be
changed by a new SM command.
I f a c h a r a c t e r i s n o t s p e c i f i ed
the symbol mode is cancelled. If a non-printing or control
character is specified, error 3 is set and the symbol mode
i s c a n c e l l e d.
The size (SI and SR), slant (SL), and direction
(DI and OR) commands affect the character drawn. An SM com-
mand remains in effect until another SM command is executed
o r t h e p l o t t e r i s i n i t i a l i z e d o r s e t t o d e f a u l t c o n d i t i o n s.
Since symbol mode can only be used with a single symbol, when-
ever a label requires more than one symbol, CP instructions
must be used.
wrt 705, " T L [Up and right tic length
[ , d o w n a n d l e f t t i c l e n g t h ] ] ”
Tic length command,
"TL", specifies length of tic marks drawn
by axis statements.
Tic lengths are specified as percentage
of horizontal and vertical distances between scaling points P1
and P2.
Up and right tic length determines length of upward portion of
tic marks to be drawn along X-axis and right side portion of
tic marks to be drawn along Y-axis. This value is specified
a s p e r c e n t a g e o f v e r t i c a l s c a l e l e n g t h , P1y - P2Y .
