Set the Attributes of TAGs

/bg_co$*$lor=int_expr

The text background colour. See table in section 15.3.69.

/co$*$lor=int_expr

The tag colour. See table in section 15.3.69.

/di$*$stance=float_expr

The distance between the text and the symbol [NDC].

/fo$*$nt=int_expr

Character set number, see the table in section 15.3.69.

/fr$*$ame=int_expr

0 - NDC, normalized device coordinates, from 0 to 1. 1 - world coordinates

/he$*$ight=float_expr

The font height.

/h_$*$align=int_expr

Horizontal alignment

0 - Normal 1 - Left 2 - Center 3 - Right

/par$i$=val, i=1,5

PAR1 is used by for the display of rectangles and ellipses. It defines the ratio of the lengths in x- and y-direction.

PAR2 is an angles that rotates the symbols.

/pr$*$ec=int_expr

The character size [points] for which the font was calculated. It is recommended to set it to 0.

/si$*$ze=float_expr

Line thickness or marker size.

/st$*$ring=text_expr

The text string.

/st$*$ring=nil

Generates an empty string, for internal purposes.

/tag_s$*$ize=float_expr

The size of the graphical symbol.

/tag_t$*$ype=int_expr

See the table in section 15.12.

/ty$*$pe=int_expr

Line type or marker type, see the table 15.3.69, 15.11.

/ux=float_expr

/uy=float_expr

The up-vector. Used to rotate the text.

/x$*$_pos=float_expr

/y$*$_pos=float_expr

The position of the TAG. For left aligned texts, it is the starting point of the text.

e.g.:

SPECTRA> create/notext sn 0 10 100

SPECTRA> create/notext cs 0 10 100

SPECTRA> set cs/type=2

SPECTRA> create/tag sn

SPECTRA> create/tag/y=0.82 cs

SPECTRA> calc sn = sinus(sin)

SPECTRA> calc cs = cosinus(sin)

SPECTRA> display
See the output in the figure in section 15.3.69. Note that a TAG chooses its symbol type from the SCAN that is already in the slot.
