Set the Attributes of TEXTs

/bg_color=int_expr: The text background colour. See table in section 15.3.69.
/color=int_expr: The text colour. See table in section 15.3.69.
/exfactor=float_expr: The expansion factor.
/font=int_expr: Character set number, see the table in section 15.3.69 for the fonts and the table in section 15.3.69 for the available symbols. A symbol can be selected by:
SPECTRA> set 1.4/string="Wavelength[\angstroem{}]"

The loaded fonts can be inspected by:
SPECTRA> show x11/font
/frame=int_expr: 0 - normalized device coordinates, from 0 to 1. 1 - world coordinates
/h_align=int_expr: Horizontal alignment
0 - Normal 1 - Left 2 - Center 3 - Right
/height=int_expr: The text height [pixel], default 17.
The appearance of the TEXTs depends also on the /map_mode attribute of the LAYOUT.
/prec=int_expr: The character size [points] for which the font was calculated. It is recommended to set it to 0.
/string=text_expr: The text string.
/ux=float_expr
/uy=float_expr: The up-vector. Used to rotate the text.
/v_align=int_expr: Vertical alignment
0 - Normal 1 - Top 2 - Cap 3 - Half 4 - Base 5 - Bottom
/x=float_expr
/y=float_expr: The position of the text string. Depending on the value of the /frame flag is it measured in normalized device coordinates or world coordinates.
e.g.:
: SPECTRA> set bpu1.4/y=1.1
Sets the y-position of a TEXT.
