side (PLCHAR_VECTOR(3plplot), input)
An ascii character string specifying the side of the viewport along which the text is to be
written. The string must be one of: b: Bottom of viewport, text written parallel to edge. bv:
Bottom of viewport, text written at right angles to edge. l: Left of viewport, text written
parallel to edge. lv: Left of viewport, text written at right angles to edge. r: Right of
viewport, text written parallel to edge. rv: Right of viewport, text written at right angles to
edge. t: Top of viewport, text written parallel to edge. tv: Top of viewport, text written at
right angles to edge.
disp (PLFLT(3plplot), input)
Position of the reference point of string, measured outwards from the specified viewport edge in
units of the current character height. Use negative disp to write within the viewport.
pos (PLFLT(3plplot), input)
Position of the reference point of string along the specified edge, expressed as a fraction of the
length of the edge.
just (PLFLT(3plplot), input)
Specifies the position of the string relative to its reference point. If just=0. , the reference
point is at the left and if just=1. , it is at the right of the string. Other values of just give
intermediate justifications.
text (PLCHAR_VECTOR(3plplot), input)
A UTF-8 character string to be written out.
