PGPLOT Module: PGPTXT -- write text at arbitrary position and angle
SUBROUTINE PGPTXT (X, Y, ANGLE, FJUST, TEXT)
REAL X, Y, ANGLE, FJUST
CHARACTER*(*) TEXT
Primitive routine for drawing text. The text may be drawn at any
angle with the horizontal, and may be centered or left- or right-
justified at a specified position. Routine PGTEXT provides a
simple interface to PGPTXT for horizontal strings. Text is drawn
using the current values of attributes color-index, line-width,
character-height, and character-font. Text is NOT subject to
clipping at the edge of the window.
Arguments
X (input) : world x-coordinate.
Y (input) : world y-coordinate. The string is drawn with the
baseline of all the characters passing through
point (X,Y); the positioning of the string along
this line is controlled by argument FJUST.
ANGLE (input) : angle, in degrees, that the baseline is to make
with the horizontal, increasing counter-clockwise
(0.0 is horizontal).
FJUST (input) : controls horizontal justification of the string.
If FJUST = 0.0, the string will be left-justified
at the point (X,Y); if FJUST = 0.5, it will be
centered, and if FJUST = 1.0, it will be right
justified. [Other values of FJUST give other
justifications.]
TEXT (input) : the character string to be plotted.
