AGPWRT - Provides a way for the user to change the style of all
text strings drawn by Autograph.
SUBROUTINE AGPWRT (XPOS,YPOS,CHRS,NCHS,ISIZ,IORI,ICEN)
- XPOS
- (an input expression of type REAL) is the X coordinate of a point relative
to which the text string is to be positioned.
- YPOS
- (an input expression of type REAL) is the Y coordinate of a point relative
to which the text string is to be positioned.
- CHRS
- (an input expression of type CHARACTER) is the text string to be
drawn.
- NCHS
- (an input expression of type INTEGER) is the length of CHRS - the number
of characters in the text string.
- ISIZ
- (an input expression of type INTEGER) specifies the size of the characters
to be used. The values 0, 1, 2, and 3 imply character widths of 8, 12, 16,
and 24 plotter units, respectively. Larger values specify the character
width directly.
- IORI
- (an input expression of type INTEGER) is the orientation angle of the text
string, measured in degrees counter-clockwise from a vector which is
horizontal and pointing to the right.
- ICEN
- (an input expression of type INTEGER) is the centering option. The value
"-1" implies that the text is to be written with (XPOS,YPOS) in
the center of the left edge of the leftmost character, the value
"0" that (XPOS,YPOS) is to be in the center of the entire
string, and the value "+1" that (XPOS,YPOS) is to be in the
center of the right edge of the rightmost character.
This routine is not called by the user program, but by Autograph
itself, to draw a numeric label or an informational label on the graph. The
default version just calls the plot-package routine PWRIT. The user may
supply a replacement version.
Note: A user version of AGPWRT should not call any other Autograph
routine.
To use AGPWRT, load the NCAR Graphics libraries ncarg, ncarg_gks,
and ncarg_c, preferably in that order.
