6 AGPWRT - Provides a way for the user to change the style of all text
7 strings drawn by Autograph.

10 SUBROUTINE AGPWRT (XPOS,YPOS,CHRS,NCHS,ISIZ,IORI,ICEN)
11
13 XPOS (an input expression of type REAL) is the X coordinate of a
14 point relative to which the text string is to be
15 positioned.
16
17 YPOS (an input expression of type REAL) is the Y coordinate of a
18 point relative to which the text string is to be
19 positioned.
20
21 CHRS (an input expression of type CHARACTER) is the text string
22 to be drawn.
23
24 NCHS (an input expression of type INTEGER) is the length of CHRS
25 - the number of characters in the text string.
26
27 ISIZ (an input expression of type INTEGER) specifies the size of
28 the characters to be used. The values 0, 1, 2, and 3 imply
29 character widths of 8, 12, 16, and 24 plotter units,
30 respectively. Larger values specify the character width
31 directly.
32
33 IORI (an input expression of type INTEGER) is the orientation
34 angle of the text string, measured in degrees counter-
35 clockwise from a vector which is horizontal and pointing to
36 the right.
37
38 ICEN (an input expression of type INTEGER) is the centering
39 option. The value "-1" implies that the text is to be
40 written with (XPOS,YPOS) in the center of the left edge of
41 the leftmost character, the value "0" that (XPOS,YPOS) is
42 to be in the center of the entire string, and the value
43 "+1" that (XPOS,YPOS) is to be in the center of the right
44 edge of the rightmost character.
45
47 This routine is not called by the user program, but by Autograph
48 itself, to draw a numeric label or an informational label on the graph.
49 The default version just calls the plot-package routine PWRIT. The user
50 may supply a replacement version.
51
52 Note: A user version of AGPWRT should not call any other Autograph
53 routine.
54
56 To use AGPWRT, load the NCAR Graphics libraries ncarg, ncarg_gks, and
57 ncarg_c, preferably in that order.
