NAME

6       GSCHUP  (Set character up vector) - specifies the angle at which subse‐
7       quent text is to be drawn with GTX.
8

SYNOPSIS

10       CALL GSCHUP (CHUX, CHUY)
11

C-BINDING SYNOPSIS

13       #include <ncarg/gks.h>
14
15       void gset_char_up_vec(const Gvec *char_up_vec);
16

DESCRIPTION

18       CHUX        (Real, Input) - Gives the X (horizontal)  world  coordinate
19                   of a vector.
20
21       CHUY        (Real,  Input) - Gives the Y (vertical) world coordinate of
22                   a vector.
23

USAGE

25       The coordinates (CHUX, CHUY) relative to the point (0.,0.)  establish a
26       vector  direction.   This direction specifies the up direction of indi‐
27       vidual characters.  This direction also specifies the orientation of  a
28       text  string in that the characters in a string are placed along a line
29       perpendicular to the character up vector.  By default the character  up
30       vector is (0.,1.) so that characters are drawn in their normal horizon‐
31       tal orientation.  The magnitude of the up vector is not  used  so  that
32       (0.,23.) is the same as (0.,1.).
33

EXAMPLES

35             CALL GSCHUP(-1.,0.)
36
37       would  specify  the character up vector as (-1.,0.) and subsequent text
38       written with GTX would be rotated 90 degrees from normal and  would  be
39       appropriate for a Y-axis label.
40
41
42             CALL GSCHUP(1.,1.)
43
44       would  specify  the  character up vector as (1.,1.) and subsequent text
45       written with GTX would be rotated -45 degress from normal.
