NAME

       gset_char_up_vec  (Set character up vector) - specifies the angle at which subsequent text
       is to be drawn with gtext.

SYNOPSIS

       #include <ncarg/gks.h>

       void gset_char_up_vec(const Gvec *char_up_vec);

DESCRIPTION

       char_up_vec.delta_x
                   (Gfloat, Input) - Gives the X (horizontal) world coordinate of a vector.

       char_up_vec.delta_y
                   (Gfloat, Input) - Gives the Y (vertical) world coordinate of a vector.

USAGE

       The coordinates (char_up_vec.delta_x, char_up_vec.delta_y) relative to the  point  (0.,0.)
       establish  a  vector  direction.   This direction specifies the up direction of individual
       characters.  This direction also specifies the orientation of a text string  in  that  the
       characters  in  a string are placed along a line perpendicular to the character up vector.
       By default the character up vector is (0.,1.) so that characters are drawn in their normal
       horizontal  orientation.   The  magnitude of the up vector is not used so that (0.,23.) is
       the same as (0.,1.).

EXAMPLES

             char_up_vec.delta_x = -1.
             char_up_vec.delta_y = 0.
             gset_char_up_vec(&char_up_vec);

       would specify the character up vector as (-1.,0.) and subsequent text written  with  gtext
       would be rotated 90 degrees from normal and would be appropriate for a Y-axis label.

             char_up_vec.delta_x = 1.
             char_up_vec.delta_y = 1..
             gset_char_up_vec(&char_up_vec);

       would  specify  the  character up vector as (1.,1.) and subsequent text written with gtext
       would be rotated -45 degress from normal.
