NAME

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

SYNOPSIS

       CALL GSCHUP (CHUX, CHUY)

C-BINDING SYNOPSIS

       #include <ncarg/gks.h>

       void gset_char_up_vec(const Gvec *char_up_vec);

DESCRIPTION

       CHUX        (Real, Input) - Gives the X (horizontal) world coordinate of a vector.

       CHUY        (Real, Input) - Gives the Y (vertical) world coordinate of a vector.

USAGE

       The coordinates (CHUX, CHUY) 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

             CALL GSCHUP(-1.,0.)

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

             CALL GSCHUP(1.,1.)

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

ACCESS

       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
