NAME

       GSWN (Set window) - establishes a window, or rectangular subspace, of world coordinates to
       be plotted. Calls to GSWN are  discouraged  with  NCAR  Graphics.  Instead,  use  the  SET
       subroutine because SET also supports mirror imaging and log scaling of axes.

SYNOPSIS

       CALL GSWN (TRNUM, XMIN, XMAX, YMIN, YMAX)

C-BINDING SYNOPSIS

       #include <ncarg/gks.h>

       void gset_win(Gint tran_num, const Glimit *win_limits);

DESCRIPTION

       TRNUM       (Integer,  Input)  -  A  normalization  transformation  number.  The number of
                   available transformations is implementation specific.  In  the  case  of  NCAR
                   GKS-0A, two normalization transformations are provided:

                   0      Selects  the  identity  transformation  in  which  both  the window and
                          viewport have the range of 0. to 1. in both coordinate directions. This
                          is  the  default normalization transformation for GKS. It is also fixed
                          within GKS; that is, it is illegal to call GSWN with TRNUM = 0.

                   1      A normalization transformation in which the window is defined  by  XMIN
                          to XMAX and YMIN to YMAX.

       XMIN        (Real, Input) - The left horizontal coordinate of the window.  XMIN < XMAX

       XMAX        (Real, Input) - The right horizontal coordinate of the window.

       YMIN        (Real, Input) - The bottom vertical coordinate of the window. YMIN < YMAX

       YMAX        (Real, Input) - The top vertical coordinate of the window.

ACCESS

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