GSWN (Set window) - establishes a window, or rectangular subspace, of world coordinates to be plotted.

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

       #include <ncarg/gks.h>

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

       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.

       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.
