NAME

       plvpor - Specify viewport using coordinates

SYNOPSIS

       plvpor(xmin, xmax, ymin, ymax)

DESCRIPTION

       Device-independent  routine  for  setting  up  the viewport.  This defines the viewport in
       terms of normalized subpage coordinates which run from 0.0  to  1.0  (left  to  right  and
       bottom  to  top)  along  each  edge  of  the  current  subpage.  Use the alternate routine
       plsvpa(3plplot) in order to create a viewport of a definite size.

       Redacted form: plvpor(xmin, xmax, ymin, ymax)

       This function is used in examples 2,6-8,10,11,15,16,18,21,23,24,26,27,31.

ARGUMENTS

       xmin (PLFLT, input)
              The normalized subpage coordinate of the left-hand edge of the viewport.

       xmax (PLFLT, input)
              The normalized subpage coordinate of the right-hand edge of the viewport.

       ymin (PLFLT, input)
              The normalized subpage coordinate of the bottom edge of the viewport.

       ymax (PLFLT, input)
              The normalized subpage coordinate of the top edge of the viewport.
