PLVPOR(3)                   PLplot API                  PLVPOR(3)


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(3) in order to  cre-
       ate 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.

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 view-
              port.
