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
       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.

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.
