NAME

       plvpas - Specify viewport using coordinates and aspect ratio

SYNOPSIS

       plvpas(xmin, xmax, ymin, ymax, aspect)

DESCRIPTION

       Device-independent  routine  for  setting up the viewport.  The viewport is chosen to be the largest with
       the given  aspect  ratio  that  fits  within  the  specified  region  (in  terms  of  normalized  subpage
       coordinates).  This routine is functionally equivalent to plvpor(3plplot) when a ``natural'' aspect ratio
       (0.0) is chosen.  Unlike plvasp(3plplot), this routine reserves no extra space at the edges for labels.

       Redacted form: plvpas(xmin, xmax, ymin, ymax, aspect)

       This function is used in example 9.

ARGUMENTS

       xmin (PLFLT(3plplot), input)
              The normalized subpage coordinate of the left-hand edge of the viewport.

       xmax (PLFLT(3plplot), input)
              The normalized subpage coordinate of the right-hand edge of the viewport.

       ymin (PLFLT(3plplot), input)
              The normalized subpage coordinate of the bottom edge of the viewport.

       ymax (PLFLT(3plplot), input)
              The normalized subpage coordinate of the top edge of the viewport.

       aspect (PLFLT(3plplot), input)
              Ratio of length of y axis to length of x axis.
