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.
