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.

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, 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.

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