NAME

6       plvpas - Specify viewport using coordinates and aspect ratio
7

SYNOPSIS

9       plvpas(xmin, xmax, ymin, ymax, aspect)
10

DESCRIPTION

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

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

22       This function is used in example 9.

ARGUMENTS

25       xmin (PLFLT(3plplot), input)
26              The  normalized  subpage coordinate of the left-hand edge of the
27              viewport.
28
29       xmax (PLFLT(3plplot), input)
30              The normalized subpage coordinate of the right-hand edge of  the
31              viewport.
32
33       ymin (PLFLT(3plplot), input)
34              The  normalized  subpage  coordinate  of  the bottom edge of the
35              viewport.
36
37       ymax (PLFLT(3plplot), input)
38              The normalized subpage coordinate of the top edge of  the  view‐
39              port.
40
41       aspect (PLFLT(3plplot), input)
42              Ratio of length of y axis to length of x axis.
