6 plvpas - Specify viewport using coordinates and aspect ratio

9 plvpas(xmin, xmax, ymin, ymax, aspect)
10
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.
23
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.
