NAME

6       plsdiori - Set plot orientation
7

SYNOPSIS

9       plsdiori(rot)
10

DESCRIPTION

12       Set  plot  orientation  parameter  which is multiplied by 90 degrees to
13       obtain the angle of rotation.  Note, arbitrary rotation parameters such
14       as 0.2 (corresponding to 18 degrees) are possible, but the usual values
15       for the rotation parameter are 0., 1., 2., and 3.  corresponding  to  0
16       degrees  (landscape  mode),  90  degrees  (portrait  mode), 180 degrees
17       (seascape  mode),  and  270  degrees  (upside-down  mode).    If   pls‐
18       diori(3plplot) is not called the default value of rot is 0.
19
20       N.B.  aspect ratio is unaffected by calls to plsdiori(3plplot).  So you
21       will probably want to change the aspect ratio to a value  suitable  for
22       the  plot orientation using a call to plsdidev(3plplot) or the command-
23       line options -a  or  -freeaspect.   For  more  documentation  of  those
24       options see the PLplot documentation.  Such command-line options can be
25       set internally using plsetopt(3plplot) or set directly using  the  com‐
26       mand line and parsed using a call to plparseopts(3plplot).
