Description

       Set  plot orientation parameter which is multiplied by 90 degrees to obtain the angle of rotation.  Note,
       arbitrary rotation parameters such as 0.2 (corresponding to 18  degrees)  are  possible,  but  the  usual
       values  for the rotation parameter are 0., 1., 2., and 3. corresponding to 0 degrees (landscape mode), 90
       degrees  (portrait  mode),  180  degrees  (seascape  mode),  and  270  degrees  (upside-down  mode).   If
       plsdiori(3plplot) is not called the default value of rot is 0.

       N.B.  aspect  ratio is unaffected by calls to plsdiori(3plplot).  So you will probably want to change the
       aspect ratio to a value suitable for the plot orientation  using  a  call  to  plsdidev(3plplot)  or  the
       command-line  options  -a  or  -freeaspect.   For  more  documentation  of  those  options see the PLplot
       documentation.  Such command-line options can be set internally using plsetopt(3plplot) or  set  directly
       using the command line and parsed using a call to plparseopts(3plplot).
