PLGDIORI(3plplot) PLplot API PLGDIORI(3plplot)NAME
plgdiori - Get plot orientation
SYNOPSIS
plgdiori(p_rot)
DESCRIPTION
Get 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 pls-
diori(3plplot) has not been called the default value pointed to by p_rot will be 0.
Redacted form: plgdiori(p_rot)
This function is not used in any examples.
ARGUMENTS
p_rot (PLFLT *, output)
Pointer to orientation parameter.

plsdiori - Set plot orientation
SYNOPSIS
plsdiori(rot)
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 pls-
diori(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).
Redacted form: plsdiori(rot)
This function is not used in any examples.
ARGUMENTS
rot (PLFLT, input)
Plot orientation parameter.
