       This function is used in examples 8,11,18,21.

ARGUMENTS

       xopt (const char *, input)
              Pointer to character string specifying options for  the  x  axis.  The  string  can
              include  any  combination  of  the  following  letters (upper or lower case) in any
              order: b: Draws axis at base, at height z=zmin where zmin is  defined  by  call  to
              plw3d(3plplot).   This character must be specified in order to use any of the other
              options.  f: Always use fixed point numeric labels.  i: Inverts tick marks, so they
              are  drawn  downwards,  rather than upwards.  l: Labels axis logarithmically.  This
              only affects the labels, not the data, and  so  it  is  necessary  to  compute  the
              logarithms  of  data points before passing them to any of the drawing routines.  n:
              Writes numeric labels at major tick intervals.  o: Use custom labelling function to
              generate  axis  label  text.  The custom labelling function can be defined with the
              plslabelfunc(3plplot) command.  s: Enables subticks between major ticks, only valid
              if  t  is also specified.  t: Draws major ticks.  u: If this is specified, the text
              label for the axis is written under the axis.

       xlabel (const char *, input)
              Pointer to character string specifying text label for the x axis.  It is only drawn
              if u is in the xopt string.

       xtick (PLFLT, input)
              World  coordinate interval between major ticks on the x axis. If it is set to zero,
              PLplot automatically generates a suitable tick interval.

       nxsub (PLINT, input)
              Number of subintervals between major x axis ticks for minor ticks.  If it is set to
              zero, PLplot automatically generates a suitable minor tick interval.

       yopt (const char *, input)
              Pointer  to  character  string  specifying  options  for  the y axis. The string is
              interpreted in the same way as xopt.

       ylabel (const char *, input)
              Pointer to character string specifying text label for the y axis.  It is only drawn
              if u is in the yopt string.

       ytick (PLFLT, input)
              World  coordinate interval between major ticks on the y axis. If it is set to zero,
              PLplot automatically generates a suitable tick interval.

       nysub (PLINT, input)
              Number of subintervals between major y axis ticks for minor ticks.  If it is set to
              zero, PLplot automatically generates a suitable minor tick interval.

       zopt (const char *, input)
              Pointer  to  character  string  specifying  options  for the z axis. The string can
              include any combination of the following letters  (upper  or  lower  case)  in  any
              order:  b:  Draws  z  axis to the left of the surface plot.  c: Draws z axis to the
              right of the surface plot.  d: Draws grid lines parallel to the  x-y  plane  behind
              the   figure.    These   lines   are  not  drawn  until  after  plot3d(3plplot)  or
              plmesh(3plplot) are called because of the need for hidden line removal.  f:  Always
              use fixed point numeric labels.  i: Inverts tick marks, so they are drawn away from
              the center.  l: Labels axis logarithmically.  This only affects the labels, not the
              data,  and  so  it  is  necessary  to  compute the logarithms of data points before
              passing them to any of the drawing routines.  m: Writes  numeric  labels  at  major
              tick  intervals on the right-hand vertical axis.  n: Writes numeric labels at major
              tick intervals on the left-hand vertical axis.  o: Use custom labelling function to
              generate  axis  label  text.  The custom labelling function can be defined with the
              plslabelfunc(3plplot) command.  s: Enables subticks between major ticks, only valid
              if  t  is also specified.  t: Draws major ticks.  u: If this is specified, the text
              label is written beside the left-hand axis.  v: If  this  is  specified,  the  text
              label is written beside the right-hand axis.

       zlabel (const char *, input)
              Pointer to character string specifying text label for the z axis.  It is only drawn
              if u or v are in the zopt string.

       ztick (PLFLT, input)
              World coordinate interval between major ticks on the z axis. If it is set to  zero,
              PLplot automatically generates a suitable tick interval.

       nzsub (PLINT, input)
              Number of subintervals between major z axis ticks for minor ticks.  If it is set to
              zero, PLplot automatically generates a suitable minor tick interval.
