Draws axes, numeric and text labels for a three-dimensional surface plot. For a more complete description of three-dimensional plotting see the section called “Three-dimensional Plots”.
xopt
	  (PLCHAR_VECTORAn ascii 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= where
		  zminzminplw3d.  This character must be specified in
		  order to use any of the other options.
		
		  d: Plot labels as date / time.
		  Values are assumed to be seconds since the epoch
		  (as used by gmtime).
		
		  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 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
	  (PLCHAR_VECTOR
	    A UTF-8 character string specifying
	    the text label for the x
	    axis.  It is only drawn if u is in the
	    xopt
xtick
	  (PLFLTWorld coordinate interval between major ticks on the x axis. If it is set to zero, PLplot automatically generates a suitable tick interval.
nxsub
	  (PLINTNumber 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
	  (PLCHAR_VECTOR
	    An ascii character string specifying options for the y axis.
	    The string is interpreted in the same way as
	    xopt
ylabel
	  (PLCHAR_VECTOR
	    A UTF-8 character string specifying the text label for the y
	    axis.  It is only drawn if u is in the
	    yopt
ytick
	  (PLFLTWorld coordinate interval between major ticks on the y axis. If it is set to zero, PLplot automatically generates a suitable tick interval.
nysub
	  (PLINTNumber 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
	  (PLCHAR_VECTORAn ascii 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 or plmesh are called because of
		  the need for hidden line removal.
		
		  e: Plot labels as date / time.
		  Values are assumed to be seconds since the epoch
		  (as used by gmtime).  Note this suboption is interpreted
                  the same as the d suboption for
                  xoptyopte for
                  zoptd has already been used for the
                  different purpose above.
		
		  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 z axis.
		
		  n: Writes numeric labels at major tick
		  intervals on the left-hand z axis.
		
		  o: Use custom labelling function to
		  generate axis label text.  The custom labelling function
		  can be defined with the plslabelfunc 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
	  (PLCHAR_VECTOR
	    A UTF-8 character string specifying the text label for the z
	    axis.  It is only drawn if u or
	    v are in the
	    zopt
ztick
	  (PLFLTWorld coordinate interval between major ticks on the z axis. If it is set to zero, PLplot automatically generates a suitable tick interval.
nzsub
	  (PLINTNumber of subintervals between major z axis ticks for minor ticks. If it is set to zero, PLplot automatically generates a suitable minor tick interval.
