void axesoff(noaxes) GRIDOPTS.C Level 1
char noaxes noaxes is a bit variable with the bits assigned as follows:
 
Bit Logical Name Effect
0
  GPC_AXESON
 GPC_AXESOFF		  0 = axes and labels on
 1 = axes and labels off
1
  GPC_XAXIS  x axis with no labels
2
  GPC_YAXIS  y axis with no labels
3
 GPC_ XLAB  x axis lables
4
  GPC_YLAB  y axis labels
 
axesoff() allows you to draw plots with no axes or axis labels. Either scales() or graf() must still be called so that 
GraphiC can calculate the limits for the plot. axesoff() must be called before any routines that draw the axes, e.g., graf() or scales(). axesoff() can also be used with 3-D routines, but only the GPC_AXESON / GPC_AXESOFF flag is used. Note that axesoff() only turns off the axes and labels. Grid lines (and fine grid lines) will still be drawn if those options are active. 

Calling axesoff(0) enables both axes with labels, which is the default. For example, to draw the x axis with labels and the y axis without labels call 

axesoff( GPC_XAXIS | GPC_XLAB | GPC_YAXIS)
To turn all axes and labels on (default) call 
axesoff(GPC_AXESON)
To turn all axes and labels off call 
axesoff(GPC_AXESOFF).
axesoff(GPC_AXESON) is equivalent to axesoff(GPC_XAXIS | GPC_XLAB | GPC_YAXIS | GPC_YLAB).
