Auto scaling may be set individually on the x, y or z axis
 or globally on all axes. The default is to autoscale all axes.

 When autoscaling, the plot range is automatically computed and the
 dependent axis (y for a  plot and z for  splot) is scaled to
 include the range of the function or data being plotted.

 If autoscaling of the dependent axis (y or z) is not set, the
 current y or z range is used.

 See  set yrange or  set zrange.

 Autoscaling the independent variables (x for  plot and x,y for
  splot) is a request to set the domain to match any data file being
 plotted. If there are no data files then autoscaling an independent
 variable has no effect. In other words, in the absence of a data
 file, functions alone do not affect the x range (or the y range if
 plotting z = f(x,y)).

 See  set xrange, or  set yrange.

 The behavior of autoscaling remains consistent in parametric mode,
 however, there are more dependent variables and hence more control
 over x, y, and z plot scales. In parametric mode, the independent or
 dummy variable is t for  plots and u,v for  splots.  Autoscale in
 parametric mode, then, controls all ranges (t, u, v, x, y, and z) and
 allows x, y, and z to be fully autoscaled.

 See  set parametric.

 Syntax:
         set autoscale 
         set noautoscale 
         show autoscale

 where  is either x, y, z or xy. If  is not given
 then all axes are assumed.

 Examples:

 This sets autoscaling of the y axis. x axis autoscaling is not
 affected.
         set autoscale y

 This sets autoscaling of the x and y axes.
         set autoscale xy

 This sets autoscaling of the x, y and z axes.
         set autoscale

 This disables autoscaling of the x, y and z axes.
         set noautoscale

 This disables autoscaling of the z axis only.
         set noautoscale z
