  \brief Does the actual scaling
  \return Number of intervals after rescaling. This will in the most cases differ
  from the requested interval number!  Always >0.
  \param a Start value after scaling (always >= start)
  \param b Stop value after scaling  (always <= stop)

Parameters

start	Start value
stop	Stop value
ivals	Requested intervals

Returns

Number of intervals after autoscaling

  If the given interval has zero length the function returns the current
  interval number and a and b remain unchanged.
