2 INCLUDE
  Syntax: INCLUDE xlo xhi
      or  INCLUDE axis xlo xhi
   where: axis  is the axis name (defaults are x and y)
          xlo   is the lower limit of the inclusion
          xhi   is the upper limit of the inclusion

  Includes a region of the histogram to be fit.  If you are fitting a
  2-D histogram, you must specify which axis the inclusion applies
  to. If you omit the axis name the default is the x-axis. If you are
  fitting more than one histogram simultaneously, you will be prompted
  for which histogram the inclusion applies to. If you just give the
  command `INCLUDE', you can give several regions to include, then hit
  `<CR>' to exit `INCLUDE'.
