code: def same_log10_order_of_magnitude(x, delta=0.1):
      
      dmin = np.log10(np.min(x)*(1-delta))
      dmax = np.log10(np.max(x)*(1+delta))

docs: Return true if range is approximately in same order of magnitude
  
      For example these sequences are in the same order of magnitude:
  
          - [1, 8, 5]     # [1, 10)
          - [35, 20, 80]  # [10 100)
          - [232, 730]    # [100, 1000)
  
      Parameters
      ----------
      x : array-like
           Values in base 10. Must be size 2 and
          ``rng[0] <= rng[1]``.
      delta : float
          Fuzz factor for approximation. It is multiplicative.
