docstr: Determines a formatting rule for the tick exponents. For
  example, consider the number 1,000,000,000. If "none", it
  appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If
  "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If
  "B", 1B.
  
  The 'exponentformat' property is an enumeration that may be specified as:
    - One of the following enumeration values:
