Hi Henrique,

In version 3.02, I added two new functions
  - TAxis::SetNoExponent (also in the TAxis context menu)
    with which you can enable/disable the 10^N notation

  -TGAxis::SetMaxDigits. This is a static function that you can call
   to specify the maximum number of digits in labels before switching
   to the 10^N notation (global setting).
