docs: Complicated function that draws the high level mean plot on canvas4,
          draws all specimen, sample, or site interpretations according to the
          UPPER_LEVEL_SHOW variable, draws the fisher mean or fisher mean by
          polarity of all interpretations displayed, draws sample orientation
          check if on, and if interpretation editor is open it calls the
          interpretation editor to have it draw the same things.
