This is something the BOM asked me to do so thanks for the
reminder.  You can override the default Units by a new
method of ScalarMap:

  public void setOverrideUnit(Unit unit) throws VisADException;

The unit must be convertible with the default Unit of the
ScalarMap's RealType, and this method should be called before
any data are displayed.

This will affect the ScalarMap's setRange(), getRange()
getScale() and makeScale() methods.
