Modification History


  Mark Hadfield, 1998-02:
    Written.
  Mark Hadfield, 2000-08:
    Updated for IDL2 syntax. Cleared out a lot of extraneous
    defaults from Init--were these originally put in to work
    around bugs in an IDL beta?
  Mark Hadfield, 2001-07:
    Minor changes.
  Mark Hadfield, 2003-05:
    Various changes made in upgrading to IDL 6.0, including
    setting default value of DEPTH_TEST_DISABLE to 1, so that
    the legend will be drawn over other graphic objects.
