PLOT RGB

        PLOT  [3D_Var]  [/SCALING LIN|LOG|EQU [Rlcut Rhcut Glcut Ghcut Blcut

        PLOT [3D_Var] [/SCALING LUPTON [Beta]]

    THIS FEATURE IS CURRENTLY EXPERIMENTAL. Calling sequence, option  names,
    and behavior are subject to changes in the future.

    If  the  RG  buffer  (or the named variable, if any) is a 3D cube with 3
    planes, the command will plot it as a RGB image (R for 1st plane, G  for
    2nd plane, B for 3rd plane).

    The  extrema  are always (re)evaluated for each plane individually. That
    is, global cube extrema and RG%MIN and RG%MAX  (if  available)  are  ig-
    nored.

    The  default is to display the whole extrema ranges with linear scaling.
    This can be overridden with the option /SCALING, giving a custom scaling
    and cuts for each plane. Lupton scaling (combining each planes in a non-
    independent way) is available; Beta factor defaults to 3 but can be cus-
    tomized.
