AXIS

        [GREG1\]AXIS  NAME  [A1  A2]  [/TICK Orien Small Big] [/LOCATION X Y
    Len] [/LABEL Value [ONLY]]  [/[NO]LOG]  [/ABSOLUTE]  [/UNIT  Valid_Unit]
    [/[NO]BRIEF]

    Makes  an  axis labelled from A1 to A2 at location X, Y, length Len. The
    current ORIENTATION determines the angle of the axis.

    The axis  scale  is  LINEAR  or  LOGARITHMIC  according  to  the  option
    /[NO]LOG.

    The  tick  orientation  "Orien" may be IN or OUT or NONE with respect to
    the BOX. Tick spacing can be defined by Small and Big.  The  orientation
    NONE  cancels  both ticks and labels. Labels for other "Orien" are drawn
    according to "Value", which may be N[one],  P[arallel]  or  O[rthogonal]
    (to  the  axis). If option /LABEL has the second argument ONLY, only the
    labels of the axis are written, not the axis nor the ticks. This feature
    allows use of different pens for the labels and the axis.

    AXIS  provides  default values for all these parameters according to the
    axis NAME (XLow, XUp, YLeft, YRight) and the current values used by BOX.

    AXIS creates a graphic segment named "AXIS".
