+      SUBROUTINE AGUTOL (IAXS,FUNS,IDMA,VINP,VOTP)
+C
+C This routine is called to perform the mapping from the "user system"
+C along an axis to the "label system" along that axis or vice-versa.  It
+C may be replaced by the user in order to create a desired graph.  The
+C arguments are as follows:
+C
+C -- IAXS is the index of the axis being drawn.  Its value is 1, 2, 3,
+C    or 4, implying the left, right, bottom, or top axis, respectively.
+C
+C -- FUNS is the value of the parameter 'AXIS/s/FUNCTION.', which may be
+C    used to select the desired mapping function for axis IAXS.  It is
+C    recommended that the default value (zero) be used to specify the
+C    identity mapping.  A non-zero value may be integral (1., 2., etc.)
+C    and serve purely to select the code to be executed or it may be the
+C    value of a real parameter in the equations defining the mapping.
+C
+C -- IDMA specifies the direction of the mapping.  A value greater than
+C    zero indicates that VINP is a value in the user system and that
+C    VOTP is to be a value in the label system, a value less than zero
+C    the opposite.
+C
+C -- VINP is an input value in one coordinate system along the axis.
+C
+C -- VOTP is an output value in the other coordinate system along the
+C    axis.
+C
+C The default routine simply defines the identity mapping for all axes.
+C
+      VOTP=VINP
+C
+      RETURN
+C
+      END
