Name: GRAFMP  24
The routine GRAFMP plots a geographical axis system.
The call is:  CALL GRAFMP (XA, XE, XOR, XSTP, YA, YE, YOR, YSTP)
         or:  void grafmp (
                     float xa, float xe, float xor, float xstp, 
                     float ya, float ye, float yor, float ystp);
XA, XE        are the lower and upper limits of the X-axis.
XOR, XSTP     are the  first X-axis label  and the step  between
              labels.
YA, YE        are the lower and upper limits of the Y-axis.
YOR, YSTP     are the  first Y-axis label  and the step  between
              labels.
Notes:      - GRAFMP  must be  called  from level 1 and sets the
              level to 2.
            - The axes  must  be linear and scaled in  ascending
              order.  In general, X-axes must be scaled  between
              -180 and 180 degrees and Y-axes between -90 and 90
              degrees.
            - For  elliptical  projections,  the plotting  of an
              axis system will be suppressed.  This will also be
              done for azimuthal projections with YE - YA > 90.
            - The statement  CALL GRIDMP (I, J) overlays an axis
              system with a grid of longitude and latitude where
              I and J  are the number  of grid lines between la-
              bels in the X- and Y-direction.

         or:  void xaxmap (float a, float b, float or,

              wise direction.  If NT = 1,  they are plotted in a
              counter-clockwise direction.
NY            defines the horizontal  position  of the X-axis. A
              secondary  axis  must be located  inside  the axis
              system.

              counter-clockwise direction.

                                        Default: CTYPE = 'CYLI'.
Notes:      - For cylindrical equidistant projections,  the sca-
              ling parameters in GRAFMP must be in the range:
                         -540 <= XA <= XE <= 540
                         -180 <= YA <= YE <= 180
              For Mercator procektions:
                         -540 <= XA <= XE <= 540
                         - 85 <= YA <= YE <=  85
              For cylindrical equal-area projections:
                         -540 <= XA <= XE <= 540
                         - 90 <= YA <= YE <=  90
              For elliptical projections:
                         -180 <= XA <= XE <= 180
                         - 90 <= YA <= YE <=  90
              For conical projections:
                         -180 <= XA <= XE <= 180
                            0 <= YA <= YE <=  90  or
                         - 90 <= YA <= YE <=   0
              For azimuthal projections with  YE - YA > 90,  the
              hemisphere around the map pole is projected onto a
              circle. Therefore,  the hemisphere can be selected
              with the map pole. The plotting of the axis system
              will be  suppressed.
              If YE - YA <= 90, the part of the globe defined by
              the  axis scaling  is projected  onto a rectangle.
              The map pole will be set by GRAFMP to  ((XA+XE)/2,
              (YE+YA)/2).  The scaling parameters must be in the
              range:
                         -180 <= XA <= XE <= 180 and
                                 XE -  XA <= 180
                         - 90 <= YA <= YE <=  90
          -   For all projections except the default projection,
              longitude and latitude coordinates will be projec-
              ted  with the same scaling factor  for the X-  and
              Y-axis.  The scaling factor is  determined  by the
              scaling of the  Y-axis  while the  scaling  of the
              X-axis  is used  to centre the map.  The longitude
              (XA+XE)/2  always lies  in the centre  of the axis
              system.
