NAME

       LBFILL - A routine that is called by LBLBAR (when the argument IFTP is non-zero) to fill
       portions of the bar. The default version of this routine does color fill by calling GSFACI
       and GFA.  A user-written version may be supplied to do a different kind of fill.

SYNOPSIS

       CALL LBFILL (IFTP, XCRA, YCRA, NCRA, INDX)

DESCRIPTION

       IFTP        (an input expression of type INTEGER) is the value of the argument IFTP from
                   the user's call to LBLBAR.

       XCRA, YCRA  (input arrays of type REAL) are real arrays containing the X and Y coordinates
                   of five points defining a rectangular box which is to be filled in some
                   manner. The fifth point defined by these arrays will always be a duplicate of
                   the first.

       NCRA        (an input expression of type INTEGER) is the number of points defining the
                   rectangular box. Its value will always be five.

       INDX        (an input expression of type INTEGER) is one of the indices from the array
                   LFIN, in the user's call to LBLBAR. Its value may be used as a color index or
                   as a pattern selector.

USAGE

       This routine is called by LBLBAR when LBLBAR's argument IFTP is non-zero.  LBFILL is
       called once for each sub-box in the label bar, using a statement of the form:

              CALL LBFILL (IFTP,XCRA,YCRA,NCRA,INDX)

       and is expected to fill the sub-box defined by its arguments. The default version of the
       routine looks like this:

              SUBROUTINE LBFILL (IFTP,XCRA,YCRA,NCRA,INDX)
                DIMENSION XCRA(*),YCRA(*)
                CALL GSFACI (INDX)
                CALL GFA (NCRA-1,XCRA,YCRA)
                RETURN
              END

       This version does color fill of the box, using the last argument as a color index. The
       user may replace this routine with a version that does any desired sort of fill; usually,
       this can be done by simply compiling the desired version, so that the default one from the
       package will not be loaded.

ACCESS

       To use LBFILL, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably
       in that order.
