CALL LBFILL (IFTP, XCRA, YCRA, NCRA, INDX)
(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.
(an input expression of type INTEGER) is the number of points defining the rectangular box. Its value will always be five.
(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.
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)
CALL GSFACI (INDX)
CALL GFA (NCRA-1,XCRA,YCRA)
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.
To use LBFILL, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
