Labelbar(3NCARG)                          NCAR GRAPHICS                          Labelbar(3NCARG)

NAME
       Labelbar - Creates a labeled, filled, rectangular bar to serve as a key for a filled plot.

SYNOPSIS
       LBLBAR - Produces a complete label bar.

       LBGETI - Retrieves current integer parameter values.

       LBGETR - Retrieves current real parameter values.

       LBSETI - Sets integer parameter values.

       LBSETR - Sets real parameter values.

C-BINDING SYNOPSIS
       c_lblbar
       c_lbgeti
       c_lbgetr
       c_lbfill
       c_lbseti
       c_lbsetr

USER-MODIFIABLE INTERNAL ROUTINES
       LBFILL - Fills label bars.

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

MESSAGES
       Various error conditions can occur in Labelbar.  Each of these results in a call to the
       error-handling routine SETER, with a final argument indicating that the error is
       recoverable; by default, an error message is printed and execution is terminated, but, if
       you turn on error recovery (as described in the "man" page for "error_handling"), you can
       get control back.

       The error messages are as follows; all should be more or less self-explanatory.

            LBGETI - UNCLEARED PRIOR ERROR
            LBGETR - PARAMETER NAME NOT KNOWN - X
            LBGETR - PARAMETER NAME TOO SHORT - X
            LBGETR - UNCLEARED PRIOR ERROR
            LBLBAR - ERROR EXIT FROM GQFACI
            LBLBAR - ERROR EXIT FROM GQLWSC
            LBLBAR - ERROR EXIT FROM GQPLCI
            LBLBAR - ERROR EXIT FROM GQTXCI
            LBLBAR - UNCLEARED PRIOR ERROR
            LBSETI - UNCLEARED PRIOR ERROR
            LBSETR - PARAMETER NAME NOT KNOWN - X
            LBSETR - PARAMETER NAME TOO SHORT - X
            LBSETR - UNCLEARED PRIOR ERROR

       All of these should be more or less self-explanatory. Those that complain of an error exit
       from a GKS routine probably imply that GKS has somehow been put in the wrong state.
       Others will result from using an incorrect internal-parameter name in a call to one of the
       parameter-access routines.  (The "X" will be replaced by the offending name.)
