ncl_labelbar (3) - Linux Manuals
ncl_labelbar: Creates a labeled, filled, rectangular bar to serve
Labelbar - Creates a labeled, filled, rectangular bar to serve as a key for a filled plot.
SYNOPSISLBLBAR - Produces a complete label bar.
LBGETI - Retrieves current integer parameter values.
LBGETR - Retrieves current real parameter values.
LBSETI - Sets integer parameter values.
USER-MODIFIABLE INTERNAL ROUTINESLBFILL - Fills label bars.
ACCESSTo use Labelbar routines, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
MESSAGESVarious 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.)
