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.)
