NAME

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

SYNOPSIS

10       LBLBAR - Produces a complete label bar.
11
12       LBGETI - Retrieves current integer parameter values.
13
14       LBGETR - Retrieves current real parameter values.
15
16       LBSETI - Sets integer parameter values.
17
18       LBSETR - Sets real parameter values.

C-BINDING SYNOPSIS

21       c_lblbar
22       c_lbgeti

USER-MODIFIABLE INTERNAL ROUTINES

29       LBFILL - Fills label bars.
30

ACCESS

32       To use Labelbar routines, load the NCAR Graphics libraries ncarg,
33       ncarg_gks, and ncarg_c, preferably in that order.
34

MESSAGES

36       Various error conditions can occur in Labelbar.  Each of these results
37       in a call to the error-handling routine SETER, with a final argument
38       indicating that the error is recoverable; by default, an error message
39       is printed and execution is terminated, but, if you turn on error
40       recovery (as described in the "man" page for "error_handling"), you can
41       get control back.
42
43       The error messages are as follows; all should be more or less self-
44       explanatory.
45
46            LBGETI - UNCLEARED PRIOR ERROR
47            LBGETR - PARAMETER NAME NOT KNOWN - X
48            LBGETR - PARAMETER NAME TOO SHORT - X
49            LBGETR - UNCLEARED PRIOR ERROR
50            LBLBAR - ERROR EXIT FROM GQFACI
51            LBLBAR - ERROR EXIT FROM GQLWSC
52            LBLBAR - ERROR EXIT FROM GQPLCI
53            LBLBAR - ERROR EXIT FROM GQTXCI
54            LBLBAR - UNCLEARED PRIOR ERROR
55            LBSETI - UNCLEARED PRIOR ERROR
56            LBSETR - PARAMETER NAME NOT KNOWN - X
57            LBSETR - PARAMETER NAME TOO SHORT - X
58            LBSETR - UNCLEARED PRIOR ERROR
59
60       All of these should be more or less self-explanatory. Those that
61       complain of an error exit from a GKS routine probably imply that GKS
62       has somehow been put in the wrong state.  Others will result from using
63       an incorrect internal-parameter name in a call to one of the parameter-
64       access routines.  (The "X" will be replaced by the offending name.)
