NAME

       CPLBDR - Draws labels (an informational label, high and low labels, and line labels).

SYNOPSIS

       CALL CPLBDR (ZDAT, RWRK, IWRK)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_cplbdr (float *zdat, float *rwrk, int *iwrk)

DESCRIPTION

       All three arguments are arrays used in the last call to CPRECT, CPSPS1, or CPSPS2, the
       contents of which must not have been changed since that call.

       ZDAT        (REAL array, dimensioned as specified in the last call to CPRECT, CPSPS1, or
                   CPSPS2, input) is the data array.

       RWRK        (REAL array, dimensioned as specified in the last call to CPRECT, CPSPS1, or
                   CPSPS2, input/output) is the real workspace array.

       IWRK        (INTEGER array, dimensioned as specified in the last call to CPRECT, CPSPS1,
                   or CPSPS2, input/output) is the integer workspace array.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       CPLBDR may be called at any time after the initialization call to CPRECT, CPSPS1, or
       CPSPS2. If, during the last call to CPRECT, CPSPS1, or CPSPS2, the data being contoured
       were found to be essentially constant, then the constant-field label is drawn. Otherwise,
       the information label, the high and low labels, and/or the contour line labels are drawn,
       as follows:

       •      The information label is drawn only if the parameter 'ILT', which specifies the
              text of that label, is not blank.

       •      High labels are drawn only if the parameter 'HIT', which specifies the text of
              those labels, is not blank.

       •      Low labels are drawn only if the parameter 'LOT', which specifies the text of those
              labels, is not blank.

       •      Contour line labels are drawn only if the parameter 'LLP', which specifies how
              those labels are to be positioned, has an absolute value of 2 or 3, and if, for
              some I between 1 and 'NCL' inclusive, the Ith element of the parameter array 'CLU'
              has a value implying that contour lines at the contour level specified by the Ith
              element of 'CLV' are to be labeled.

       preferably in that order.
