NAME

       CPBACK - Draws a background for a contour plot.

SYNOPSIS

       CALL CPBACK (ZDAT, RWRK, IWRK)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_cpback (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

       You can call CPBACK at any time after the initialization call to CPRECT, CPSPS1, or CPSPS2.  What  CPBACK
       does depends on the value of the internal parameter 'MAP':

       •      If  'MAP'  is set to zero, CPBACK draws the perimeter of the current viewport by calling PERIM, in
              the utility Gridall, requesting 'ZDM'-1 major ticks on the horizontal sides of the  perimeter  and
              'ZDN'-1 major ticks on the vertical sides.  No minor ticks are drawn.

       •      If 'MAP' is set non-zero, CPBACK does nothing.

ACCESS

       To use CPBACK or c_cpback, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably  in
       that order.
