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.

       preferably in that order.
