NAME
     kdata_vector_append,  kdata_vector_set  --  modify  data  of  a vector data
     source

LIBRARY
     libkplot

SYNOPSIS
     #include <cairo.h>
     #include <kplot.h>

     int
     kdata_vector_append(struct kdata *data, double x, double y);

     int
     kdata_vector_set(struct kdata *data, size_t pos, double x, double y);

DESCRIPTION
     The kdata_vector_append function sets the x and y values the pairs at  pos,
     or  in  the  event of kdata_vector_append, after growing vector data source
     allocated with kdata_vector_alloc(3).

RETURN VALUES
     kdata_vector_append returns 0 if the vector reallocation failed,  the  data
     source  was  not  created	with kdata_vector_alloc(3), or if dependent data
     sources fail.  Otherwise it returns non-zero.
