SYNOPSIS

#include <kplot.h>

struct kdata *
kdata_array_alloc(struct kpair *pairs, size_t sz);

DESCRIPTION

The kdata_array_alloc function creates a reference-counted data sources for kplot(3). It is set to an array of data points pairs unless passed a NULL pointer, in which case x-values are set to the pair index from zero and y-values to zero. These values can be later reset with kdata_array_fill(3), or directly modified with kdata_array_add(3) or kdata_array_set(3).

RETURN VALUES

kdata_array_alloc returns NULL if memory allocation failed.
