NAME

kdata_bucket_alloc — allocate bucket data for plotting

LIBRARY

library “libkplot”

SYNOPSIS

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

struct kdata *
kdata_bucket_alloc(size_t rmin, size_t rmax);

DESCRIPTION

The kdata_bucket_alloc function creates a reference-counted data sources for kplot(3), initially with x-values set to the pair index starting at rmin and y-values to zero. It is similar to kdata_array_alloc(3) except it uses a bucket data model: each integer within the range rmin (inclusive) to rmax (non-inclusive) corresponds to a specific bucket. Bucket values are modified with kdata_bucket_add(3) and kdata_bucket_set(3).

RETURN VALUES

kdata_bucket_alloc returns NULL if memory allocation failed.
