KDATA_BUCKET_ALLOC(3) Library Functions Manual KDATA_BUCKET_ALLOC(3) NAME kdata_bucket_alloc -- allocate bucket data for plotting 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.
