KDATA_XMIN(3)

NAME
kdata_xmin, kdata_ymin - find minima in a data source

LIBRARY
libkplot

SYNOPSIS
#include <cairo.h>
#include <kplot.h>
ssize_t
kdata_xmin(const struct kdata *data, struct kpair *kp);
ssize_t
kdata_ymin(const struct kdata *data, struct kpair *kp);

DESCRIPTION
The kdata_xmin and kdata_ymin functions find the minimum point in a data source, filling in kp if it is not NULL. The minimum point is the first minimum: thus, if multiple minima exist of the same value, the first will be returned.

RETURN VALUES
If the data source has zero entries, kdata_xmin and kdata_ymin return -1. Otherwise, they return the index of the minimum.
