KDATA_XMAX(3)		    Library Functions Manual		 KDATA_XMAX(3)

NAME
       kdata_xmax, kdata_ymax, -- find maxima in a data	source

LIBRARY
       library "libkplot"

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

       ssize_t
       kdata_xmax(const	struct kdata *data, struct kpair *kp);

       ssize_t
       kdata_ymax(const	struct kdata *data, struct kpair *kp);

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

RETURN VALUES
       If  the	data source has	zero entries, kdata_xmax and kdata_ymax	return
       -1.  Otherwise, they return the index of	the maximum.

SEE ALSO
       kdata_xmin(3), kdata_ymin(3), kplot(3)
