NAME
kdata_vector_append, kdata_vector_set — modify data of a vector data source
LIBRARY
library “libkplot”
SYNOPSIS
#include <cairo.h>
#include <kplot.h>
int
kdata_vector_append(
struct kdata *data,
double x,
double y);
int
kdata_vector_set(
struct kdata *data,
size_t pos,
double x,
double y);
DESCRIPTION
The
kdata_vector_append function sets the
x and
y values the pairs at
pos, or in the event of
kdata_vector_append, after growing vector data source allocated with
kdata_vector_alloc(3).
RETURN VALUES
kdata_vector_append returns 0 if the vector reallocation failed, the data source was not created with
kdata_vector_alloc(3), or if dependent data sources fail. Otherwise it returns non-zero.
