NAME
kplot_get_datacfg — get data configurations for a plot
LIBRARY
library “libkplot”
SYNOPSIS
#include <cairo.h>
#include <kplot.h>
int
kplot_get_datacfg(
struct kplot *p,
size_t pos,
struct kdatacfg **cfgs,
size_t *cfgsz);
DESCRIPTION
The
kplot_get_datacfg function returns the
struct kdatacfg assigned to data attached with
kdata_attach_data(3),
kdata_attach_datas(3), and
kdata_attach_smooth(3). Since there may be more than one configuration per attachment,
kplot_get_datacfg will assign the array to
cfgs and the number of sources to
cfgsz. The
pos value refers to the order of attachment.
RETURN VALUES
kplot_get_datacfg returns 0 if there is no data source at that index, otherwise it returns non-zero and the cfgs and cfgsz are filled in.
