NAME
notcurses_plot - high level widget for selecting from a set
SYNOPSIS
#include <notcurses.h>
typedef struct ncplot_options {
// channels for the maximum and minimum levels.
// lerp across the domain between these two.
uint64_t maxchannel;
uint64_t minchannel;
// independent variable is vertical, not horizontal
bool vertical_indep;
// number of "pixels" per row x column
ncgridgeom_e gridtype;
// independent variable is a contiguous range
uint64_t rangex;
// y axis min and max. set both equal to 0 for
// use with range autodiscovery.
int64_t miny, maxy;
bool exponentialy; // is y-axis exponential?
bool detectdomain;
} ncplot_options;
struct ncplot ncplot_create(struct ncplane n, const ncplot_options* opts);**
struct ncplane ncplot_plane(struct ncplot n);**
int ncplot_add_sample(struct ncplot n, uint64_t x, int64_t y);* int ncplot_set_sample(struct ncplot n, uint64_t x, int64_t y);*
void ncplot_destroy(struct ncplot n);*
DESCRIPTION
NOTES
RETURN VALUES
ncplot_create will return an error if detectdomain is set, and either miny or maxy are non-zero. It will also return an error if maxy < miny.
ncplot_plane returns the ncplane on which the plot is drawn. It cannot fail.
