NAME
notcurses_plot - high level widget for plotting
SYNOPSIS
#include <notcurses.h>
typedef enum {
NCPLOT_1x1, // full block █
NCPLOT_2x1, // full/lower blocks █▄
NCPLOT_1x1x4, // shaded full blocks █▓▒░
NCPLOT_4x1, // four vert levels █▆▄▂
NCPLOT_8x1, // eight vert levels █▇▆▅▄▃▂▁
} ncgridgeom_e;
typedef struct ncplot_options {
// channels for the maximum and minimum levels.
// lerp across the domain between these two.
uint64_t maxchannel;
uint64_t minchannel;
// number of "pixels" per row x column
ncgridgeom_e gridtype;
// independent variable is a contiguous range
int rangex;
// dependent min and max. set both equal to 0 to
// use domain autodiscovery.
uint64_t miny, maxy;
bool labelaxisd; // label dependent axis
bool exponentialy; // is dependent exponential?
bool vertical_indep; // vertical independent variable
} 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, uint64_t y);* int ncplot_set_sample(struct ncplot n, uint64_t x, uint64_t y);*
void ncplot_destroy(struct ncplot n);*
DESCRIPTION
NOTES
Neither exponentialy not vertical_indep is yet implemented.
RETURN VALUES
ncplot_create will return an error if miny equals maxy, but they are non-zero. It will also return an error if maxy < miny. An invalid gridtype will result in an error.
ncplot_plane returns the ncplane on which the plot is drawn. It cannot fail.
