Overview

Package lttb implements the Largest-Triangle-Three-Buckets algorithm for downsampling points

The downsampled data maintains the visual characteristics of the original line using considerably fewer data points.

Types

type Point

type Point[T constraints.Float] struct {
	X T
	Y T
}

Point is a point on a line

func LTTB

func LTTB[T constraints.Float](data []Point[T], threshold int) []Point[T]

LTTB down-samples the data to contain only threshold number of points that have the same visual shape as the original data
