Documentation

An implementation of the largest triangle three buckets (lttb) algorithm for time series downsampling as described in Downsampling Time Series for Visual Representation. This is a Rust port of the original Javascript implementation.

Example

extern crate lttb;

use lttb::{DataPoint,lttb};

fn main() {
  let mut raw = vec!();
  raw.push(DataPoint::new(0.0, 10.0));
  raw.push(DataPoint::new(1.0, 12.0));
  raw.push(DataPoint::new(2.0, 8.0));
  raw.push(DataPoint::new(3.0, 10.0));
  raw.push(DataPoint::new(4.0, 12.0));

  // Downsample the raw data to use just three datapoints.
  let downsampled = lttb(raw, 3);
}
