This plugin is used for downsampleing the data before rendering the chart. The purpose is to try retain the visual characteristics of the original line using considerably fewer data points. The algorithm (called Largest-Triangle-Three-Buckets or LTTB) used in this plugin is described in a Master's thesis (see skemman.is/handle/1946/15343) in Computer Science by Sveinn Steinarsson

This Plugin is re-write of Original Repo
