Basic Downsampling Example
(Total count: 0)
This plugin for Highcharts
downsamples 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) used in this plugin is described in a
Master's thesis (see hdl.handle.net/1946/15343) in Computer Science by Sveinn Steinarsson
at the University of Iceland.
The topic of the thesis is how to downsample time series for visual representation
and was initially suggested by DataMarket.
JavaScript optimization was done with the help of Borgar Þorsteinsson.
