Function: lttb()

function lttb(
   x, 
   y, 
   threshold): {
  x: Float64Array;
  y: Float64Array;
};

Defined in: data/downsample.ts:7

Largest-Triangle-Three-Buckets (LTTB) downsampling — reduce a series to threshold points while preserving its visual shape (peaks/troughs), the standard technique for plotting very long line series. First and last points are always kept.

Returns

{
  x: Float64Array;
  y: Float64Array;
}

x
