Different interpolators change the curvature of the line. Options such as cardinal or Catmull-Rom interpolation can produce pleasing curves, but can also “hallucinate” maximum or minimum values that do not exist in the data. Use monotone interpolation for smooth curves that faithfully preserve monotonicity.
An area chart uses a filled shape to show changes in a quantitative value.
A stacked area chart depicts the sum of series of quantitative values using layered areas, while still enabling inspection of individual series.
By dividing an area chart into consecutive layers, horizon graphs present time-series data in a compact space while preserving resolution. Click the chart to change the number of layers. Though the chart size changes, the spatial resolution of the area chart stays constant.
