linesseries
Linesseries is a term used in data visualization and time-series analysis to describe a sequence of linear representations that collectively approximate a data series. The concept emphasizes piecewise linear structure, where each segment is derived from a linear fit over a specified window or subinterval. The name combines "line" and "series" to reflect its dual nature as both a set of straight-line approximations and a temporally ordered series of fits.
In practice, a linesseries is produced by applying a linear regression to successive subsets of data, typically
As a representation, a linesseries highlights local trends and discontinuities while omitting some nonlinearity between segment
Applications include financial data visualization, signal processing, and exploratory data analysis, where a simple, interpretable summary
