時系列データの始点を設定する。
Set the starting point for time-series data.
Commonly used in mathematics, graphs, routes, and data analysis.
'始点' is typically used for abstract or technical starting points (e.g., graphs, data), while '出発点' refers to physical departure points (e.g., train stations, journeys).
Composed of '始' (to begin) and '点' (point). The term emerged in modern Japanese as a compound to describe the origin of a process or measurement.
Unlike '出発点' (departure point), '始点' is more commonly used in technical or mathematical contexts to denote the origin of a coordinate system or data sequence.
