groeilijn

Groeilijn is a Dutch term that literally means "growth line." In Dutch-language usage, the words describe a line or curve that represents growth or progression over time. The exact meaning tends to depend on the domain in which it is used.

In biology and botany, groeilijn can refer to lines that indicate increments of growth on organisms or their structures. For example, growth rings in wood or shells are sometimes described as groeilijnen because they mark periods of active growth. In plant physiology or horticulture, the term may be used to discuss growth trajectories when assessing the development of a plant or crop.

In data presentation and economics, groeilijn is often used to describe a trend line or growth curve on charts and dashboards, illustrating how a variable increases over time. Depending on the context, the line may be derived from observed data or used as a forecast, with related metrics such as growth rate or compound annual growth.

There is no single canonical definition of groeilijn; practitioners may prefer more specific terms such as groeicurve, groeitraject, or trendlijn, depending on the discipline. The term is more common in informal or general-language contexts than in formal technical writing, and its interpretation should be inferred from surrounding text.
