Barlength

Barlength is a generic term used in computing, data visualization, and engineering to denote the length or size of a bar-shaped element. It is commonly used as a variable name or property holding a numeric value that defines how long the bar should appear or be manufactured.

In data visualization, barlength indicates the length of a bar in a bar chart. The value is mapped to a visual length by a scale, and the units can be pixels, millimeters, or chart units. The mapping may include normalization, baselining, and clipping to keep bars within the display area.

In user interfaces, barlength appears in progress bars and loading indicators, typically representing a percentage of completion. The internal length is often computed as a fraction of a container width and then converted to a pixel width for rendering.

In engineering and CAD contexts, barlength denotes the physical length of a bar-shaped component. It may be specified alongside other dimensions such as diameter or cross-section, and is subject to tolerances and manufacturing constraints.

In data exchange, barlength can be a field name in formats like JSON or CSV. Consistency in units and scaling is important when combining data from different sources.

Because barlength is a generic term, its precise meaning depends on the domain and accompanying metadata.
