punktvälja

Punktvälja is a term used in some Scandinavian-language texts to describe an interaction pattern in data visualization and graphical interfaces, where a user selects data points within a plot, chart, or map. The concept encompasses various methods for choosing one or more points and using the resulting subset for further analysis or actions.

Etymology and scope: The word combines punkt (point) with välja (to choose/select in Swedish), and is often encountered in tutorials, design guides, and documentation aimed at Swedish-speaking or Nordic developers. It is not a universally standardized term in English-language references and may be used descriptively to refer to point selection as a common UI pattern rather than as a formal feature name.

Interaction patterns: Punktvälja includes several interaction styles, such as clicking individual points to toggle selection, clicking while holding a modifier key to multi-select, and outlining a region with a rectangular, polygonal, or freehand brush to select all points within the area. Visual feedback typically highlights selected points and may apply filters or enable subsequent operations (e.g., exporting data, applying analyses, or comparing subsets).

Applications and considerations: The pattern is widely used in analytics dashboards, scientific visualization, and geographic information systems. Design considerations include accessibility (keyboard and screen-reader support), touch and gesture compatibility, performance with large datasets, and clear feedback on selection state. De-selection and the ability to modify the selection efficiently are also important.
