labelSettings

labelSettings is a configuration object used in data visualization and user interface components to control the rendering of text labels associated with visual elements such as data points, nodes, regions, or markers. It collects options that define how a label looks, where it is placed, and how its text is produced, enabling consistent styling within a component, chart, or map.

Typical properties include fontSize, fontFamily, fontWeight, color, and opacity, as well as textAlignment or alignment. Additional options cover padding, lineHeight, and maxWidth or maxLength. A formatter function or labelTemplate may determine the actual label text, while placement-related settings specify position, anchor, offsets, and rotation. Some implementations offer overlap handling rules, such as hiding labels when they collide or choosing smart placement.

Usage involves passing labelSettings as part of a component’s configuration. During rendering, the library consults these values when creating or updating label elements. If labelSettings is omitted, the component usually falls back to its default styling.

Considerations include performance for large datasets, since drawing many labels can slow rendering. Designers may enable truncation, wrapping, or overlap resolution to maintain readability. Accessibility and localization are also important: label text should support localization, and color contrast, font size, and readable type should comply with accessibility guidelines.

Label settings are commonly found in charts, diagrams, and mapping tools. They provide a centralized mechanism to standardize label appearance and behavior across related visual elements.
