Blazor Linear Gauge Example - Tooltip Configuration

This sample depicts the Linear Gauge as a measuring scale and demonstrates tooltip interaction for precise value inspection. The gauge renders a continuous scale and uses tooltips to surface the value nearest the pointer or touch contact, enabling quick, contextual readout of the measured position.

Tooltips update dynamically as the pointer moves and snap to the closest tick or indicator so users receive immediate feedback. On touch‑enabled devices the same behavior is available via hover or tap, ensuring a consistent experience across pointer and touch input methods.

The sample highlights default tooltip placement, snapping behavior, and value formatting. Tooltips can be customized to show units, decimal precision, or additional contextual text, and the component exposes configuration and event hooks to alter content, placement, and update frequency to suit application needs.

Implementers should consider accessibility and responsiveness: provide clear numeric labels, preserve sufficient contrast and readable font sizes for tooltip content, and ensure the gauge remains navigable via keyboard and assistive technologies so value information is available to all users.

Use this pattern when you need an immediate numeric readout tied to a physical position on the gauge—such as previewing sensor output, adjusting controls, or calibrating targets—so users can validate values without leaving the visual context.
