Blazor Bullet Chart Range and Label Settings Example
This sample demonstrates a configurable Bullet Chart rendered with customization for axis labels and performance ranges. The example highlights how to tune visual presentation—label placement, range segments, and directional layout—so the component communicates progress and targets clearly.
The chart in this demo is presented in a right-to-left (RTL) layout: the feature bar, comparative bar, labels, and target indicators are mirrored to align with RTL reading flows and localized UI requirements. RTL rendering applies uniformly to axis orientation and element placement.
Axis labels and thresholds are controlled through the LabelPosition and Ranges properties. Use LabelPosition to adjust label alignment relative to the scale and the Ranges collection to define start/end values, color, and styling for discrete performance zones.
Tooltip support is enabled in this sample. Hover over a feature or comparative bar to reveal contextual values and range information, aiding interpretation without adding visual clutter.
Implementation notes: bind values and ranges to your view model so the chart updates with live data, verify label readability in RTL contexts, and choose color palettes with sufficient contrast. Ensure tooltips expose descriptive text via ARIA and that keyboard focus provides equivalent information. Adjust label rotation or trimming to avoid overlap and test with long labels. For dense datasets, limit displayed ranges and rely on tooltip details. Consider disabling animations or throttling updates for high-frequency data streams to preserve rendering performance.
