Over the past year, contributed to the ex-em/EVUI repository by building and refining advanced charting features for real-time data visualization dashboards. Focused on enhancing chart tooltips, legend customization, and scatter chart rendering, the work addressed both user experience and performance, including optimizations like offscreen blitting and O(1) deduplication for dense data. Leveraged JavaScript, Vue.js, and canvas rendering to deliver reliable, interactive charts, while maintaining robust documentation and regression tests. Tackled complex issues such as color fidelity, event handling, and cross-chart consistency, resulting in improved maintainability, visual accuracy, and efficient data handling for high-frequency, data-intensive applications.

Jun 1, 2026June 2026 focused on performance, correctness, and cross-chart consistency for EVUI charts. Delivered cross-chart axes data max-change emission to support efficient auto-scaling without rescanning, enhanced real-time scatter rendering via offscreen blit with deduplication, and a targeted edge clipping fix. Reorganized fast-path code for maintainability, and updated documentation and tests to reflect new behavior and performance characteristics. The work reduces per-tick CPU usage, improves visual correctness, and strengthens the charting foundation for data-intensive dashboards.

Feb 1, 2026February 2026: EVUI delivered a new External Legend feature and updated dependency versions to strengthen security and compatibility. External Legend enables rendering and customizing legends outside the chart area, with documentation updates and enhancements to chart series configuration (including fill and fillColor). The change also improves legend data refresh when toggling legend options and bumps the package version to 3.4.213. Dependency updates in package-lock.json improve security posture and compatibility with downstream packages. Overall impact: richer chart customization, clearer UX, and reduced maintenance risk.

Dec 1, 2024December 2024 (ex-em/EVUI): Fixed a critical visualization issue in RealTimeScatter where per-point fill color was not applied correctly. Updated the color selection logic to prioritize item-specific colors and gracefully fallback to the default fill color, ensuring per-point customization is visually accurate in real-time scatter plots. The change is tracked in commit 53a4c355ecfd459600326b0b4e6565531cb359de and addresses issue #1822/#1823. Impact: restored accuracy and consistency of color-coding, enhancing data readability and trust in visual analytics. Skills demonstrated: debugging frontend color-model logic, collaborating with issue trackers, JavaScript/TypeScript, and UI data visualization.
