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.
