Hyun built and enhanced interactive charting features for the ex-em/EVUI repository, focusing on heat map visualizations and dashboard reliability. Using JavaScript and Vue.js, Hyun delivered interactive selection and legend-click events, improved axis labeling, and addressed floating-point precision in index calculations to ensure accurate data exploration. The work included refactoring data structures for maintainability, updating dependencies, and implementing robust scrollbar logic to synchronize DOM updates and chart rendering. Hyun also improved documentation and technical clarity through targeted code cleanups and tests. These contributions deepened the codebase’s reliability, usability, and maintainability, supporting more actionable and responsive data visualization workflows.

Mar 1, 2026March 2026 delivered significant enhancements to EVUI’s chart interactivity, reliability, and maintainability, enabling more responsive dashboards and robust data visualization. Key features shipped include dynamic axes scale change detection with emission and the scaleChange option, plus corrected event payloads to reliably convey min/max steps. Heatmap interactivity was expanded with a click-legend emission, unlocking richer analytics workflows. Labeling and layout improvements were implemented via ShowLastLabel with proper alignment when grid lines are used, improving readability in dense charts. A comprehensive set of scrollbar fixes and refactors ensured option changes reflect in the chart, DOM synchronization is stable, and rendering bugs (notably in bar chart scrollbar) are resolved, alongside improved update logic. Decimal point calculation logic was fixed and covered with tests, and several targeted refactors cleaned up helpers, simplified setDecimal, and removed unused label rendering. These efforts reduce maintenance costs, increase reliability, and empower faster decision-making through more accurate, actionable visuals.
