Contributed to the ex-em/EVUI repository by delivering nine new features and resolving eleven bugs over two months, focusing on interactive data visualization and charting improvements. Enhanced heat map usability with drag selection, click events, and precise index calculations, addressing floating-point errors and improving user interaction. Implemented dynamic axes scale detection and event emission, enabling responsive dashboards and accurate analytics. Refactored chart components for maintainability, updated documentation, and improved layout and labeling for dense charts. Utilized JavaScript, Vue.js, and charting libraries to ensure reliable rendering, robust option handling, and streamlined code, resulting in more actionable, maintainable, and user-friendly visualizations.

23 Commits • 8 Features
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.
