Apr 1, 20262026-04 Monthly Summary (ex-em/EVUI) Overview: Delivered a set of stability, usability, and correctness improvements across the charting stack, focusing on time-axis behavior, rendering robustness, and developer experience. Investments in tests and refactors reduce regression risk and accelerate future feature work while preserving backward-compatible behavior for end users. Key features delivered: - Time axis and label handling enhancements: retained data range while displaying intervals based on absolute time boundaries and added firstLabelFontStyle handling, improving consistency and readability of time-based charts. Representative commits include time axis range behavior with absolute boundary (b3bf6f0482a292a209d707b860db5cc89ee55232) and time scale refinements (8b3ea5fcf5d371f3e8a04719ca68315e6c8b08e2). - Time scale label and display policy improvements with tests: expanded test coverage for updated labeling policy to prevent regressions and ensure display rules align with feedback (test commits 3c8537fe9adf7a96a3bec304028d19b0b41169a0; 7b1ac8c8ae82622dc25ebd54d8d92c8424e8783e). - UI rendering robustness (out alignment, maxtip, and selection): fixed rendering thresholds and alignment for out-mode, ensured maxtip positions correctly, and enabled selection in areas with no data when selectedLabel is active (commits including 8bdf0221e26dfc669afbed1306e8e9ad92314354, 6d86939b16cb55e3d46236ff55bad8740bf6e4c1, 0414e3dc3ce86bb0d5fa3f3e528bc20ae30650de, 65f91befc8d5e6710e557bc80379a49602df2567, f62d03277b47acc565dc79c0408d5a4234d77d22). - Testing scaffolding and coverage improvements: introduced test-compatible example files and enhanced test suites to validate time-axis display policy and edge cases (3e2fd2c39d143bb87c960c4091b617d621592e24; 3c8537fe9adf7a96a3bec304028d19b0b41169a0; 0dfdda208ecb6a8b69813b080b84c5932326c3fd; 7b1ac8c8ae82622dc25ebd54d8d92c8424e8783e). - Code quality and maintenance: comprehensive refactor pass aligned with code-review feedback, whitespace cleanup, and removal of outdated flow explanations/options to simplify the API and reduce footprint (commits: 3b8ad1d435e87a18f356aeb27fe1f92eeb62814b; 342f807aa371e536d69c71c4700916aa2bbbe042; 704bfdc06bc81b9ab740836e00d6362a91608383; e44b3b4e2c3839cf32f331e5f99c61c6eeacda5f).
