Latest Update: Version 1.4.0 - November 2025
Recent Improvements
Period Comparison Overlay - Layered (overlapped) display: wide gray bars for previous period in the background and narrow accent bars for current period on top; not side-by-side. Custom period labels and clear visual separation. Works with month/quarter/year granularities.
Granularity Controls (D/W/M/Q/Y) - One-click switches for date granularity with smart safeguards when source data is less detailed. Labels adapt per granularity.
Chart Type Toggle - Instant switch between line and bar per card with persistent preference and performance-safe transitions. Adaptive area fills and zero-line handling.
Advanced Number Formatting - Separate formats for KPI and statistics (auto/none/K/M/B) with configurable decimal places. Improved negative values coloring.
Visual Refinements - Optional zero line, custom light grid, thicker multi-color lines crossing zero, proportional scaling of the whole card.
Settings Scope - Per-workbook and per-worksheet settings storage, quick access to configuration, and safe defaults for any dataset with Date + Measure.
