Chart Guru Changelog

All notable changes to this package will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[1.3.0] - 2026-10-05

Section titled “[1.3.0] - 2026-10-05”
  • Kept Chart Graphic data-source refreshes from interrupting active pointer edits in the inspector.
  • Generated bounded OHLC and calendar dates for mock candlestick charts, preserving scalar chart values, deterministic output and per-series streaming continuity.
  • Redesigned the Mock Chart Data Source Generation section with a live Idle, Streaming or Inactive state badge and full-width actions; Start Streaming and Stop Streaming now enable only when applicable, and all generation actions apply to every selected source.
  • Redesigned the Chart Designer settings pane for narrow and wide layouts with shrinking tabs, a proportional label column, series cards with theme or custom colors, a value grid that becomes stacked records when its columns no longer fit, editable candlestick data, the heat-map color scale, chart-type-aware sections, retained conditional controls and tooltips for every setting.
  • Added retained data tooltips with customizable content and styling, shape-aware hit testing, hover and tap-to-pin interaction, editor controls and a runnable example for Canvas and UI Toolkit charts.
  • Added linked chart selection, stable selection after data reordering, optional X, Y and XY drag brushes, and consistent clearing of point and range selections.
  • Added chart accessibility descriptions and accessible navigation, Unity 6 native accessibility support, audio graphs, semantic CSV and JSON export, and composed PNG export from Canvas charts.
  • Added typed tabular data with filtering, sorting, calculations, aggregation, windows and facets, plus explicit mark encodings, stable live bindings and function, vector and regression plots.
  • Expanded the public API reference for typed data frames, fluent plots, tooltips and lifecycle utilities.
  • Added observable asynchronous data refresh with safe cancellation, latest-request handling, response metadata and polling backoff. Runtime and environment-provided credential headers are kept out of saved chart assets.
  • Improved Swift chart import and generated C# for numeric ticks, symbols, rectangle ranges, annotations, formatting, typography and overflow settings, with clearer diagnostics for unsupported options.
  • Improved bar sizing and corners, grouped-bar alignment, axis spacing and visibility, annotation placement, symbol shapes, gradients and opacity to better match the authored chart.
  • Preserved annotations, accessibility, effects, scale domains and styling when changing chart types or projecting their data into other renderers, and corrected stored pose values used by 3D extensions.
  • Improved Canvas chart resizing, pixel-density changes and label replacement, preventing recursive layout updates, duplicated labels and stale saved text.
  • Improved UI Toolkit chart attachment, cleanup, animation timing and boundary hit testing, including tooltip initialization before the first panel attachment.
  • Reduced allocations and redundant rendering work in stable updates, live bindings, animation, legends and text, and improved cached chart compilation and domain queries.
  • Improved gallery responsiveness, incremental preview rendering, resource cleanup and preservation of browser settings across reloads.
  • Restored UI Toolkit compilation on Unity 2022.3 and 2023.x and improved editor cleanup, rendering and cache reset on newer Unity versions.
  • Simplified optional LED Studio integration imports so supported installed companions activate without project-wide scripting defines.
  • Improved sample Input System wiring and first-run guidance, keeping bundled installations quiet while retaining access from the Tools menu.
  • Included the Input System required by Chart Designer scene creation and bundled interactive examples, fixing clean installation compilation on Unity 2022.3.
  • Added AI guidance for setup, code and editor authoring, live data, styling and morphing.

[1.2.0] - 2026-07-28

Section titled “[1.2.0] - 2026-07-28”
  • Rebuilt the Chart Designer, galleries, welcome experience, and all chart authoring inspectors with polished responsive UI Toolkit layouts.
  • Added consistent sections, validation, live previews, compact asset creation, and safer editable data lists across chart assets, data sources, themes, components, and graphics.
  • Tightened Chart Designer data editing with aligned table columns, compact labels, clearer gradient controls, compact panel toggles, and unclipped code actions across narrow and wide layouts.
  • Reorganized inspector settings around focused concepts with clearer tooltips, progressive disclosure, aligned controls, and accessible inline data settings.
  • Moved mock data generation actions to the top of the workflow and added compact theme creation beside theme fields.
  • Reduced scripting clutter by keeping chart layout, rendering, authoring translation, text management, and preview implementation internal.
  • Chart mark opacity now applies consistently to bars, points, sectors, and other mark types.

[1.1.0] - 2026-06-29

Section titled “[1.1.0] - 2026-06-29”
  • Added optional LED Studio integration so Chart Guru charts can drive LED Studio boards through a nested integration package
  • Added multiple UITK sample scenes
  • Added chart texture output for integrations, including an option to capture titles, axis labels, legends, and data labels together with the chart image
  • Improved data label placement for horizontal bars, pie charts, donut charts, and UI Toolkit charts
  • Added pie and donut leader-line labels for clearer small-slice labeling
  • Improved UI Toolkit chart rendering with better axis label rotation, chart title anchoring, copied chart styling, and data label alignment
  • Fixed origin axis and grid line layering so zero baselines stay aligned during chart updates and morphs
  • Improved legend sizing and truncation for side legends and compact layouts
  • Improved render pipeline compatibility for Chart Guru shaders in URP and built-in render pipeline projects
  • Improved edit-mode animation, streaming, and preview timing through shared timing controls
  • Improved TextMeshPro word-wrapping compatibility across Unity versions
  • Updated documentation for LED Studio integration, texture output, shader compatibility, and release validation rules
